How to solve the error in the below email content in C#

I am using C# MVC Architecture.
I am going to retrieve the questions from the database and display in the email content as a list of questions.
Below is the method of the email template.
public bool SendJobAcceptanceToRecruiter(string recruiterName, string recruiterEmail, string jobTitle,string joblink, string mailBody, string organization, List<JobQuestion> ques)
{
string subject = "Job Advert Accepted - " + jobTitle + "-" + organization;
var generaltemplate = GetEmailTemplate("GENERAL EMAIL TEMPLATE");
var template = "<br/>Hello " + organization + "<br/>" +
"<br/>Your Job Advert has now been accepted.<br/>" +
"<br/>View Job Posted: " + joblink + "<br/>" +
"<br/>Questions Posted: " + ques + "<br/>" +
"<br/>Please contact us if you need more information.<br/>";
var body = generaltemplate.Replace("#Content", template);
body = body.Replace("#Orgname", organization);
body = body.Replace("#JobLink", joblink) + GetEmailFooter();
var result = _emailProvider.SendEmail(recruiterEmail, subject, body, true);
return result;
}
Here for the List of questions, I get the questions as below.
I want to display the 'Question' in the second image as list of questions(In the above case as the count is 7,want to display the 7 questions) with numbering starting from 1.(Number of questions may differ according to the advert.) as a list in the email content.
Every other details(jobTitle,JobLink,RecruiterEmail etc..) are displayed in the email.
Only the 'ques' under Questions Posted: in the email content are displayed as
[![enter image description here][3]][3]
I want the content to be displayed as,
1.Question 1
2.Question 3
3.Question 3
...
How can I solve this?

You need to "unfold" the list of questions, if you do that, you'll have all the freedom you need.
In stead of:
"<br/>Questions Posted: " + ques + "<br/>"
use something like this:
"<br/>Questions Posted: " + string.Join(", ",Enumerable.Range(0, ques.Count()).Select(n => n.Description).ToArray()) + "<br/>"
Or for better readability:
var template = "<br/>Hello " + organization + "<br/>" +
"<br/>Your Job Advert has now been accepted.<br/>" +
"<br/>View Job Posted: " + joblink + "<br/>" +
"<br/>Questions Posted: ";
foreach(var question in ques)
template += $"somthing {question.Description} something"
template += "<br/>Please contact us if you need more information.<br/>";
var body = generaltemplate.Replace("#Content", template);
Further optimization: use a StringBuilder:
var sb = new StringBuilder();
sb.AppendLine("<br/>Hello " + organization + "<br/>");
sb.AppendLine("<br/>Your Job Advert has now been accepted.<br/>");
sb.AppendLine("<br/>View Job Posted: " + joblink + "<br/>");
sb.AppendLine("<br/>Questions Posted: ");
foreach(var question in ques)
{
sb.AppendLine($"somthing {question.Description} something");
}
sb.AppendLine("<br/>Please contact us if you need more information.<br/>");
var body = generaltemplate.Replace("#Content", sb.ToString());
Addition: for numbering you have various options. Here's a simple one to understand:
var sb = new StringBuilder();
sb.AppendLine("<br/>Hello " + organization + "<br/>");
sb.AppendLine("<br/>Your Job Advert has now been accepted.<br/>");
sb.AppendLine("<br/>View Job Posted: " + joblink + "<br/>");
sb.AppendLine("<br/>Questions Posted: ");
int number = 0;
foreach(var question in ques)
{
sb.AppendLine($"QUESTION {++number}");
sb.AppendLine($"somthing {question.Description} something");
}
sb.AppendLine("<br/>Please contact us if you need more information.<br/>");
var body = generaltemplate.Replace("#Content", sb.ToString());

