在我的场景中中止线程的最佳方法是什么
如果其他人之前问过类似的问题，我很抱歉。 我有一个简单的 GUI 应用程序，它将一些文件上传到服务器。我把上传工作放在一个单独的线程中。当用户想要退出应用程序时，会设置一个事件来通知线程正常退出。然后UI线程会等待它。我用来中止线程的代码如下：-
if (mUploadThread != null) {
if (mStopUploadEvent.WaitOne(0, true)) {
string message = @"A normal cancellation may take a couple of minutes. Are you sure you want forcibly abort?";
string caption = @"Warning";
if (DialogResult.Yes == MessageBox.Show(message, caption, MessageBoxButtons.YesNo)) {
mUploadThread.Abort();
}
} else {
mStopUploadEvent.Set();
}
do {
Application.DoEvents();
} while (!mUploadThread.Join(1000));
}
这里，如果用户确实愿意，我想终止工作线程。但 abort() 方法不起作用。任何建议表示赞赏。
I'm sorry if some other people have asked a similar question before.
I have a simple GUI app which upload some files to a server. I put the upload work to a seperate thread. When users want to exit the application, a event will be set to notify the thread to exit normally. Then the UI thread will wait for it. The code I used to abort the thread is as follows:-
if (mUploadThread != null) {
if (mStopUploadEvent.WaitOne(0, true)) {
string message = @"A normal cancellation may take a couple of minutes. Are you sure you want forcibly abort?";
string caption = @"Warning";
if (DialogResult.Yes == MessageBox.Show(message, caption, MessageBoxButtons.YesNo)) {
mUploadThread.Abort();
}
} else {
mStopUploadEvent.Set();
}
do {
Application.DoEvents();
} while (!mUploadThread.Join(1000));
}
Here I want to terminate the worker thread if the user do want to. But the abort() method just doesn't work. Any suggestion is appreciated.

嗯，你上传得怎么样？
Thread.Abort很少是一个明智的选择 - 它可以让您的AppDomain（甚至Process）完全陷入困境。混乱的状态。如果您通过http上传，您可以尝试使用异步方法，允许您调用HttpWebRequest.Abort，这更友好一些。Well, how are you uploading?
Thread.Abortis rarely a sensible choice - it can leave youAppDomain(or evenProcess) in a completely messed-up state. If you are uploading via http, you could try using the async methods, allowing you to callHttpWebRequest.Abort, which is a bit more friendly.顺便说一句，这只是对马克所说的进行补充，这个答案可能有助于理解为什么
.Abort不是一个好的选择。Btw, this is just to add to what Marc said, this answer might help understand why
.Abortis not so a good choice.
