C# MailTo with Attachment?

Question

Currently I am using the below method to open the users outlook email account and populate an email with the relevant content for sending:

public void SendSupportEmail(string emailAddress, string subject, string body)
{
   Process.Start("mailto:" + emailAddress + "?subject=" + subject + "&body=" 
                + body);
}

I want to however, be able to populate the email with an attached file.

something like:

public void SendSupportEmail(string emailAddress, string subject, string body)
{
   Process.Start("mailto:" + emailAddress + "?subject=" + subject + "&body=" 
      + body + "&Attach="
      + @"C:Documents and SettingsAdministratorDesktopstuff.txt");
}

However this does not seem to work. Does anyone know of a way which will allow this to work!?

Help greatly appreciate.

Regards.

If you want to access the default email client then you can use MAPI32.dll (works on Windows OS only). Take a look at the following wrapper:

http://www.codeproject.com/KB/IP/SendFileToNET.aspx

Code looks like this:

MAPI mapi = new MAPI();
mapi.AddAttachment("c:\temp\file1.txt");
mapi.AddAttachment("c:\temp\file2.txt");
mapi.AddRecipientTo("[email protected]");
mapi.AddRecipientTo("[email protected]");
mapi.SendMailPopup("testing", "body text");

// Or if you want try and do a direct send without displaying the mail dialog
// mapi.SendMailDirect("testing", "body text");
