在Universal应用程序中调用WCF服务

Question

我试图在Windows通用应用程序中调用WCF服务，显然你只能异步调用函数“GetMoments”。但我无法填写ObservableCollection。

EndpointAddress address = new EndpointAddress("net.tcp://localhost:9999/DeliveryService");

NetTcpBinding binding = new NetTcpBinding(SecurityMode.None);

DeliveryClient client = new DeliveryClient(binding, address);

Task<ObservableCollection<DeliveryMoment>> moments = client.GetMomentsAsync();

moment.Wait（）只是永远等待并调用moment.Start（）是不允许的，这会引发异常。如何填写收藏品？

Answer 1

请你用await / async模式进行测试吗？例如：

public async void Load()
{
      EndpointAddress address = new EndpointAddress("net.tcp://localhost:9999/DeliveryService");

      NetTcpBinding binding = new NetTcpBinding(SecurityMode.None);

      DeliveryClient client = new DeliveryClient(binding, address);

      ObservableCollection<DeliveryMoment> moments = await client.GetMomentsAsync();
}
