与protobuf-net和C＃的接口 [英] Interfaces with protobuf-net and C#

问题描述

有人知道为接口设置 ProtoContract 的正确方法是什么吗？

Does anybody know what is the right way to set up a ProtoContract for an Interface?

I得到仅使用属性的以下异常 一旦生成序列化器，类型就无法更改。

I get the following exception "The type cannot be changed once a serializer has been generated" using only attributes.

使用的代码：

    [ProtoContract]
    public class Lesson5TestClass2 : ILesson5TestInteface1
    {
        [ProtoMember(1)]
        public string Name { get; set; }
        [ProtoMember(2)]
        public string Phone { get; set; }
    }

    [ProtoContract]
    [ProtoInclude(1000, typeof(Lesson5TestClass2))]
    public interface ILesson5TestInteface1
    {
        [ProtoMember(1)]
        string Name { get; set; }
        [ProtoMember(2)]
        string Phone { get; set; }
    }

只有添加以下设置，我才能反序列化： / p>

I'm able to deserialize only if I add the following setting:

  RuntimeTypeModel.Default.Add(typeof (ILesson5TestInteface1), true)
      .AddSubType(50, typeof(Lesson5TestClass2));

我真的很想仅使用属性来配置它。

I'd really love to configure this using only attributes.

我正在使用NuGet的protobuf-net r470。

I'm using protobuf-net r470 from NuGet.

BTW：此示例来自一组通过测试的教训，显示了操作方法为我的同事使用protobuf-net进行序列化。

推荐答案

有趣；是的，看起来好像有东西在上面。但是，当作为成员公开时，它确实起作用，即

Interesting; yes, it looks like something is up there. However, it does work when exposed as a member, i.e.

[ProtoContract]
class Wrapper
{
    [ProtoMember(1)]
    public ILesson5TestInteface1 Content { get; set; }
}
static class Program
{
    static void Main()
    {
        Wrapper obj = new Wrapper
        {
            Content = new Lesson5TestClass2()
        }, clone;
        using(var ms = new MemoryStream())
        {
            Serializer.Serialize(ms, obj);
            ms.Position = 0;
            clone = Serializer.Deserialize<Wrapper>(ms);
        }
        // here clone.Content *is* a Lesson5TestClass2 instance
    }
}

我将不得不看一下接口支持如何作为 root 对象。

I will have to look to see what is up with interface support as the root object.
