I am trying to compose a email that has a body with a embedded image using LinkedResource. When I try to Post it to our api that connects to the smtp I get this exception:
System.AggregateException: InvalidOperationException: Timeouts are not supported on this stream.
JsonSerializationException: Error getting value 'ReadTimeout' on 'System.IO.FileStream'.
This is my code what do I need to change to make this work.
class Program
{
static void Main(string[] args)
{
Mailer();
}
public static void Mailer()
{
var imageOne = new LinkedResource("PumpkinSpice.jpg", "image/jpeg");
imageOne.ContentId = "psl";
var imageLink = $"<img src=\"cid:{imageOne.ContentId}\"/>";
var listOfResources = new List<LinkedResource> {imageOne};
var email = new MailInfo()
{
ToAddresses = "mcjibbles#foo.com",
CcAddresses = "jibbles#bar.com",
BccAddresses = null,
Subject = "test email",
Body = "Email body" + imageLink,
Resources = listOfResources,
IsHtml = true
};
using (var client = CreateClient())
{
client.PostAsJsonAsync($"api/email", email).Wait();
}
}
private static HttpClient CreateClient()

When I am trying to upload a file using following code I am receiving Length Required error. Please note that if I am uploading a TEXT file then I don't see any issues.

Tried to use HttpRequestMessage by setting Content-Length but again able to upload TEXT files but not WORD or PDF files.
I am trying to read and write a value on appsettings.json.It is called Refreshed_Token. I have found something on internet and it was very well explained as an example but i get only one error. Can you please guys help me thank you very much.
Worker.cs

var request = new RestRequest();
request.AddHeader("Cookie", "xxx; xxx; iamcsr=xxx");
RestResponse response = await client.PostAsync(request);
var result = JObject.Parse(response.Content);
var refresh_token = result["refresh_token"].Value<string>();
update_appsettings_json(refresh_token);
}