how to efficiently simplify repetitive code {Objects/Strings}

First, I apologize for the length of this, but it's all I knew when I started. Now I'm experimenting with the foreach, List<t> and TreeView classes to avoid repetition as recmomended by SO community.
The form will collect information via text boxes, allow attachments of files with file dialogs and collate all info into a neat HTML bodied email. We sell slabs.. and my original code looked a little like this:
private void PrepareReturnEmailTwoSlabs()
{
LoadSettings();
string Fname = Properties.Settings.Default.FabricatorName;
string Facc = Properties.Settings.Default.FabricatorAccountNo;
string Fadd1 = Properties.Settings.Default.FabricatorAddress1;
string Fadd2 = Properties.Settings.Default.FabricatorAddress2;
string Ftown = Properties.Settings.Default.FabricatorTown;
string Fcounty = Properties.Settings.Default.FabricatorCounty;
string Fpostcode = Properties.Settings.Default.FabricatorPostcode;
string Fphoneno = Properties.Settings.Default.FabricatorPhone;
string Femail = Properties.Settings.Default.FabricatorEmail;
string Fclient = Properties.Settings.Default.ClientManagerEmail;
string Fcentre = Properties.Settings.Default.CentreEmail;
string FQt = Properties.Settings.Default.QTEmail;
string Dateofinv = dateTimePicker1.Value.ToShortDateString();
string Inv = textBox13.Text;
string Material1 = textBox14.Text;
string Thick1 = comboBox8.SelectedValue.ToString();
string Batch1 = textBox44.Text;
string Reason1 = comboBox1.SelectedValue.ToString();
string Notes = textBox18.Text;
string Thick2 = comboBox7.SelectedValue.ToString();
string Material2 = textBox15.Text;
string Batch2 = textBox45.Text;
string Reason2 = comboBox2.SelectedValue.ToString();
if (Thick2 == null)
{
Thick2 = "not selected";
}
if (Material2 == null)
{
Material2 = "not selected ";
}
if (Batch2 == null)
{
Batch2 = "not selected ";
}
if (Reason2 == null)
{
Reason2 = "not selected ";
}
GenerateUniqueRefReturn();
//construct email
var message = new MimeMessage();
message.From.Add(new MailboxAddress("************", "***************"));
message.To.Add(new MailboxAddress("**********", "********"));
message.Subject = "Return" + " " + Returnid;
//different message bodies dependant on how many slabs are chosen
TextPart body2 = new TextPart("html")
{
Text = #"Please See Below Information" + "<br/>" +
"<h4>Return ID: " + " " + Returnid + "</h4>" + "<br/>" +

"<b>Notes:" + " " + Notes
};
var builder = new BodyBuilder();
//check for return attachment and if found, assign attachment to message via bodybuilder
if (checkBox5.Checked)
{
builder.TextBody = body2.Text;
builder.HtmlBody = body2.Text;
builder.Attachments.Add(ReturnAttachment1);
message.Body = builder.ToMessageBody();
}
if (checkBox7.Checked)
{
builder.TextBody = body2.Text;
builder.HtmlBody = body2.Text;
builder.Attachments.Add(ReturnAttachment1);
builder.Attachments.Add(ReturnAttachment2);
message.Body = builder.ToMessageBody();
}
if (checkBox6.Checked)
{
builder.TextBody = body2.Text;
builder.HtmlBody = body2.Text;
builder.Attachments.Add(ReturnAttachment1);
builder.Attachments.Add(ReturnAttachment2);
builder.Attachments.Add(ReturnAttachment3);
message.Body = builder.ToMessageBody();
}
else
{
message.Body = body2;
}
//Connection to SMTP and Criteria to Send
using (var client = new SmtpClient())
{
// For demo-purposes, accept all SSL certificates (in case the server supports STARTTLS)
client.ServerCertificateValidationCallback = (s, c, h, e) => true;
client.Connect("smtp.gmail.com", 587, false);
// Note: only needed if the SMTP server requires authentication
client.Authenticate("***************#********.com", "*********");
client.Send(message);
client.Disconnect(true);
This code was repeated all the way up to five slabs. So now, I have a class:
{
public string Thickness { get; set; }
public string Material { get; set; }
public string Batch { get; set; }
public Slab(string Thick, string Mat, string Batchno)
{
Thickness = Thick;
Material = Mat;
Batch = Batchno;
}
}
A List that holds this object:
private void button1_Click(object sender, EventArgs e)
{
string t = comboBox1.SelectedValue.ToString();
string m = comboBox2.SelectedValue.ToString();
string b = textBox6.Text;
Slab S = new Slab(t, m, b);
allSlabs.Add(S);
PaintTree();
}
public void PaintTree()
{
int ParentIndex;
TreeSlabs.Nodes.Clear();
foreach (Slab slab in allSlabs)
{
TreeSlabs.BeginUpdate();
TreeSlabs.Nodes.Add("Slab" + " " + (allSlabs.IndexOf(slab) + 1).ToString());
ParentIndex = allSlabs.IndexOf(slab);
TreeSlabs.Nodes[ParentIndex].Nodes.Add("Thickness: " + $"{slab.Thickness}");
TreeSlabs.Nodes[ParentIndex].Nodes.Add("Material: " + $"{slab.Material}");
TreeSlabs.Nodes[ParentIndex].Nodes.Add("Batch: " + $"{slab.Batch}");
TreeSlabs.EndUpdate();
}
}
Now i want to create a foreach.. that iterates through each node.. and collects the info from the parent and its children foreach node, and somehow instantiate new HTML methods for each node..
Foreach Node:
Compose HTML Line - new HTML
Slab 1:
Thickness:
Material
Batch
Slab 2:... etc
If theres 8 nodes, it generates 8 of those bodies. i can think of ways.. but i KNOW they're defintely not the correct ways to go about it based on what ive read and seen out there.
Many Thanks

