将类对象转换为字节并从字节创建对象

这可能是你要找的

从您的评论和更新中收集的假设如下

• 您需要一种通用的方式来序列化类（消息）
• 您希望能够通过线路（套接字，而不是 wcf）使用它
• 它符合插座制度
• 您需要一些基本的防止腐败的保护
• 您希望它易于使用

注意：这里可能有很多可以改进的地方，但这只是给你一些想法

如果您使用类似 webservices 的东西，那么整个答案都是无效的，这实际上只是一种适用于套接字的 adhock 序列化方法

概述

Package 类具有一些用于以下的方法

• 能够将对象序列化为字节
• 能够将字节反序列化为对象
• 可以创建带有标头信息的包
• 标头包含您的消息类型（选项）
• 整个包装的长度
• 一些基本的检查求和和标记，如果发生损坏，您可以验证包

所以鉴于以下几点

消息枚举

// Some predefined messages
public enum MessageType : byte
{
   MyClass,
   MyOtherClass,
   Message3,
   Message4,
}

您想通过电汇发送的某些类

// a serilaizable class
// Make this as you like
[Serializable]
public class MyClass
{
   public byte[] SomeArbitaryBytes { get; set; }
   public string SomeArbitaryString { get; set; }
   public int SomeArbitaryInt { get; set; }
   public double SomeArbitaryDouble { get; set; }
   public MyClass()
   {
      SomeArbitaryString = "hello";
      SomeArbitaryInt = 7;
      SomeArbitaryDouble = 98.1;
      SomeArbitaryBytes = new byte[10];
      for (var i = 0; i < SomeArbitaryBytes.Length; i++)
      {
         SomeArbitaryBytes[i] = (byte)i;
      }
   }
}

包类

public static class Package
{
   // Method for basic checksum
   private static byte GetBasicChecksum(this byte[] data)
   {
      byte sum = 0;
      unchecked // Let overflow occur without exceptions
      {
         foreach (byte b in data)
         {
            sum += b;
         }
      }
      return sum;
   }
   // Serialize to bytes (BinaryFormatter)
   public static byte[] SerializeToBytes<T>(this T source)
   {
      using (var stream = new MemoryStream())
      {
         var formatter = new BinaryFormatter();
         formatter.Serialize(stream, source);
         return stream.ToArray();
      }
   }
   // Deerialize from bytes (BinaryFormatter)
   public static T DeserializeFromBytes<T>(this byte[] source)
   {
      using (var stream = new MemoryStream(source))
      {
         var formatter = new BinaryFormatter();
         stream.Seek(0, SeekOrigin.Begin);
         return (T)formatter.Deserialize(stream);
      }
   }
   // Check if we have enough data
   // will throw if it detects a corruption (basic)
   // return false if there isnt enough data to determine
   // return true and length of the package if sucessfull
   public static bool HasValidPackage(this Stream stream, out Int32 messageSize)
   {
      messageSize = -1;
      if (stream.Length - stream.Position < sizeof(byte) * 2 + sizeof(Int32))
         return false;

      var stx = stream.ReadByte();
      if (stx != 2)
         throw new InvalidDataException("Invalid Package : STX Failed");
      var packageLength = new byte[sizeof(Int32)];
      stream.Read(packageLength, 0, sizeof(Int32));
      messageSize = BitConverter.ToInt32(packageLength, 0) - sizeof(byte) * 3;
      var checkSum = stream.ReadByte();
      if (checkSum != packageLength.GetBasicChecksum())
         throw new InvalidDataException("Invalid Package : CheckSum Failed");
      return stream.Length >= messageSize;
   }
   // Pack the message
   public static byte[] PackMessage<T>(this T source, MessageType messageType)
   {
      var buffer = source.SerializeToBytes();
      var packageLength = BitConverter.GetBytes(buffer.Length + sizeof(byte) * 3);
      using (var stream = new MemoryStream())
      {
         stream.WriteByte(2);
         stream.Write(packageLength, 0, sizeof(Int32));
         stream.WriteByte(packageLength.GetBasicChecksum());
         stream.WriteByte((byte)messageType);
         stream.Write(buffer, 0, buffer.Length);
         stream.WriteByte(3);
         return stream.ToArray();
      }
   }
   // Unpack the message
   public static MessageType UnPackMessage(this Stream stream, Int32 messageSize, out byte[] buffer)
   {
      var messageType = (MessageType)stream.ReadByte();
      buffer = new byte[messageSize];
      stream.Read(buffer, 0, buffer.Length);
      var etx = stream.ReadByte();
      if (etx != 3)
         throw new InvalidDataException("Invalid Package : ETX Failed");
      return messageType;
   }
}

