.net8 C# 封包与解包 BinaryFormatter 类已标记为过时
本帖最后由 shiy720 于 2024-6-19 11:25 编辑在 .NET 8 中，BinaryFormatter 类已标记为过时，不再建议使用。相反，您可以使用BinaryWriter 和 BinaryReader 类来打包和解压缩数据。下面是在 .NET 8 中打包和解压缩数据的更新示例:using System;
using System.IO;
public class Packet
{
public int Id { get; set; }
public string Message { get; set; }
}
class Program
{
static void Main(string[] args)
{
Packet packet = new Packet { Id = 1, Message = "Hello, World!" };
using (MemoryStream stream = new MemoryStream())
{
using (BinaryWriter writer = new BinaryWriter(stream))
{
writer.Write(packet.Id);
writer.Write(packet.Message);
byte[] packedData = stream.ToArray();
// Send packed data over the network
Console.WriteLine("Packed data: ");
foreach (byte b in packedData)
{
Console.Write($"{b:X2} ");
}
Console.WriteLine();
}
}
}
}如果要解包 你可以使用 BinaryReader 类来处理
class Program
{
static void Main(string[] args)
{
byte[] packedData = new byte[] { 0x01, 0x00, 0x00, 0x00, 0x05, 0x48, 0x65, 0x6c, 0x6c, 0x6f, 0x2c, 0x20, 0x57, 0x6f, 0x72, 0x6c, 0x64, 0x21 };
using (MemoryStream stream = new MemoryStream(packedData))
{
using (BinaryReader reader = new BinaryReader(stream))
{
int id = reader.ReadInt32();
string message = reader.ReadString();
Packet packet = new Packet { Id = id, Message = message };
Console.WriteLine($"Unpacked data: Id={packet.Id}, Message={packet.Message}");
}
}
}
}
