Open email client in C#


I want to be able to open an email client with the click of a button, such as Outlook etc…

And prepopulate it with some text…

Is this possible?

I tried doing this:

    protected void Button1_Click(object sender, EventArgs e)
        System.Diagnostics.Process.Start("mailto:email@add ress?subject=my subject");

On button click, but it didnt work. I get the following error:

The parameter is incorrect

I need to be able to prepopulate the body of the message… Can anyone help?
