c# textbox只能输入数字和回车符（ctrl+c，ctrl+v）

 private void tbxStationID_KeyPress(object sender, KeyPressEventArgs e)
        {
            if ((e.KeyChar >= 48 && e.KeyChar <= 57) || (e.KeyChar >= 64 && e.KeyChar <= 123) || e.KeyChar == 8 || e.KeyChar == 3 || e.KeyChar == 22 || e.KeyChar == ',')
            {
                e.Handled = false;
            }
            else
            {
                e.Handled = true;
            }
        }
