Answer 1

您可以通过比较sender参数：

来辨别按下了哪个按钮

void MyButton_Click(object sender, EventArgs e) 
{ 
    if (sender == MyButton1)
    {
        // 1st image button was clicked — some values
    }
    else if (sender == MyButton2)
    {
        // 2nd one was clicked — show another
    }
}

Answer 2

你不能创建2个事件和一个功能吗？例如：

//Hook both OnClick events to these!    
private void OnButton1Click(object sender, EventArgs e) { BeenClicked(button1); }
private void OnButton2Click(object sender, EventArgs e) { BeenClicked(button2); }

private void BeenClicked(Button ClickedButton) 
{
    if(ClickedButton.Text == Button1) Console.WriteLine("Hi to you too!"); 
}

或者您也可以使用：

//Hook both OnClick events to this!
private void OnButtonClick(object sender, EventArgs e) 
{ 
    ClickedButton = (Button)sender; 
    if(ClickedButton.Text == Button1) Console.WriteLine("Hi to you too!"); 
}

如果我理解你的话：）