You don't need to iterate through the tree and try to reclaim the data you put into it from the List of Slabs; it would be simpler to enumerate the List:
By the way, some other tips:
don't beginupdate/endupdate inside the loop, do it outside
the Add method that adds a node to a tree returns the node it added; you don't have to find it again by index, just capture it var justAdded = rootnode.Add("parent node"); and then add your thickness etc to it justAdded.Nodes.Add("thickness..."). The only add command that doesn't return the added mode is the one that takes a treenode type object; it doesn't need to return it because you already have it
consider adding a method to your slab to return some html, to simplify things
you can tidy all that html up with some string interpolation like you did with your $"{slab.thickness}" etc

C# - How to detect browser type

I'm running Selenium with C# for my automation testing on multiple browsers (IE, FF, Chrome) and there is one part of my test that passes for Chrome but not Firefox.
Is there a way to detect the browser type that is currently being used during the automated test?

You can install UAParser from Nugget :
https://www.nuget.org/packages/UAParser/
It will read the client header and Parse it.
Exemple:
//string uaString = "Mozilla/5.0 (iPhone; CPU iPhone OS 5_1_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9B206 Safari/7534.48.3";
// Request the header
string uaString= HttpContext.Current.Request.UserAgent.ToString();
// get a parser with the embedded regex patterns
var uaParser = Parser.GetDefault();
// get a parser using externally supplied yaml definitions
// var uaParser = Parser.FromYamlFile(pathToYamlFile);
// var uaParser = Parser.FromYaml(yamlString);
ClientInfo c = uaParser.Parse(uaString);
Console.WriteLine(c.UserAgent.Family); // => "Mobile Safari"
Console.WriteLine(c.UserAgent.Major); // => "5"
Console.WriteLine(c.UserAgent.Minor); // => "1"
Console.WriteLine(c.OS.Family); // => "iOS"
Console.WriteLine(c.OS.Major); // => "5"
Console.WriteLine(c.OS.Minor); // => "1"
Console.WriteLine(c.Device.Family); // => "iPhone"

Use the following code
System.Web.HttpBrowserCapabilities browser = Request.Browser;
string s = "Browser Capabilities\n"
+ "Type = " + browser.Type + "\n"
+ "Name = " + browser.Browser + "\n"
+ "Version = " + browser.Version + "\n"
+ "Major Version = " + browser.MajorVersion + "\n"
+ "Minor Version = " + browser.MinorVersion + "\n"
+ "Platform = " + browser.Platform + "\n"
+ "Is Beta = " + browser.Beta + "\n"
+ "Is Crawler = " + browser.Crawler + "\n"
+ "Is AOL = " + browser.AOL + "\n"
+ "Is Win16 = " + browser.Win16 + "\n"
+ "Is Win32 = " + browser.Win32 + "\n"
+ "Supports Frames = " + browser.Frames + "\n"
+ "Supports Tables = " + browser.Tables + "\n"
+ "Supports Cookies = " + browser.Cookies + "\n"
+ "Supports VBScript = " + browser.VBScript + "\n"
+ "Supports JavaScript = " +
browser.EcmaScriptVersion.ToString() + "\n"
+ "Supports Java Applets = " + browser.JavaApplets + "\n"
+ "Supports ActiveX Controls = " + browser.ActiveXControls
+ "\n"
+ "Supports JavaScript Version = " +
browser["JavaScriptVersion"] + "\n";

How to send picture to email body in WinForms?

