WCF OperationContract与对象类型的参数

Question

我通过服务和数据合同在Windows应用程序中托管WCF服务

[ServiceContract]
[FaultContract(typeof(object))]
[ServiceKnownType(typeof(busSample))]
public interface IUPSBusinessTier
{

    [OperationContract]
    string TestMethod1(string astrName);

    [OperationContract]
    void TestMethod2(busSample abusSample);

    [OperationContract]
    busSample TestMethod3(string astrName);

    [OperationContract]
    string TestMethod4(object astrName);
}

[DataContract]
public class busSample 
{

    [DataMember]
    public string istrName { get; set; }

    public busSample()
    {

        this.istrName = "ABC";
    }
}

使用WCFTestClient测试服务时，出现类似“反序列化程序不知道要反序列化的类型的错误。请检查要序列化的类型是否与此处要反序列化的输入代码具有相同的约定。”

我认为您只需要将故障合同属性从类移到方法上即可。

   [ServiceContract]
//[FaultContract(typeof(object))]
[ServiceKnownType(typeof(busSample))]
public interface IUPSBusinessTier
{
    [FaultContract(typeof(object))]
    [OperationContract]
    string TestMethod1(string astrName);

    [FaultContract(typeof(object))]
    [OperationContract]
    void TestMethod2(busSample abusSample);
