protobuf repeated的用法

//User.proto
package ProtoMessage;

message User
{
    required uint32 ID = 1;
    required string name = 2;
}

message UserList
{
    repeated User user = 1;
}

message RoomList
{
    repeated string name = 1;
}

编译成User.pb.h和User.pb.cpp文件

cd protoc.exe所在的目录

protoc -I=. –cpp_out=. User.proto

配置VS2013环境变量

1、头文件目录

2、库目录

3、库文件名

测试：

// Messages.cpp : 定义控制台应用程序的入口点。
//

#include "stdafx.h"
#include <iostream>
#include "messages.pb.h"
#include "User.pb.h"
//using namespace messagesuites;
