[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; }
}

解决方法@H_301_10@

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; }
}

你不能这样做,可悲的是：

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; }
}