I have a C# Winforms application I'm working on in Visual Studio 2010, the page in question is a bug reporting form - I have all the details set, email sends fine etc. My issue is attaching a screenshot to the email in the body, I have code set up to allow users to find and select a screenshot they take and attach to the form, but in the body itself it just gives me the text "System.Windows.Forms.Picturebox", or various similarities to that if I try .image.
I've had a look around via Google and here, but can only find topics that are to do with embedding the image or attaching it (and thus require to enter in a specific folder/image etc), whereas my users will be attaching their own image and name from different places. Is there anyway to get the image to be picked up without having to hardcode a location and name that my users will have to follow each time?
Code below:
private void btnBugEmail_Click(object sender, EventArgs e)
{
Cursor.Current = Cursors.WaitCursor;
try
{
SmtpClient client = new SmtpClient("details here");
MailMessage message = new MailMessage();
message.From = new MailAddress("email here");
string mailBox = txtBugAdd.Text.Trim();
message.To.Add(mailBox);
string mailFrom = txtEmailFromBug.Text.Trim();
message.CC.Add(mailFrom);
string mailCC = txtMailCCBug.Text.Trim();
message.Bcc.Add(mailCC);
message.IsBodyHtml = true;
message.Body = "Bug Report - please see below: " +
"\n" + "<br>" + "<b>" + "1. What were you doing at the time of the error?" + "</b>" +
"\n" + "<br>" + rtbTimeOfError.Text +
"\n" + "<br>" + "<b>" + "2. Are you able to repeat the steps and achieve the same error?" + "</b>" +
"\n" + "<br>" + rtbCanRepeat.Text +
"\n" + "<br>" + "<b>" + "3. Does this problem happen again if you change any of the details you have entered?" + "</b>" +
"\n" + "<br>" + rtbChangeDetails.Text;
message.Subject = "Bug Report";
var image = pboxBugImage.Image;
using(var ms = new MemoryStream())
{
image.Save(ms, ImageFormat.Jpeg);
message.Attachments.Add(new Attachment(ms, "Screenshot.jpg"));
client.Credentials = new System.Net.NetworkCredential("credentials here");
client.Port = System.Convert.ToInt32(25);
client.Send(message);
}
new Endpage().Show();
this.Close();
}
catch
{
MessageBox.Show("my comment here");
}
}

Take a look to the following link
system.net.mail.mailmessage.attachments
You cannot put a winforms control inside the mailmessage :) it is outputted with ToString()... that is what you see in mail
Example
private void btnBugEmail_Click(object sender, EventArgs e)
{
Cursor.Current = Cursors.WaitCursor;
try
{
SmtpClient client = new SmtpClient("details here");
MailMessage message = new MailMessage();
message.From = new MailAddress("email here");
string mailBox = txtBugAdd.Text.Trim();
message.To.Add(mailBox);
string mailFrom = txtEmailFromBug.Text.Trim();
message.CC.Add(mailFrom);
string mailCC = txtMailCCBug.Text.Trim();
message.Bcc.Add(mailCC);
message.IsBodyHtml = true;
message.Body = "Bug Report - please see below: " +
"\n" + "<br>" + "<b>" + "1. What were you doing at the time of the error?" + "</b>" +
"\n" + "<br>" + rtbTimeOfError.Text +
"\n" + "<br>" + "<b>" + "2. Are you able to repeat the steps and achieve the same error?" + "</b>" +
"\n" + "<br>" + rtbCanRepeat.Text +
"\n" + "<br>" + "<b>" + "3. Does this problem happen again if you change any of the details you have entered?" + "</b>" +
"\n" + "<br>" + rtbChangeDetails.Text;
message.Subject = "Bug Report";
var image = pboxBugImage.Image;
using(var ms = new MemoryStream())
{
image.Save(ms, ImageFormat.Jpeg);
message.Attachments.Add(new Attachment(ms, "Screenshot.jpg"));
client.Credentials = new System.Net.NetworkCredential("credentials here");
client.Port = System.Convert.ToInt32(25);
client.Send(message);
}
new Endpage().Show();
this.Close();
}
catch
{
MessageBox.Show("my comment here");
}
}
Take a look at your resources and dispose the memorystream. I didnt for the example, because i wrote it here in editor

