C# Stop-Process command of PowerShell

[mewoooooo]

I want to use Stop-Process command (of PowerShell) in c#. I know how to use "Get-Process" command, But in the case of stop-process we have to give arguments(process name). In my case I am taking arguments from user in textbox.

  private void button2_Click(object sender, EventArgs e)
  {
    PowerShell ps = PowerShell.Create();

    ps.AddCommand("Stop-Process -Name " + (textBox1.Text).ToString());


    ps.Invoke();
  }
