WCF DataContract与DataContract接口

Question

WCF新手.

DataContact类可以从Interface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

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; }
}

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，以便它可以在另一端反序列化您发送的接口。
