c# - 如何防止此异常：值不在预期范围内。使用 WaitHandle.WaitAny 方法？

Question

QueueCompareProcessThread() 异常消息：值不在预期范围内。跟踪：在 System.Threading.WaitHandle.WaitAny(WaitHandle[] waitHandles, Int32 毫秒Timeout, Boolean exitContext) 在 System.Threading.WaitHandle.WaitAny(WaitHandle[] waitHandles, Int32 millisecondsTimeout, Boolean exitContext) 在 System.Threading. WaitHandle.WaitAny(WaitHandle[] waitHandles)

当我在线程中使用该WaitAny方法时，出现上述异常。WaitHandle请帮我解决问题。这是我的部分代码：

public void QueueCompareProcessThread(QueueProcesses Qp)
{
    try
    {
        WaitHandle[] pHandles = Qp.GetRunningProcessesHandles();
        WaitHandle.WaitAny(pHandles);
        Qp.RemoveExitedProcess();   // clearing the process list 
        // strange behavior is while clearing the process list i'm getting the exception in the thread Waitany method
        // Does Waitany method still working after it returns?
    }
    catch (Exception e)
    {
        utils.Log("QProc Exception at QueueCompareProcessThread() Message:" + e.Message + " Trace:" + e.StackTrace);
    }
}

谁能提供一些关于 WaitAny 方法的想法并帮助我解决问题？
