Send email with attachment from WinForms app?

I am currently using Process.Start to send simple emails from my WinForms app. Can you think of any way to add a file attachmen开发者_运维技巧t to the email? (Edit: using Process.Start?)

Here's what I use now:

Process.Start("mailto:test@test.invalid?subject=" + HttpUtility.HtmlAttributeEncode("Application error report") + "&body=" + body);

Try something like this -->

MailMessage theMailMessage = new MailMessage("from@email.com", "to@email.com");
theMailMessage.Body = "body email message here";
theMailMessage.Attachments.Add(new Attachment("pathToEmailAttachment"));
theMailMessage.Subject = "Subject here";

SmtpClient theClient = new SmtpClient("IP.Address.Of.Smtp");
theClient.UseDefaultCredentials = false;
System.Net.NetworkCredential theCredential = new System.Net.NetworkCredential("user@name.com", "password");
theClient.Credentials = theCredential;
theClient.Send(theMailMessage);

Alright, based on your edit and additional info, I found this Blog Post by Jon Galloway, "Sending files via the default e-mail client".

This looks like what you may be looking for, though I don't profess any knowledge with this way as I have always used the method I posted.

Hopefully it is of use to you.
