Email configuration

Hi guys I am doing email function for the first time and I searched up on how to do a email
try
{
MailMessage message = new MailMessage();
SmtpClient smtp = new SmtpClient();
message.From = new MailAddress("from#gmail.com");
message.To.Add(new MailAddress("to#gmail.com"));
message.Subject = "Test";
message.Body = "Content";
smtp.Port = 587;
smtp.Host = "gmail.com";
smtp.EnableSsl = true;
smtp.UseDefaultCredentials = true;
smtp.Credentials = new NetworkCredential("from#gmail.com", "password");
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.Send(message);
}
catch (Exception ex)
{
MessageBox.Show("err: " + ex.Message);
}
I tried running this but I am not sure what is the problem... i did not use IIS or anything
(update)
I uploaded the error image in this website

This one will Help you..! try this..!
try

// Recipient e-mail address.
Msg.To.Add(to#gmail.com);
//here you can pass textbox value how need to send mail.
Msg.Subject = "Please confirm your subscription";
Msg.Body = "<body></body>";
Msg.IsBodyHtml = true;
// your remote SMTP server IP.

//Msg = null;

A first chance exception of type 'System.InvalidOperationException' occurred in System.dll [duplicate]

I can't understand why this code is not working. I get an error saying property can not be assigned
MailMessage mail = new MailMessage();
SmtpClient client = new SmtpClient();
client.Port = 25;
client.DeliveryMethod = SmtpDeliveryMethod.Network;

mail.To = "user#hotmail.com"; // <-- this one
mail.From = "you#yourcompany.example";
mail.Subject = "this is a test email.";
mail.Body = "this is my test email body";
client.Send(mail);

mail.To and mail.From are readonly. Move them to the constructor.
using System.Net.Mail;
...
MailMessage mail = new MailMessage("you#yourcompany.example", "user#hotmail.com");
SmtpClient client = new SmtpClient();
client.Port = 25;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Host = "smtp.gmail.com";
mail.Subject = "this is a test email.";
mail.Body = "this is my test email body";
client.Send(mail);

This :
mail.To = "user#hotmail.com";
Should be:
mail.To.Add(new MailAddress("user#hotmail.com"));

Finally got working :)

First go to https://myaccount.google.com/lesssecureapps and make Allow less secure apps true.
Then use the below code. This below code will work only if your from email address is from gmail.
static void SendEmail()
{
string mailBodyhtml =
"<p>some text here</p>";
var msg = new MailMessage("from#gmail.com", "to1#gmail.com", "Hello", mailBodyhtml);
msg.To.Add("to2#gmail.com");
msg.IsBodyHtml = true;
var smtpClient = new SmtpClient("smtp.gmail.com", 587); //**if your from email address is "from#hotmail.com" then host should be "smtp.hotmail.com"**
smtpClient.UseDefaultCredentials = true;
smtpClient.Credentials = new NetworkCredential("from#gmail.com", "password");
smtpClient.EnableSsl = true;
smtpClient.Send(msg);
Console.WriteLine("Email Sent Successfully");
}

If you want to have your email and password not appear in your code and want your company email client server to use your windows credentials use below.
client.Credentials = CredentialCache.DefaultNetworkCredentials;

C# Windows Form Application - Send email using gmail smtp

I have been trying to create a small program to send email through smtp.gmail.com, but it always prompt me that "The operation has timed out".
I know there are lots of solutions available on the net but none of it works.
try
{
MailMessage message = new MailMessage();
SmtpClient smtp = new SmtpClient();
message.From = new MailAddress("from#gmail.com");
message.To.Add(new MailAddress("to#gmail.com"));
message.Subject = "Test";
message.Body = "Content";
smtp.Port = 465;
smtp.Host = "smtp.gmail.com";
smtp.EnableSsl = true;
smtp.UseDefaultCredentials = false;
smtp.Credentials = new NetworkCredential("from#gmail.com", "pwd");
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.Send(message);
}
catch (Exception ex)
{
MessageBox.Show("err: " + ex.Message);
}
Is there any way to solve this?

Change the port to 587:
try
{
MailMessage message = new MailMessage();
SmtpClient smtp = new SmtpClient();
message.From = new MailAddress("from#gmail.com");
message.To.Add(new MailAddress("to#gmail.com"));
message.Subject = "Test";
message.Body = "Content";
smtp.Port = 587;
smtp.Host = "smtp.gmail.com";
smtp.EnableSsl = true;
smtp.UseDefaultCredentials = false;
smtp.Credentials = new NetworkCredential("from#gmail.com", "pwd");
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.Send(message);
}
catch (Exception ex)
{
MessageBox.Show("err: " + ex.Message);
}

you can use SMTP protocol to send this image as an Attachment, your code will be something like that :
using MailKit.Net.Smtp; using MimeKit;
MimeMessage message = new MimeMessage();
BodyBuilder Attachmint = new BodyBuilder();
message.From.Add(new MailboxAddress("name sender", "Mail From"));
message.To.Add(MailboxAddress.Parse("Mail To"));
message.Subject = Subject;
message.Body = new TextPart("plain")
{
Text = tex_body.Text + Massage
};
Attachmint.Attachments.Add("Attatchment Path");
message.Body = Attachmint.ToMessageBody();
SmtpClient client = new SmtpClient();
client.Connect("smtp.gmail.com", 465, true);
client.Authenticate("Mail from", "Password mail");
client.Send(message);

here's my C# code:

string to = "aevalencia191#gmail.com"; //Replace this with the Email Address to whom you want to send the mail
System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();
mail.To.Add(to); mail.From = new

mail.BodyEncoding = System.Text.Encoding.UTF8;
mail.IsBodyHtml = true ; mail.Priority = MailPriority.High;
SmtpClient client = new SmtpClient(); //Add the Creddentials- use your own email id and password
client.Credentials = new System.Net.NetworkCredential(from, "iseedeadpoeple");
client.Port = 587; // Gmail works on this port client.Host ="smtp.gmail.com";
client.EnableSsl = true; //Gmail works on Server Secured Layer
try

client.Send(mail);
}
catch (Exception ex)
{
Exception ex2 = ex;
string errorMessage = string.Empty;
while (ex2 != null)
{
errorMessage += ex2.ToString();
ex2 = ex2.InnerException;
} HttpContext.Current.Response.Write(errorMessage
);
} // end try
here's the error:
The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required.

You need to get and send mail to GMail by using SSL secutiry certificate
MailMessage msgMail = new MailMessage("a#gmail.com", "b#mail.me", "subject", "message body");
SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587);
smtp.EnableSsl = true;
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.Credentials = new System.Net.NetworkCredential("a#gmail.com", "a");
try
{
smtp.Send(msgMail);
}
catch (Exception ex)
{
}
