问题描述

我已经寻找了一段时间的代码，这些代码告诉我们鼠标单击了什么控件.我有一个包含50多个控件的窗体，并且我不想单击每个控件来使鼠标单击.我该怎么做?

I have been looking around for a while for some code that tells what control the mouse has clicked. I have a Form with over 50 controls and I don't want to click each one to make a mouse clicked on. How would I do this?

推荐答案

您可以使用每个控件的 Tag 属性.因此，将其设置为有意义的值，并在Click事件上执行以下操作:

You can use the Tag property of each control. So set it to something meaningful and on Click event do something like this:

(sender As Control).Tag

编辑:您也可以这样做:

foreach (Control item in this.Controls)     //this IS YOUR CURRENT FORM
{
    if ((sender as Control).Equals(item))
    {
        //Do what you want
    }
}
