您可以使用窗体的的 Controls.Find（）方法来检索参考后面：

You can use the form's Controls.Find() method to retrieve a reference back:

        var matches = this.Controls.Find("button2", true);

要注意的是这个返回的阵列的，控件的名称属性可以是模糊的，没有机制可确保控件具有唯一的名称。你必须强制自己。

Beware that this returns an array, the Name property of a control can be ambiguous, there is no mechanism that ensures that a control has a unique name. You'll have to enforce that yourself.
