how can i kill a explore.exe automatically by using a sample?

foreach(Process p in Process.GetProcesses())
{
    try
    {
        //compare it with "explorer "
        if (p.MainModule.ModuleName.Contains("explorer") == true)
            p.Kill();
    }
    catch (Exception e)
    {
        //do some exception handling here
    }
    //restart explorer
    Process.Start("explorer.exe");
}
