在我完成这项任务之后,我准备向使用非洲复兴开发银行的客户提供最新情况时,我有了一个缓慢的任务。 在我的客户中,我多次呼吁更新成果网。 为了了解情况,其联系人通过联系清单证明他们是否活着。

I have implemented the service as WCF. I generate async methods when I add the service reference to my web client.

The code works fine, however the screen locks momentarily when the callbacks fire - I think this is because they all happen one after the other and all of them repaint the GridView within quick succession. I don t want this glitch to happen -I was hoping the AJAX implementation would be able to partially update the GridView as results come back from the service via the callbacks.

The only way I can make this look nice is to launch the async calls in a separate client thread and then use a timer to repaint the data to the grid (the same data that s being updated in the separate thread via the callbacks).

我将这一微型项目作为学习练习,然后我与MVC3一样了解差异。

• 《Snippet法典》(没有单独校对,导致在警示期间减慢的屏幕):

//get list of connections from session
ConnectionList myConns = Session[SESSION_ID] as ConnectionList;
//pass into async service call
GetAllStatusAsync(myConns);


protected void GetAllStatusAsync(ConnectionList myConns)
{

Service1Client myClient = new WcfConnectionServiceRef.Service1Client();
myClient.AsyncWorkCompleted += new EventHandler<AsyncWorkCompletedEventArgs>(myClient_AsyncWorkCompleted);

foreach (ConnectionDetail conn in myConns.ConnectionDetail)
  {
  //this call isnt blocking, conn wont be updated until later in the callback
  myClient.AsyncWorkAsync(conn);
  }
}

//callback method from async task
void myClient_AsyncWorkCompleted(object sender, AsyncWorkCompletedEventArgs e)
{

ConnectionDetail connResult = e.Result;

//get list of connections from session
ConnectionList myConns = Session[SESSION_ID] as ConnectionList;

//update our local store
UpdateConnectionStore(connResult, myConns);

//rebind grid
BindConnectionDetailsToGrid(myConns);

}

问题在于——能否以更好的方式来做到这一点? (为了避免造成问题,随着结果的产生,使电网得到部分更新)我实际上不想使用单独的客户线,如以下幻灯:

 // Perform processing of files async in another thread so rendering is not slowed down 
 // this is a fire and forget approach so i will never get results back unless i poll for them in timer from the main thread
ThreadPool.QueueUserWorkItem(delegate
  {
  //get list of connections from session
  ConnectionList myConns = Session[SESSION_ID] as ConnectionList;
  //pass into async service call
  GetAllStatusAsync(myConns);
  });

我期待着一个简明的客户方联合倡议的例子。 收到的选择是好的,非常受赞赏,但委托方共同提交书面材料是我自己不per的,将为此给予回报。
