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WaitingForACtivation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
