Protobuf.NET 使用 [英] Protobuf.NET using

问题描述

需要在托管 C# 和非托管 C++ 之间发送一些数据.经过一番研究我尝试使用 Protobuf.NET.

我不确定我是否了解 ProtoBuf 的功能...

1. 在 Proto 中构建类型定义.我在 c++ 和 c# 项目中都需要这个类型定义
2. 使用命令行工具protogen.exe"从类型定义中获取 .cs 文件和 .cpp、.h
3. 将 .cs 文件复制到我的 c# 项目中，并将 .cpp、.h 复制到我的 c++ 解决方案中.

解决这个问题似乎很愚蠢.这是我的问题和问题.

1. 是否可以在 c# 中定义类型以生成 c++ 中的文件?
2. 尝试将命令行工具 protogen.exe 与以下文件一起使用

<小时>

test1.proto

<块引用>

使用ProtoBuf；命名空间协议缓冲区{[原合同]班级人物{[ProtoMember(1)]公共整数 ID {get;set;}[ProtoMember(2)]公共字符串名称{获取；放;}}}

<小时>

test2.proto

message Person {所需的 int32 id = 1；所需的字符串名称 = 2;可选字符串 email = 3;}

<小时>

没有什么对我有用.真的什么都试过了.我把 proto 文件放入命令行目录，尝试了每个选项来设置目录.如何轻松构建它们?第二个文件正在使用用于 c++ 的标准 proto 命令行工具，但我也需要它用于 c#.真的需要你的帮助.

解决方案

首先，请注意 protobuf-net 只是 .NET 的一个可用实现；无论如何...

"test1.proto" 不是 .proto - 它是 C#；与 protobuf-net 一起使用 不需要 .proto，但在您的互操作场景中，这是一个非常好的主意.有 VS2010 插件，或者 protobuf-net zip 中的 protogen 工具:

 protogen -i:test2.proto -o:test2.cs

这应该生成带有内容的 test2.cs:

//----------------------------------------------------------------//<自动生成>//此代码是由工具生成的.////对此文件的更改可能会导致不正确的行为，如果//重新生成代码.//</自动生成>//------------------------------------------------------------------------------//生成自:test2.proto命名空间 test2{[global::System.Serializable, global::ProtoBuf.ProtoContract(Name=@"Person")]公共部分类 Person : global::ProtoBuf.IExtensible{公共人(){}私有整数_id；[global::ProtoBuf.ProtoMember(1, IsRequired = true, Name=@"id", DataFormat = global::ProtoBuf.DataFormat.TwosComplement)]公共整数 ID{得到{返回_id;}设置 { _id = 值；}}私人字符串_name;[global::ProtoBuf.ProtoMember(2, IsRequired = true, Name=@"name", DataFormat = global::ProtoBuf.DataFormat.Default)]公共字符串名称{得到 { 返回 _name;}设置 { _name = 值；}}私人字符串 _email = "";[global::ProtoBuf.ProtoMember(3, IsRequired = false, Name=@"email", DataFormat = global::ProtoBuf.DataFormat.Default)][全局::System.ComponentModel.DefaultValue("")]公共字符串电子邮件{得到 { 返回 _email;}设置 { _email = 值；}}私有全局::ProtoBuf.IExtension extensionObject;global::ProtoBuf.IExtension global::ProtoBuf.IExtensible.GetExtensionObject(bool createIfMissing){ return global::ProtoBuf.Extensible.GetExtensionObject(ref extensionObject, createIfMissing);}}}

请注意，如果您愿意，还有其他开关，例如，尝试区分大小写(因此您将获得 Id、Name、Email> 等)，或者希望它包含额外的序列化器支持(BinaryFormatter、DataContractSerializer 等)

Need to send some data between managed c# and unmanaged c++. After some research I tried to use Protobuf.NET.

I'm not sure if I understand functionality of ProtoBuf...

1. Build a type definition in Proto. I need this type definition in both projects c++ and c#
2. Use the command-line tool "protogen.exe" to get an .cs file and .cpp, .h from the type definition
3. Copy the .cs files into my c# project and the .cpp, .h in my c++ solution.

Seems I'm to stupid to to solve this. Here are my problem and questions.

1. Is it possible to define the type in c# to generate the files in for c++ ?
2. Tried to use the command-line tool protogen.exe with the following files

---

test1.proto

using ProtoBuf;
namespace ProtocolBuffers
{
    [ProtoContract]
    class Person
    {
        [ProtoMember(1)]
        public int Id {get;set;}
        [ProtoMember(2)]
        public string Name { get; set; }
    }
}

---

test2.proto

message Person {
  required int32 id = 1;
  required string name = 2;
  optional string email = 3;
}

---

Nothing is working for me. Really tried everything. I put the proto files into the commandline dir, tried every option to set the dir. How to build them easily ? The second file is working with standard proto commandline tool for c++ but i need it for c# too. Really need your help.

解决方案

Firstly, note that protobuf-net is just one available implementation for .NET; anyway...

"test1.proto" is not a .proto - it is C#; a .proto is not required for use with protobuf-net, but in your interop scenario it is a very good idea. There is VS2010 plugin for this, or alternatively the protogen tool that is in the protobuf-net zip:

 protogen -i:test2.proto -o:test2.cs

This should generate test2.cs with the contents:

//------------------------------------------------------------------------------
// <auto-generated>
//     This code was generated by a tool.
//
//     Changes to this file may cause incorrect behavior and will be lost if
//     the code is regenerated.
// </auto-generated>
//------------------------------------------------------------------------------

// Generated from: test2.proto
namespace test2
{
  [global::System.Serializable, global::ProtoBuf.ProtoContract(Name=@"Person")]
  public partial class Person : global::ProtoBuf.IExtensible
  {
    public Person() {}

    private int _id;
    [global::ProtoBuf.ProtoMember(1, IsRequired = true, Name=@"id", DataFormat = global::ProtoBuf.DataFormat.TwosComplement)]
    public int id
    {
      get { return _id; }
      set { _id = value; }
    }
    private string _name;
    [global::ProtoBuf.ProtoMember(2, IsRequired = true, Name=@"name", DataFormat = global::ProtoBuf.DataFormat.Default)]
    public string name
    {
      get { return _name; }
      set { _name = value; }
    }

    private string _email = "";
    [global::ProtoBuf.ProtoMember(3, IsRequired = false, Name=@"email", DataFormat = global::ProtoBuf.DataFormat.Default)]
    [global::System.ComponentModel.DefaultValue("")]
    public string email
    {
      get { return _email; }
      set { _email = value; }
    }
    private global::ProtoBuf.IExtension extensionObject;
    global::ProtoBuf.IExtension global::ProtoBuf.IExtensible.GetExtensionObject(bool createIfMissing)
      { return global::ProtoBuf.Extensible.GetExtensionObject(ref extensionObject, createIfMissing); }
  }

}

Note that there are additional switches if you want, for example, it to attempt case normalization (so you get Id, Name, Email, etc), or want it to include additional serializer support (BinaryFormatter, DataContractSerializer, etc)
