byte[] 转换成string 时数据丢失的问题
using System;
using System.Collections.Generic;
using System.Text;
using System.Xml.Serialization;

namespace Operate
{
  [Serializable]
  public class Entity
  {
  public Entity()
  {
  }
  private string mid;
  private string annex;
  private string filename;

  public string Mid
  {
  get
  {
  return mid;
  }
  set
  {
  mid = value;
  }
  }
   
  public string FileName
  {
  get
  {
  return filename;
  }
  set
  {
  filename = value;
  }
  }


  public string Annex
  {
  get
  {
  return annex;
  }
  set
  {
  annex = value;
  }
  }
  }
}

上面是一个实体类



foreach (Entity obj in arrayEntity)
 {
  string strentity = obj.Mid + ";" + obj.FileName + ";" + obj.Annex;//将实体类转换成字符串用socket发送到服务器
   
  if(this.RecvMessage().StartsWith("ok"))
  {
   
  this.SendMessage(strentity); //发送到服务器的方法
 
  if (this.RecvMessage().StartsWith("InertAnnexSucessful"))
  {
  txtState.Text = "服务器成功执行附件: " + obj.FileName + "\r\n" + txtState.Text;
  executeAnnex = true;
  }
  }
}

上面循环发送实体类的字符串





  public string recvMessage()
{
  byte[] recvBytes = new byte[Int32.Parse(ss)];
  int bytes=0;
  bytes += s.Receive(recvBytes, recvBytes.Length, 0);
  byte[] gb = Encoding.Convert(utf8, gb2312, recvBytes);
  string sGb = gb2312.GetString(gb);
}


上面这个是接收消息的方法



public string sendMessage(string mes)
{
byte[] bgb = gb2312.GetBytes(mes);
  byte[] butf = Encoding.Convert(gb2312, utf8, bgb);
  client.Send(butf);
}

上面这个是发送到服务器的方法







  while (true)
  {
  string ss = this.RecvMessage();
  if (ss.StartsWith("Close"))
  {
  CloseSocketList.Add(s);
  break;
  }
  else
  {
  this.SendMessage("ok");
  byte[] recvBytes = new byte[Int32.Parse(ss)];
  int bytes=0;
  bytes += s.Receive(recvBytes, recvBytes.Length, 0);//这里可以完全接收到数据
  byte[] gb = Encoding.Convert(utf8, gb2312, recvBytes);这个转换就丢失了一些数据了，不知道怎么解决
  string sGb = gb2312.GetString(gb);
  string[] vv = sGb.Split(';');
  int i = 0;
  foreach (string ssss in vv)
  {
  if (i == 0)
  {
  entity.Mid = ssss;
  }
  if (i == 1)
