在c＃中使用异步套接字发送对象 [英] sending object using asynchronous socket in c#

问题描述

我正在开发基于套接字的客户端/服务器应用程序。我想将我定义的类的对象发送到服务器。这是My Defined类

Hi,


I am working on a socket based client/server application. I want to send a object of my defined Class to server. Here is My Defined class

public class ClientData
{
    int clientId;
    string clientName;
    string message;
    public ClientData(int _id, string _name, string _message)
    {
        this.clientId = _id;
        this.clientName = _name;
        tbis.message = _message
    }
}

我使用异步套接字所以我是使用 Socket.BeginSend 函数。但我的问题是BeginSend只接受字节数组作为数据缓冲区，我不知道如何将ClientData对象转换为字节数组，而不是将其转换回服务器端的ClientData对象。



提前感谢您的时间。

I am using asyncronous sockets so i am using Socket.BeginSend function. But my problem is that BeginSend only takes array of bytes as data buffer, i dont know how to convert ClientData object to array of bytes and than convert it back to ClientData object on server side.

thanks in advance for you time.

推荐答案

使用序列化是一种好方法，但是它增加了很多你可能不需要的开销。我会添加两个函数，例如：

Using serialization is a good way, however it adds a lot of overhead that you probably don't need. I would add two functions, like:

public byte[] ToBytes()
{
  using (MemoryStream ms = new MemoryStream)
  {
    BinaryWriter bw = new BinaryWriter(ms);
    bw.Write(clientId);
    bw.Write(clientName);
    bw.Write(message);
  
    return ms.ToArray()
  }
}

public static ClientData FromBytes(byte[] buffer)
{
  ClientData retVal = new ClientData();

  using (MemoryStream ms = new MemoryStream(buffer))
  {
    BinaryReader br = new BinaryReader(ms);
    retVal.clientId = br.ReadInt32()
    retVal.clientName = br.ReadString();
    retVal.message = br.ReadString();
  }

  return retVal;
}

只需确保将字符串初始化为 string.empty 而不是null，以便它可以读取并正确写入它们。

Just make sure to initialize your strings to string.empty instead of null so that it can read them and write them correctly.
