推荐答案

事件不是单向的，如果您正在调试和跟踪事件，事件会调用一个函数（接收者）以及完成调用的时间堆栈必须折叠回到事件触发例程。



我认为你的问题是，你是在不同的线程上在UI上进行交互（事件是产生的）在新线程中）。与事件中的表单交互将导致异常（事件被触发，而不是与UI交互的位置）。



为了与UI交互，如果表单上的InvokeRequired标志为true，则必须调用（使用Form.Invoke或Control.Invoke）方法控制。即使在打开新表单或设置现有控件或表单的属性时也是如此，否则可能会出现IllegalCrossThreadException或应用程序挂起。

Events are not one way, if you are debugging and tracing your events, the event calls a function (the receiver) and when it is finished the call stack MUST collapse back up to the event firing routine.

What I think your problem is, is that you are interacting on the UI from a different thread (events are spawned in new threads). Interacting with a form from an event will cause an exception (where the event is fired, not where you interact with the UI).

In order to interact with the UI, you have to invoke (using the Form.Invoke or Control.Invoke) methods if the InvokeRequired flag is true on the form or control. This is true even when opening new forms or setting properties of existing controls or forms, otherwise you can get an IllegalCrossThreadException or an application hang.
