推荐答案

如果我理解你的问题，你想从外面访问用户控件里面的控件。



如果这是我强烈建议不要这样做。如果需要从外部影响控制行为或从中读取信息，请在控件中定义属性和方法。如果您需要接收通知，请在用户控件中定义事件。



创建用户控件时的一个好原则是，从外部您不需要知道控件是什么实际上包含或如何工作。如上所述，你只需要有意义与之沟通。



看看例如创建Windows窗体用户控件 [ ^ ]。即使它是VB而且相当陈旧，它解释了第一步。

If I understand your question correctly, you want to access the controls inside a user control from outside.

If this is the case I would strongly advice not to do so. If you need to affect the control behaviour from outside or read information from it, define properties and methods in the control. If you need to receive notifications, define events in the user control.

One good principle when creating user controls is that from outside you should not need to know what the control actually contains or how it works. You just need to have meanings to communicate with it as described above.

Have a look at for example Creating a Windows Form User Control[^]. Even though it's VB and rather old it explains the first steps.
