你能在WCF中使用接口作为DataMembers吗？

[DataContract]
public interface IMyData
{
    [DataMember]
    string Name { get; set; }

    [DataMember]
    int Age { get; set; }
}

public class MyData : IMyData
{
    public string Name { get; set; }
    public int Age { get; set; }
}

[ServiceContract]
public interface IMyService
{
    [OperationContract]
    IMyData GetData(string name);
}

public class MyService : IMyService
{
    public IMyData GetData(string name)
    {
        MyData data = new MyData { Name = name, Age = 25 };
        return data;
    }
}

using System.ServiceModel;

//...

ServiceHost host = new ServiceHost(typeof(MyService));
host.Open();
