在U/I线程中处理了GetDataComplete?

问题描述

我可以假定始终在U/I线程中调用"GetDataComplete"的异步Web服务完成事件吗?在这种情况下，下面的代码是多余的.或者对于可能从另一个线程调用的方案很有帮助.

Can I assume that "GetDataComplete"''s async web service completed event is always invoked in the U/I thread? In which case the code below is redundant. Or is that good defense for scenarious where it may call from another thread.

var svc = new ServiceTest.Service1Client();
svc.GetDataCompleted += (o, evt) =>
{
    if (null == evt.Error)
    {
        Dispatcher.BeginInvoke(() =>
                                   {
                                       label1.Content
                                           = evt.Result;
                                   }
            );
    }
};

谢谢！

Thanks!
