带有Object类型参数的WCF OperationContract

Question

我使用服务和数据合同在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";
    }
}

在使用WCFTestClient测试服务时，收到类似这样的错误：“反序列化程序不知道要反序列化哪个类型。请检查正在序列化的类型是否与正在反序列化的enter code here类型具有相同的约定。”

我认为您只需要将错误协定属性从类移动到方法上。

   [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);
