protobuf repeated 类型与C++的Vector，list类似，这里可以理解为指定类型的数组。

首先定义一个protobuf结构，如下：

//进入房间(广播)
message Actor_GamerEnterRoom_Ntt // IActorMessage
{
	int32 RpcId = 90;
	int64 ActorId = 93;
    repeated GamerInfo Gamers = 1;
}

下面我们以例子简单说明如何使用：

public partial class Actor_GamerEnterRoom_Ntt : pb::IMessage {
    private static readonly pb::MessageParser<Actor_GamerEnterRoom_Ntt> _parser = new pb::MessageParser<Actor_GamerEnterRoom_Ntt>(() => (Actor_GamerEnterRoom_Ntt)MessagePool.Instance.Fetch(typeof(Actor_GamerEnterRoom_Ntt)));
    public static pb::MessageParser<Actor_GamerEnterRoom_Ntt> Parser { get { return _parser; } }

    private int rpcId_;
    public int RpcId {
      get { return rpcId_; }
      set {
        rpcId_ = value;
      }
    }

    private long actorId_;
    public long ActorId {
      get { return actorId_; }
      set {
        actorId_ = value;
      }
    }

    private static readonly pb::FieldCodec<global::ETModel.GamerInfo> _repeated_gamers_codec
        = pb::FieldCodec.ForMessage(10, global::ETModel.GamerInfo.Parser);
    private pbc::RepeatedField<global::ETModel.GamerInfo> gamers_ = new pbc::RepeatedField<global::ETModel.GamerInfo>();
    public pbc::RepeatedField<global::ETModel.GamerInfo> Gamers {
      get { return gamers_; }
      set { gamers_ = value; }
    }

    public void WriteTo(pb::CodedOutputStream output) {
      gamers_.WriteTo(output, _repeated_gamers_codec);
      if (RpcId != 0) {
        output.WriteRawTag(208, 5);
        output.WriteInt32(RpcId);
      }
      if (ActorId != 0L) {
        output.WriteRawTag(232, 5);
        output.WriteInt64(ActorId);
      }
    }

    public int CalculateSize() {
      int size = 0;
      if (RpcId != 0) {
        size += 2 + pb::CodedOutputStream.ComputeInt32Size(RpcId);
      }
      if (ActorId != 0L) {
        size += 2 + pb::CodedOutputStream.ComputeInt64Size(ActorId);
      }
      size += gamers_.CalculateSize(_repeated_gamers_codec);
      return size;
    }

    public void MergeFrom(pb::CodedInputStream input) {
      for (int i = 0; i < gamers_.Count; i++) { MessagePool.Instance.Recycle(gamers_[i]); }
      gamers_.Clear();
      rpcId_ = 0;
      actorId_ = 0;
      uint tag;
      while ((tag = input.ReadTag()) != 0) {
        switch(tag) {
          default:
            input.SkipLastField();
            break;
          case 10: {
            gamers_.AddEntriesFrom(input, _repeated_gamers_codec);
            break;
          }
          case 720: {
            RpcId = input.ReadInt32();
            break;
          }
          case 744: {
            ActorId = input.ReadInt64();
            break;
          }
        }
      }
    }

  }