客户端代码

// create your class 
var myClass = new MyClass();
// Create a package out of it
var bytes = myClass.PackMessage(MessageType.MyClass);

服务器端代码

// this is server side
using (var stream = new MemoryStream(bytes))
{
   Int32 messageSize;
   // if we have a valid package do stuff
   // this loops until there isnt enough data for a package or empty
   while (stream.HasValidPackage(out messageSize))
   {
      byte[] buffer;
      switch (stream.UnPackMessage(messageSize, out buffer))
      {
         case MessageType.MyClass:
            var myClassCopy = buffer.DeserializeFromBytes<MyClass>();
            // do stuff with your class
            break;
         case MessageType.MyOtherClass:
            break;
         case MessageType.Message3:
            break;
         case MessageType.Message4:
            break;
         default:
            throw new ArgumentOutOfRangeException();
      }
   }
   // do something with the remaining bytes here, if any, i.e partial package
}

C# 不是 C/C++，所以你不能随心所欲地使用地址算术（据我所知）。

在.NET中，与字节数组相互转换的正确方法是序列化/反序列化。

模拟低级，也许你需要 BitConverter。

很难判断序列化是最终结果，还是只是用于尝试实现其他目标的方法。 步入其他目标。 但是，字节数组序列化得很好：

[Serializable]
public class ByteArrayClass
{
    public byte[] FirstArray {get; set;}
    public byte[] SecondArray {get; set;}           
}

然后做一个往返测试：

    ByteArrayClass myFoo = new ByteArrayClass();
    myFoo.FirstArray = new byte[] { 3, 10, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
    myFoo.SecondArray = new byte[] { 3, 11, 5, 1, 21, 23, 4, 5, 4, 7, 8, 9, 10 };
    using (FileStream fs = new FileStream(@"C:'Temp'Arry.Bin", 
                          FileMode.Create, FileAccess.Write))
    {
        BinaryFormatter bf = new BinaryFormatter();
        bf.Serialize(fs, myFoo);
    }
    ByteArrayInClass newFoo;
    using (FileStream fs = new FileStream(@"C:'Temp'Arry.Bin", 
                        FileMode.Open, FileAccess.Read))
    {
        BinaryFormatter bf = new BinaryFormatter();
        newFoo = (ByteArrayClass) bf.Deserialize(fs);
    }

如果我不补充ProtoBuf-Net是一个比BinaryFormatter更快，更好的序列化器，那将是我的失职。 它也更适合数据传输 - 由一个程序集序列化的类可以由另一个程序集反序列化，并且它产生的输出较小。

很难说你真正想要实现什么，但我会试一试。

这是否符合您的预期目标？

public class ByteArrayInClass
{
   public byte Option { get; set; }
   public ushort Elements { get; set; }
   public byte[] Bytes { get; set; }
   public ByteArrayInClass(byte option, ushort nElements)
   {
      this.Option = option;
      this.Elements = nElements;
      this.Bytes = new byte[nElements];
      for (var i = 0; i < nElements; i++)
      {
         this.Bytes[i] = (byte)i;
      }
   }
   public ByteArrayInClass(byte[] array)
   {
      this.Elements = (ushort)array.Length;
      this.Bytes = new byte[this.Elements];
      array.CopyTo(this.Bytes, 0);
   }
   public static byte[] ObjectToBytes(ByteArrayInClass value)
   {
      var result = new byte[value.Elements];
      value.Bytes.CopyTo(result, 0);
      return result;
   }
   public static ByteArrayInClass BytesToObject(byte[] bytes)
   {
      return new ByteArrayInClass(bytes);
   }
}