How to convert a HTML File to PDF using WkHTMLToSharp / wkhtmltopdf with Images in C#

I am generating HTML files on the fly, and I would like to create a PDF from the final file. I am using the following to generate the HTML file:
public static void WriteHTML(string cFile, List<Movie> mList)
{
int lineID = 0;
string strHeader, strMovie, strGenre, tmpGenre = null;
string strPDF = null;
// initiates streamwriter for catalog output file
FileStream fs = new FileStream(cFile, FileMode.Create);
StreamWriter catalog = new StreamWriter(fs);
strHeader = "<style type=\"text/css\">\r\n" + "<!--\r\n" + "tr#odd {\r\n" + " background-color:#e2e2e2;\r\n" + " vertical-align:top;\r\n" + "}\r\n" + "\r\n" + "tr#even {\r\n" + " vertical-align:top;\r\n" + "}\r\n" + "div#title {\r\n" + " font-size:16px;\r\n" + " font-weight:bold;\r\n" + "}\r\n" + "\r\n" + "div#mpaa {\r\n" + " font-size:10px;\r\n" + "}\r\n" + "\r\n" + "div#genre {\r\n" + " font-size:12px;\r\n" + " font-style:italic;\r\n" + "}\r\n" + "\r\n" + "div#plot {\r\n" + " height: 63px;\r\n" + " font-size:12px;\r\n" + " overflow:hidden;\r\n" + "}\r\n" + "-->\r\n" + "</style>\r\n" + "\r\n" + "<html>\r\n" + " <body>\r\n" + " <table>\r\n";
catalog.WriteLine(strHeader);
strPDF = strHeader;
foreach (Movie m in mList)
{
tmpGenre = null;
strMovie = lineID == 0 ? " <tr id=\"odd\" style=\"page-break-inside:avoid\">\r\n" : " <tr id=\"even\" style=\"page-break-inside:avoid\">\r\n";
catalog.WriteLine(strMovie);
strPDF += strMovie;
foreach (string genre in m.Genres)
tmpGenre += ", " + genre + "";
strGenre = tmpGenre != null ? tmpGenre.Substring(2) : null;
strMovie = " <td>\r\n" + " <img src=\".\\images\\" + m.ImageFile + "\" width=\"75\" height=\"110\">\r\n" + " </td>\r\n" + " <td>\r\n" + " <div id=\"title\">" + m.Title + "</div>\r\n" + " <div id=\"mpaa\">" + m.Certification + " " + m.MPAA + "</div>\r\n" + " <div id=\"genre\">" + strGenre + "</div>\r\n" + " <div id=\"plot\">" + m.Plot + "</div>\r\n" + " </td>\r\n" + " </tr>\r\n";
catalog.WriteLine(strMovie);
strPDF += strMovie;
lineID = lineID == 0 ? 1 : 0;
}
string closingHTML = " </table>\r\n" + " </body>\r\n" + "</html>";
catalog.WriteLine(closingHTML);
strPDF += closingHTML;
WritePDF(strPDF, cFile + ".PDF");
catalog.Close();
}
Once completed, I want to call the following function to generate the PDF file:
public static void WritePDF(string cFile, string pdfFile)
{
WkHtmlToPdfConverter w = new WkHtmlToPdfConverter();
byte[] strHTML = w.Convert(cFile);
File.WriteAllBytes(pdfFile, strHTML);
w.Dispose();
}
I've discovered that the .Convert function will convert HTML code to PDF, not a file. Secondly, when I pass in the HTML code directly, the images are not appearing in the PDF. I know there is an issue with .GIF files, but these are all .JPG files.
I've read a lot about how good wkhtmltopdf is, and the guy who wrote WkHTMLToSharp posted his project all over SO, but I've been disappointed by the lack of documentation for it.
I WANT to be able to pass in a file to convert, change the margins (I know this is possible, I just need to figure out the correct settings), have it convert images correctly, and most importantly, to not break up my items across multiple pages (support "page-break-inside:avoid" or something similar).
I'd love to see how others are using this!