I am using a method to try and iterate through an object to get all of the object's properties, some of which are lists of objects.
This all works except for the part where I check for objects within the initial object's properties. If it finds a list of objects I want it to iterate through them.
Annoyingly, I'm getting null on my list of whatever type.
I'm now getting an error in VS because pt isn't instantiated, but it would be at run time.
Below is the if statement I'm using to try and catch whatever object/List is being parsed.
Am I going the right (roundabout) way or doing this or is this completely wrong?
Problematic Code - if statement null list:
public static string DeconstructLists<T>(T obj, string body)
{
Type type = obj.GetType();
PropertyInfo[] properties = type.GetProperties();
foreach (PropertyInfo property in properties)
{
if (property.PropertyType == typeof(string) || property.PropertyType == typeof(int) || property.PropertyType == typeof(bool))
body += property.Name + " = " + property.GetValue(obj, null) + Environment.NewLine;
else
{
if (typeof(IEnumerable).IsAssignableFrom(property.PropertyType))
{
//null list exception
var list = (IEnumerable)property.GetValue(obj, null);
foreach (var item in list)
{
DeconstructLists(item, body);
}
// stack overflow exception
//var props = property.PropertyType.GetGenericArguments()[0];
//foreach (var p in props.GetProperties())
//{
// DeconstructLists(p, body);
//}
}
}
}
return body;
}
Post create method:
public ActionResult Create(Company cmp)
{
if (ModelState.IsValid)
{
db.companys.Add(cmp);
db.SaveChanges();
// send email
SendEmail(cmp);
return RedirectToAction("Thankyou", "Home", new { form="ASN" });
}
return View(cmp);
}
Send email method:
public static void SendEmail(Company cm)
{
string _body = "";
string _subject = "ASN Form Request";
_body = DeconstructLists<Company>(cm, _body);
using (SmtpClient msgClient = new SmtpClient())
{
msgClient.EnableSsl = false;
msgClient.DeliveryMethod = SmtpDeliveryMethod.Network;
msgClient.UseDefaultCredentials = false;
msgClient.Credentials = new NetworkCredential
{
UserName = "",
Password = ""
};
msgClient.Host = "";
msgClient.Port = 0;
using (MailMessage msg = new MailMessage())
{
msg.To.Add(""); // to add
msg.From = new MailAddress("");// from add
msg.Subject = _subject;
msg.Body = _body;
// preparing the message to be sent
msgClient.Send(msg);
}
}
}
Class objects:
public class Company
{
public int companyId { get; set; }
public string name { get; set; }
public string telephone { get; set; }
public string regNumber { get; set; }
public virtual IList<Asn> asns { get; set; }
public virtual IList<Contact> contacts { get; set; }
}
public class Contact
{
public int contactId { get; set; }
public int companyId { get; set; }
public Company company { get; set; }
public string name { get; set; }
public string telephone { get; set; }
}
public class Asn
{
public int asnId { get; set; }
public int companyId { get; set; }
public Company company { get; set; }
public bool userBehalf { get; set; }
public bool something { get; set; }
}
If it finds a list of objects I want it to iterate through them.
You don't need a list for iteration, the minimum iteratable type is IEnumerable. In fact your if statement is checking just that
if (typeof(IEnumerable).IsAssignableFrom(property.PropertyType))
{
// ...
}
So why not just using inside
var list = (IEnumerable)property.GetValue(obj, null);
foreach (var item in list)
{
DeconstructLists(item, body);
}
EDIT: See this, it works, then see why yours does not:
using System;
using System.Collections;
using System.Collections.Generic;
namespace Tests
{
class Test
{
static void Main(string[] args)
{
var company = new Company
{
companyId = 1,
name = "ACME",
};
company.asns = new List<Asn>
{
new Asn { asnId = 1, companyId = company.companyId, company = company },
new Asn { asnId = 2, companyId = company.companyId, company = company },
};
company.contacts = new List<Contact>
{
new Contact { contactId = 1, companyId = company.companyId, company = company, name = "Contact1" },
new Contact { contactId = 2, companyId = company.companyId, company = company, name = "Contact2" }
};
var body = DeconstructLists(company, "");
}
public static string DeconstructLists<T>(T obj, string body)
{
var type = obj.GetType();
var properties = type.GetProperties();
foreach (var property in properties)
{
if (property.PropertyType == typeof(string) || property.PropertyType == typeof(int) || property.PropertyType == typeof(bool))
body += property.Name + " = " + property.GetValue(obj, null) + Environment.NewLine;
else
{
if (typeof(IEnumerable).IsAssignableFrom(property.PropertyType))
{
body = body + property.Name + ": {" + Environment.NewLine;
var list = (IEnumerable)property.GetValue(obj, null);
foreach (var item in list)
{
body = body + item.GetType().Name + ": {" + DeconstructLists(item, "") + "}" + Environment.NewLine;
}
body = body + "}" + Environment.NewLine;
}
}
}
return body;
}
}
public class Company
{
public int companyId { get; set; }
public string name { get; set; }
public string telephone { get; set; }
public string regNumber { get; set; }
public virtual IList<Asn> asns { get; set; }
public virtual IList<Contact> contacts { get; set; }
}
public class Contact
{
public int contactId { get; set; }
public int companyId { get; set; }
public Company company { get; set; }
public string name { get; set; }
public string telephone { get; set; }
}
public class Asn
{
public int asnId { get; set; }
public int companyId { get; set; }
public Company company { get; set; }
public bool userBehalf { get; set; }
public bool something { get; set; }
}
}
Maybe you could try something like this in your if statement ?
var genericType = property.PropertyType.GetGenericArguments()[0];
foreach (var prop in genericType.GetProperties())
{
DeconstructLists(prop, body);
}

managed to get it working by changing the content-type to :
_webClient.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
i was debugging with charles and the python version was posting a json formated form, changed the c# content type to match and now works a treat
Many Thanks for your code and help.
