Protobuf 学习简记（三）Unity C#中的序列化与反序列化

对文本的序列化与反序列化

private void Text()
{
    
    
    TestMsg1 myTestMsg = new TestMsg1();
    myTestMsg.TestInt32 = 1;
    myTestMsg.ArrString.Add("wy");
    myTestMsg.ArrString.Add("pnb");
    myTestMsg.ArrString.Add("lzq");
    myTestMsg.Map1.Add(1, "ywj");
    myTestMsg.Map1.Add(2, "zzs");
	//序列化
    string path = Application.persistentDataPath + "/testMsg.msg";
    using (FileStream fs = new FileStream(path, FileMode.OpenOrCreate))
    {
    
    
        myTestMsg.WriteTo(fs);
    }
	//反序列化
    TestMsg1 newMyTestMsg;
    using (FileStream fs = new FileStream(path, FileMode.Open))
    {
    
    
        newMyTestMsg = TestMsg1.Parser.ParseFrom(fs);
    }
    Debug.Log(newMyTestMsg.TestInt32);
    Debug.Log(newMyTestMsg.ArrString);
    Debug.Log(newMyTestMsg.ArrString.Count);
    Debug.Log(newMyTestMsg.Map1[1]);
    Debug.Log(newMyTestMsg.Map1[2]);
}

内存二进制流的序列化与反序列化

方法一

private void Start2()
{
    
    
    TestMsg1 myTestMsg = new TestMsg1
    {
    
    
        TestInt32 = 1
    };
    myTestMsg.ArrString.Add("wy");
    myTestMsg.ArrString.Add("pnb");
    myTestMsg.ArrString.Add("lzq");
    myTestMsg.Map1.Add(1, "ywj");
    myTestMsg.Map1.Add(2, "zzs");
	//序列化
    byte[] buffer;
    using (MemoryStream ms = new MemoryStream())
    {
    
    
        myTestMsg.WriteTo(ms);
        buffer = ms.ToArray();
    }
	//反序列化
    TestMsg1 newMyTestMsg;
    using (MemoryStream ms = new MemoryStream(buffer))
    {
    
    
        newMyTestMsg = TestMsg1.Parser.ParseFrom(ms);
    }
    Debug.Log(newMyTestMsg.TestInt32);
    Debug.Log(newMyTestMsg.ArrString);
    Debug.Log(newMyTestMsg.ArrString.Count);
    Debug.Log(newMyTestMsg.Map1[1]);
    Debug.Log(newMyTestMsg.Map1[2]);
}

方法二

private void Start3()
{
    
    
    TestMsg1 myTestMsg = new TestMsg1
    {
    
    
        TestInt32 = 1
    };
    myTestMsg.ArrString.Add("wy");
    myTestMsg.ArrString.Add("pnb");
    myTestMsg.ArrString.Add("lzq");
    myTestMsg.Map1.Add(1, "ywj");
    myTestMsg.Map1.Add(2, "zzs");

    byte[] buffer = myTestMsg.ToByteArray();//序列化
    TestMsg1 newMyTestMsg = TestMsg1.Parser.ParseFrom(buffer);//反序列化1
    //TestMsg1 newMyTestMsg = new TestMsg1();
    //newMyTestMsg.MergeFrom(buffer);//反序列化2

    Debug.Log(newMyTestMsg.TestInt32);
    Debug.Log(newMyTestMsg.ArrString);
    Debug.Log(newMyTestMsg.ArrString.Count);
    Debug.Log(newMyTestMsg.Map1[1]);
    Debug.Log(newMyTestMsg.Map1[2]);
}

反序列化1与反序列化2都可以正常使用。
