我有这段代码,看起来很简单,但 AutoResetEvent 永远不会收到信号。Web 服务似乎没有返回任何内容,并且 WaitAll 仅在 10 秒后超时。没有线程 jiggerypokery 一切正常,所以它不是 Web 服务问题。我究竟做错了什么?
AutoResetEvent[] autoEvents;
ObservableCollection<Tx3.ResourceService.ResourceTime> resourceTime;
ObservableCollection<Tx3.ResourceService.ResourceTimeDetail> resourceTimeDetail;
private void UserControl_Loaded(object sender, RoutedEventArgs e)
{
autoEvents = new AutoResetEvent[]
{
new AutoResetEvent(false),
new AutoResetEvent(false),
};
var resourceService = getResourceServiceClient();
// Get ResourceTime data for this user
resourceService.ListResourceTimeAsync(CategoryWorkItemId, ResourceId);
resourceService.ListResourceTimeCompleted += new EventHandler<Tx3.ResourceService.ListResourceTimeCompletedEventArgs>(resourceService_ListResourceTimeCompleted);
// Get ResourceTimeDetails
resourceService.ListResourceTimeDetailAsync(CategoryWorkItemId, ResourceId);
resourceService.ListResourceTimeDetailCompleted += new EventHandler<ListResourceTimeDetailCompletedEventArgs>(resourceService_ListResourceTimeDetailCompleted);
WaitHandle.WaitAll(autoEvents, 10000);
System.Diagnostics.Debug.WriteLine("do something with both datasets");
}
void resourceService_ListResourceTimeCompleted(object sender, Tx3.ResourceService.ListResourceTimeCompletedEventArgs e)
{
resourceTime = e.Result;
autoEvents[0].Set();
}
void resourceService_ListResourceTimeDetailCompleted(object sender, ListResourceTimeDetailCompletedEventArgs e)
{
resourceTimeDetail = e.Result;
autoEvents[1].Set();
}
