按上数字键1如何样响应botton_click事件

按下数字键1怎么样响应botton_click事件
win mobile: 
  private void b_setTermNo_Click(object sender, EventArgs e)
  {
  setTermNo frm61 = new setTermNo();
  frm61.Show();
  }
  private void setTing_KeyPress(object sender, KeyPressEventArgs e)
  {
  //if (e.KeyChar == '1')
  //{
  // setTermNo frm61 = new setTermNo();
  // frm61.Show();
  //}
  if (e.KeyChar == '1')
  {
  b_setTermNo_Click
  }
  }

请问"if (e.KeyChar == '1')"这里的内容应该怎么样写? 


[解决办法]
b_setTermNo_Click(buuton1, EventArgs.Empty)
[解决办法]
b_setTermNo_Click(null, null);
