Process is belongs to which namespace

any way I used this code:

private void Button1_Click(object sender, EventArgs e)
{
Help.ShowHelp(this, "Help.chm");
}

it worked.

System.Diagnostics namespace, for more please visit Process.Start Method (ProcessStartInfo) (System.Diagnostics).

As I understood his question, he doesn't want to show a help for his program, right
