1. 通過Nuget下載Google.ProtocolBuffers，在目錄中找到net35下的文件，放入unity3d中作為插件

2.  1 PersonMessage.Builder personBuilder = PersonMessage.CreateBuilder();
    2         personBuilder.Id = 123;
    3         personBuilder.Age = 33;
    4         personBuilder.Sex = PersonMessage.Types.Sex.Male;
    5         personBuilder.Name = "
    
   protobuf";
    6         personBuilder.Phone = "1333333333";
    7         var person = personBuilder.Build();
    8         // 序列化到文件
    9         using (var stream = File.Create("person.bin"))
   10         {
   11             CodedOutputStream cos = CodedOutputStream.CreateInstance(stream);
   12             person.WriteTo(cos);
    
   13             cos.Flush();
   14         }
   15 
   16         // 從文件反序列化到對象
   17         using (var stream = File.OpenRead("person.bin"))
   18         {
   19             CodedInputStream cis = CodedInputStream.CreateInstance(stream);
   20             PersonMessage pm = PersonMessage.ParseFrom(cis);
   21             Debug.Log("
    
   從person.bin反序列化到對象:");
   22             Debug.LogFormat("person‘s name:{0}, person‘s age:{1}, person‘s phone:{2}", pm.Name, pm.Age, pm.Phone);
   23         }

   查看生成的person.bin

3. 執行後unity3d打印的輸出

在Unity3d中使用Google.ProtocolBuffers
