我单位客户端的序列化object结果和c#控制台服务器的结果不一样

Question

same class for serialize:

using System;
[Serializable]
class Class2
{
    public int a;
}

same serialize function:

        public static byte[] Serialize(object obj)
        {
            if (obj == null || !obj.GetType().IsSerializable)
            {
                return null;
            }

            BinaryFormatter formatter = new BinaryFormatter();
            using (MemoryStream stream = new MemoryStream())
            {
                formatter.Serialize(stream, obj);
                byte[] data = stream.ToArray();
                return data;
            }
        }

sever:

Class2 c = new Class2();
c.a = 1 ;
byte[] data = NetworkUtils.Serialize(c);
Console.WriteLine( BitConverter.ToString(data));

unity client:

Class2 c = new Class2();
c.a = 1;
byte[] data = NetworkUtils.Serialize(c);
Debug.Log("测试序列化 " + BitConverter.ToString(data));

is this problem about .net edition? unity is standard2,server is core3.1

unity result: 00-01-00-00-00-FF-FF-FF-FF-01-00-00-00-00-00-00-00-0C-02-00-00-00-46-41-73-73-65-6D-62-6C-79-2D-43-53-68-61-72-70-2C-20-56-65-72-73-69-6F-6E-3D-30-2E-30-2E-30-2E-30-2C-20-43-75-6C-74-75-72-65-3D-6E-65-75-74-72-61-6C-2C-20-50-75-62-6C-69-63-4B-65-79-54-6F-6B-65-6E-3D-6E-75-6C-6C-05-01-00-00-00-06-43-6C-61-73-73-32-01-00-00-00-01-61-00-08-02-00-00-00-01-00-00-00-0B UnityEngine.Debug:Log (object)

PS:If I make the class into a DLL file and import it, this problem will not appear,But this method is too troublesome

Answer 1

If you compare the strings what you get is on your server

FAssembly-CSharp, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null Class2 a

And in Unity

Game, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null Class2 a

(I left out the not printable Chars) The difference is the Assembly name. In Unity it is Game , on your server it is FAssembly .

In general as said STOP using BinaryFormatter at all! !

Despite the security concerns it is also a huge waste of bandwidth!

In Unity you send 111 and on the server even 122 bytes!

Your class has a single int field which only requires 4 bytes of data!

As said I would rather implement

[Serializable]
class Class2
{
    public int a;

    public byte[] ToBytes()
    {
        return BitConverter.GetBytes(a);
    }

    public Class2(){}

    public Class2(byte[] bytes)
    {
        a = BitConverter.ToInt32(bytes);
    }
}
