如何获取线程执行完成事件 [英] How to get thread execution complete event

问题描述

我正在创建一个新线程以在其中调用函数.

I am creating a new thread to call a function in it.

Thread th = new Thread(My_Function);
th.start();

我想在此线程执行完成时做些事情.

I wanna do something on completion of this thread execution.

有什么办法吗?

推荐答案

至少两个可能的解决方案:

At least two possible solutions:

BackgroundWorker

使用 BackgroundWorker 执行您的代码，然后使用 RunWorkerCompleted 事件，以执行在完成后运行的代码.

Use a BackgroundWorker to execute your code, and use the RunWorkerCompleted event to execute the code that is run after completion.

A BackgroundWorker将基于事件的异步模式包装到一个非常易于使用的机制中，并带有进度报告和取消功能.请参见 BackgroundWorker教程和<一个href ="https://stackoverflow.com/questions/6481304/how-to-use-a-backgroundworker">此 SO答案.

A BackgroundWorker wraps the event based asynchronous pattern into a very easy to use mechanism, complete with progress reporting and cancellation. See this BackgroundWorker tutorial and this SO answer .

任务(.NET 4.0及更高版本)

使用 Task 对象，然后使用 ContinueWith 方法，用于定义在完成第一个任务后需要执行的代码.

Use a Task object, and use the ContinueWith method to define the code that needs to be executed after completion of the first task.
