接第01部分，本节用来说明C#语言的代码实现。

使用Protoc.exe生成cs代码之后，会生成两个cs文件，Client与Server都需要包含这两个文件。

首先是Server端：
1、新建一个Console项目，引用Protoc程序集中以下几个dll文件，并添加生成的CS文件
Google.Protobuf.dll
Grpc.Core.dll
System.Interactive.Async.dll

2、新建一个类MyGRPCServer，实现JustATest.IJustATest接口

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Com.Neohope.Protobuf.Grpc.Test;
using Grpc.Core;

namespace TestProtoBufferCliet
{
    class MyGRPCServer : JustATest.IJustATest
    {
        public Task<AddResponse> Add(AddRequest request, ServerCallContext context)
        {
            AddResponse rsp  = new AddResponse();
            rsp.C = request.A + request.B;
            return Task.FromResult(rsp);
        }

        public Task<HelloResponse> SayHelloTo(Person request, ServerCallContext context)
        {
            HelloResponse rsp = new HelloResponse();
            rsp.Rsp = "Hello " + request.Name;
            return Task.FromResult(rsp);
        }
    }
}

3、修改Program.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Com.Neohope.Protobuf.Grpc.Test;
using Grpc.Core;
using TestProtoBufferCliet;


namespace TestProtoBuffer
{
    class Program
    {
        static void Main(string[] args)
        {
            Server server = new Server
            {
                Services = { JustATest.BindService(new MyGRPCServer()) },
                Ports = { new ServerPort("localhost", 1900, ServerCredentials.Insecure) }
            };
            server.Start();

            
        }
    }
}

4、编译运行
其中，非托管dll要如下放置

.
│  yourprogram.exe
│  
└─nativelibs
    ├─windows_x64
    │      grpc_csharp_ext.dll
    │      
    └─windows_x86
            grpc_csharp_ext.dll
            

然后是Client端：
1、新建一个Console项目，引用Protoc程序集中以下几个dll文件，并添加生成的CS文件
Google.Protobuf.dll
Grpc.Core.dll
System.Interactive.Async.dll

2、修改Program.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Com.Neohope.Protobuf.Grpc.Test;
using Grpc.Core;

namespace TestProtoBufferCliet
{
    class Program
    {
        static void Main(string[] args)
        {
            Channel channel = new Channel("127.0.0.1:1900", ChannelCredentials.Insecure);
            JustATest.JustATestClient client = JustATest.NewClient(channel);

            Person p = new Person();
            p.Name = "neohope";
            p.Age = 30;
            p.Sex = Person.Types.SexType.MALE;
            HelloResponse prsp = client.SayHelloTo(p);
            Console.WriteLine(prsp.Rsp);

            AddRequest areq = new AddRequest();
            areq.A = 1;
            areq.B = 2;
            AddResponse arsp = client.Add(areq);
            Console.WriteLine(arsp.C);

            channel.ShutdownAsync().Wait();
            Console.ReadLine();
        }
    }
}

3、编译运行

    ├─windows_x64
    │      grpc_csharp_ext.dll

            grpc_csharp_ext.dll
