WCF DataContract vs DataContract接口

Question

WCF新手。

DataContact类可以从接口继承吗？

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; }
}

Answer 1

您可以这样做：

[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; }
}

遗憾的是，你不能这样做：

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，如果您要返回接口类型，则必须为反序列化引擎定义KnownTypes属性，这样它就可以在另一端反序列化您发送的接口。
