推荐答案

/// <summary>
/// Event to indicate UserControl Button Clicked
/// </summary>
public event EventHandler Clicked;
/// <summary>
/// Called to signal to subscribers that UserControl Button Clicked
/// </summary>
/// <param name="e"></param>
protected virtual void OnClicked(EventArgs e)
    {
    EventHandler eh = Clicked;
    if (eh != null)
        {
        eh(this, e);
        }
    }
private void button1_Click(object sender, EventArgs e)
    {
    OnClicked(e);
    }

您可以在UserControl中处理自己的事件（但为什么你想要的是另一件事）。只需在构造函数中为上面创建的事件添加处理程序：

You can handle your own events within the UserControl (but why you would want to is another thing). Just add a handler for the event you created above in your constructor:

Clicked += new EventHandler(MyUserControl_Clicked);
    ...
    }

void MyUserControl_Clicked(object sender, EventArgs e)
    {
    ...
    }

如果这不包括您要尝试的内容你需要更详细地解释一下。

If this doesn't cover what you are trying to do, you need to explain in better detail.
