无法打开默认邮件客户端

Question

I am using following code to open the default mail client

using (Process mailProcess = new Process())
{
     ProcessStartInfo processInfo = new ProcessStartInfo();
     processInfo.FileName = string.Format(CultureInfo.InvariantCulture, 
                            "mailto:{0}?subject={1}&body={2}", 
                             sendToAddress.Address, subject, message);
     processInfo.UseShellExecute = true;
     processInfo.WindowStyle = ProcessWindowStyle.Normal;
     mailProcess.StartInfo = processInfo;
     Process.Start(processInfo);
}

It starts the process but doesn't show mail client. Actually when I am using only localhost it doesn't open the mail client although it starts the process.

When I am using localhost: it works.

Can anybosy hel me?

Answer 1

This will start default email client

 var process = @"mailto:some.guy@someplace.com?subject=an email&body=see attachment";
 System.Diagnostics.Process.Start(process);

Answer 2

You can do it like this:

var url = string.Format(CultureInfo.InvariantCulture, 
                            "mailto:{0}?subject={1}&body={2}", 
                             sendToAddress.Address, subject, message);
Process.Start(url);

You have to use System.Diagnostics;
