如何激活在C＃中的任务吗？ [英] How to activate task in c#?

问题描述

我'试图消耗在Windows 8一个WCF：
我的code消耗由WCF服务生成的方法：

I'am trying to consume a wcf in windows 8: My code to consume the method generated by the WCF service:

public System.Threading.Tasks.Task<Maquette_MyAirport_Win8.FlightService.CitiesResponse> 
    GetAllCitiesAsync(Maquette_MyAirport_Win8.FlightService.BaseRequest request)
{
    return base.Channel.GetAllCitiesAsync(request);
}

是

public testproxy()
{
    _client = new FlightInfoServiceClient(Maquette_MyAirport_Win8.FlightService.FlightInfoServiceClient.EndpointConfiguration.wsHttpBindingConfiguration);
    BaseRequest req = new BaseRequest();
    System.Threading.Tasks.Task<Maquette_MyAirport_Win8.FlightService.CitiesResponse> CitiesResponse = _client.GetAllCitiesAsync( new BaseRequest());
    CitiesResponse.ContinueWith(task => citiesL = task.Result.Cities.FirstOrDefault(););

}

任务citiesResponse的状态为WaitingForACtivati​​on的结果=还没有已计算

The status of the task citiesResponse is "WaitingForACtivation" and Result="Not yet Computed"

我怎样才能激活任务，我怎么能得出结果??

How can I Activate the task and how can i obtain the result??

推荐答案

你没有添加异步并等待得到的结果类型，而不是任务类型??

Don't you have to add async and await to get the result type instead of Task type??

应该是这样的：

var result = await _client.GetAllCitiesAsync( new BaseRequest());

而在方法，你应该添加异步

And in the method you should add async
