我工作的一个多线程的Silverlight应用程序。

I'm working on a multi-threaded Silverlight application.

应用程序有两个线程：主/用​​户界面和后台工作线程

The application has two threads: Main/UI and a background working thread.

在UI线程应该能够杀死后台线程，就像这样：

The UI thread should be able to kill the background thread, like so:

private Thread executionThread;

....

executionThread = new Thread(ExecuteStart);
executionThread.Start();

....

executionThread.Abort(); // when the user clicks "Stop"

最后一行抛出一个异常：

The last line raises an Exception:

MethodAccessException：尝试访问该方法失败：System.Threading.Thread.Abort（）

MethodAccessException: Attempt to access the method failed: System.Threading.Thread.Abort()

你知道吗？为什么我不能中止线程在Silverlight？

Any idea? why i cannot abort a thread in Silverlight?

谢谢， 纳伊米

推荐答案

而不是为了这个目的手动创建一个线程，你可能要考虑使用的 BackgroundWorker的类。

Rather than creating a Thread manually for this purpose you might want to consider using the BackgroundWorker class.

本类具有内置的功能来取消异步操作时WorkerSupportsCancellation =真。

This class has built in functionality for cancelling the asynchronous operation when WorkerSupportsCancellation = true.

有一个看看这篇文章在MSDN上的全如何使用BackgroundWorker的在Silverlight例如。

Have a look at this article on MSDN for a full example of how to use the BackgroundWorker in Silverlight.
