标签数组的事件句柄 [英] Event handle for array of labels

问题描述

在Windows窗体中，我有一系列标签。这些在整个计划中处于不同的位置。此外，没有指定的金额 - 它们是在运行时创建的，金额取决于用户点击的内容。



我有一个鼠标悬停事件，他们都链接到。但是，我不知道如何找出鼠标悬停在哪个标签上。你能以某种方式访问​​哪个控件发送事件？



我试过发件人 - >但没有任何结果我可以看到... ...



非常感谢。

In windows forms, I have an array of labels. These are in different positions throughout the program. Furthermore, there is not a specified amount - they are created during run time, with the amount depending on what the user clicks.

I have a mouse hover event, which they all link to. However, I dont know how to find out which label the mouse is hovering over. Can you somehow access which control is sending the event?

I tried sender-> but nothing comes up I can see a use for...

Many thanks.

推荐答案

Cast将sender参数转换为Control，它将为您提供使用控件的所有方法和属性的可能性。

Cast the "sender" argument into a Control and that will give you the possiblity of using all the methods and properties of a control.

Control ctrl = (Control) sender;
