c# - Silverlight WCF 抛出远程服务器返回错误 : NotFound

Question

我想弄清楚为什么会这样。 super 奇怪

以下是我接到的确切电话。每当我在车辆数据契约(Contract)的末尾添加额外的数据时，我都会收到远程服务器返回的错误:NotFound。当调用 pick.SaveVehiclesAsync(infoKey, data);

从 Silverlight 端

public void SaveVehicles(InfoKey infoKey, ObservableCollection<VehicleFullInfoModel> vehicleFullInfoCollection, EventHandler<SaveVehiclesEventArgs> callBack)
    {
        var pick = new **ProjectServiceClient**();
        pick.SaveVehiclesCompleted += (sender, e) =>
        {
            if (callBack != null)
                callBack(this, new SaveVehiclesEventArgs(e.Result, e.fault));
        };
        var data =
            new ObservableCollection<VehicleFullInfo>(vehicleFullInfoCollection.Select(rec => rec.Data).ToList());
        pick.SaveVehiclesAsync(infoKey, data);
    }

------------ 来自 WCF 服务

public interface IProjectService
{
    [OperationContract]
    string SaveVehicles(InfoKey infoKey, IList<VehicleFullInfo> vehicleFullInfoCollection, out FaultContract fault);
}
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class ProjectService : IProjectService
{
    public string SaveVehicles(InfoKey infoKey, IList<VehicleFullInfo> vehicleFullInfoCollection, out FaultContract fault)
    {      
        return PickVehicles.SaveVehicles(infoKey, vehicleFullInfoCollection,  out fault);
    }
}

    public Vehicle Vehicle { get; private set; }

Not Found 是 Silverlight 上的一般错误，它可能意味着很多事情 - 跨域问题、来自网络的任何非 200 响应等。您可以做一些事情，例如在服务器端启用跟踪，或使用 Fiddler 等工具查看网络流量，这将为您提供有关错误的更多信息。
