在 wcf 服务中使用类接口作为参数 [英] using class interface as a parameter in wcf service

问题描述

我有 WCF 服务合同并使用类接口作为参数如下:

I Have WCF Service Contract and Using a class interface as a parameter as follow :

[ServiceContract(Name = "IFrameworkBaseService", CallbackContract = typeof(IFrameworkBaseServiceCallback))]
public interface IFrameworkBaseService
{
    [OperationContract]
    void InitializeConnection(IClientID clientID);
}

但我收到以下错误:

通信对象 System.ServiceModel.Channels.ServiceChannel 无法用于通信，因为它处于 Faulted 状态

谁能帮我解决这个问题

谢谢阿信

推荐答案

我认为您为 IClientID 传入的具体对象对服务来说是未知的.您必须使用 KnownType-Attribute

I think the concret object you passed in for the IClientID is just unknown to the service. You have to add it with KnownType-Attribute

[ServiceContract(Name = "IFrameworkBaseService", CallbackContract = typeof(IFrameworkBaseServiceCallback))]
[KnownType(typeof(MyClientId))]
public interface IFrameworkBaseService
{
    [OperationContract]
    void InitializeConnection(IClientID clientID);
}
