诊断ObjectDisposedException"安全句柄已关闭"

Question

我有一个C#应用程序,它使用消息命中ObjectDisposedException

安全手柄已关闭

一旦我启动应用程序,就会发生这种情况.

可悲的是,堆栈跟踪真的没有用(见下文).有什么方法可以让我确定在这里异步尝试的呼叫是什么？

DoAsyncCall()是否真的意味着异步方法调用？

Answer 1

问题是由于我使用了using(){}块引起的.

    using (WaitHandle handle = asyncResponse.AsyncWaitHandle)
    {
      asyncResponse.AsyncWaitHandle.WaitOne();
      string response = asyncRequest.EndInvoke(asyncResponse);
      asyncResponse.AsyncWaitHandle.Close();
      return response;
    } 

当调用线程被中断时,using块仍然在WaitHandle上调用Close.

Answer 2

您正在处理仍由其他线程使用的内容.
