There is no managed alternative to that but you can easily P/Invoke with:

[DllImport("user32.dll", CharSet = CharSet.Auto)]
static extern IntPtr SendMessage(IntPtr hWnd, UInt32 Msg, IntPtr wParam, IntPtr lParam);

private void button1_Click(object sender, EventArgs e)
{
    SendMessage(this.Handle, COMMAND_HERE, PARAM_HERE, 0);
}
