WCF DataContract与DataContract接口的区别

Question

我是新手，对WCF不太熟悉。

可以让DataContact类继承接口吗？

例如：

[DataContract(Namespace = ...........)]
public class VesselSequence : IVesselSequence
{

    [DataMember]
    public int AllocationId { get; set; }

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

interface VesselSequence : IVesselSequence
{
    public int AllocationId { get; set; }
    public string ScenarioName { get; set; }
}

你可以这样做：

[DataContract(Namespace = ...........)]
public class VesselSequence : IVesselSequence
{
    [DataMember]
    public int AllocationId { get; set; }
    [DataMember]
    public string ScenarioName { get; set; }
}

interface IVesselSequence
{
    int AllocationId { get; set; }
    string ScenarioName { get; set; }
}

很遗憾，您不能这样做：

public class VesselSequence : IVesselSequence
{
    public int AllocationId { get; set; }
    public string ScenarioName { get; set; }
}

[DataContract(Namespace = ...........)]
interface IVesselSequence
{
    [DataMember]
    int AllocationId { get; set; }
    [DataMember]
    string ScenarioName { get; set; }
}

当然可以，但请记住，如果您返回接口类型，则必须为反序列化引擎定义KnownTypes属性，以便它可以在另一端反序列化您发送的接口。
