process standardoutput

[Lin]

Hi,

I am trying to open the client default email email application using
Process, then try to write email body using standardoutput, but it
doesn't work. My code as the following:

System.Diagnostics.Process p = new System.Diagnostics.Process();

System.Diagnostics.ProcessStartInfo psI = new
System.Diagnostics.ProcessStartInfo();
psI.UseShellExecute = false;
psI.RedirectStandardError = true;
psI.RedirectStandardInput = true;
psI.RedirectStandardOutput = true;
psI.FileName = "mailto:myemail@company?subject=my
subject";
p.StartInfo = psI;
p.Start();
StreamWriter sw = p.StandardInput;
sw.AutoFlush = true;

sw.Write("write to email body.");
sw.WriteLine(sw.NewLine);
sw.Close();

please help.

Thank you in advance.