I have coded an example about how to create a PDF from HTML. I just updated it to also print images.
https://github.com/hmadrigal/playground-dotnet/tree/master/MsDotNet.PdfGeneration
(In my blog post I explain most of the project https://hmadrigal.wordpress.com/2015/10/16/creating-pdf-reports-from-html-using-dotliquid-markup-for-templates-and-wkhtmltoxsharp-for-printing-pdf/ )
Pretty much you have two options:
1: Using file:// and the fullpath to the file.
<img alt="profile" src="{{ employee.PorfileFileName | Prepend: "Assets\ProfileImage\" | ToLocalPath }}" />
2: Using URL Data (https://en.wikipedia.org/wiki/Data_URI_scheme)
<img alt="profile" src="data:image/png;base64,{{ employee.PorfileFileName | Prepend: "Assets\ProfileImage\" | ToLocalPath | ToBase64 }}" />
Cheers,
Herb

Use WkHtmlToXSharp.
Download the latest DLL from Github
public static string ConvertHTMLtoPDF(string htmlFullPath, string pageSize, string orientation)
{
string pdfUrl = htmlFullPath.Replace(".html", ".pdf");
try
{
#region USING WkHtmlToXSharp.dll
//IHtmlToPdfConverter converter = new WkHtmlToPdfConverter();
IHtmlToPdfConverter converter = new MultiplexingConverter();
converter.GlobalSettings.Margin.Top = "0cm";
converter.GlobalSettings.Margin.Bottom = "0cm";
converter.GlobalSettings.Margin.Left = "0cm";
converter.GlobalSettings.Margin.Right = "0cm";
converter.GlobalSettings.Orientation = (PdfOrientation)Enum.Parse(typeof(PdfOrientation), orientation);
if (!string.IsNullOrEmpty(pageSize))
converter.GlobalSettings.Size.PageSize = (PdfPageSize)Enum.Parse(typeof(PdfPageSize), pageSize);
converter.ObjectSettings.Page = htmlFullPath;
converter.ObjectSettings.Web.EnablePlugins = true;
converter.ObjectSettings.Web.EnableJavascript = true;
converter.ObjectSettings.Web.Background = true;
converter.ObjectSettings.Web.LoadImages = true;
converter.ObjectSettings.Load.LoadErrorHandling = LoadErrorHandlingType.ignore;
Byte[] bufferPDF = converter.Convert();
System.IO.File.WriteAllBytes(pdfUrl, bufferPDF);
converter.Dispose();
#endregion
}
catch (Exception ex)
{
throw new Exception(ex.Message, ex);
}
return pdfUrl;
}

You can use Spire.Pdf to do so.
This component could convert html to pdf.
PdfDocument pdfdoc = new PdfDocument();
pdfdoc.LoadFromHTML(fileFullName, true, true, true);
//String url = "http://www.e-iceblue.com/";
//pdfdoc.LoadFromHTML(url, false, true, true);
pdfdoc.SaveToFile("FromHTML.pdf");

We're also using wkhtmltopdf and are able to render images correctly. However, by default the rendering of images is disabled.
You have to specify those options on your converter instance:
var wk = _GetConverter()
wk.GlobalSettings.Margin.Top = "20mm";
wk.GlobalSettings.Margin.Bottom = "10mm";
wk.GlobalSettings.Margin.Left = "10mm";
wk.GlobalSettings.Margin.Right = "10mm";
wk.GlobalSettings.Size.PaperSize = PdfPaperSize.A4;
wk.ObjectSettings.Web.PrintMediaType = true;
wk.ObjectSettings.Web.LoadImages = true;
wk.ObjectSettings.Web.EnablePlugins = false;
wk.ObjectSettings.Web.EnableJavascript = true;
result = wk.Convert(htmlContent);
