socket数据包及解码

建立数据包：

static Char start = (Char)0x0a;//开始标记
static Char end = (Char)0x1a;//结束符
static Char jG = (Char)0x09; 

private Byte[] BuildContent()      

   {

         int result = 1;          

        if (this._successful)       

               result = 0;

        string content = this._index + jG + result + jG + this._msg;   

        return Encoding.ASCII.GetBytes(content);   

  }

public Byte[] ToByte()
        {
            int len = 0;
            Byte startByte = Convert.ToByte(start);
            len += 1;
            len += 4;
            Byte[] content = this.BuildContent();
            len += content.Length;
            Byte endByre = Convert.ToByte(end);
            len += 1;
            Char[] lengthChar = len.ToString().PadLeft(4, ' ').ToCharArray();
            Byte[] lengthByte = new Byte[lengthChar.Length];
            for (var i = 0; i < lengthChar.Length; i++)
            {
                lengthByte[i] = Convert.ToByte(lengthChar[i]);
            }
            Byte[] bs = new Byte[len];
            bs[0] = startByte;
            Array.Copy(lengthByte, 0, bs, 1, lengthByte.Length);
            Array.Copy(content, 0, bs, 5, content.Length);
            bs[len - 1] = endByre;
            return bs;
        }

解码：

public string[] Parse()     

    {            

        if (this._rd == null) return null;

        string data = Encoding.ASCII.GetString(this._rd.Data,this._rd.Offset,this._rd.Length);      

        string temp = data.Split(start)[1].Split(end)[0].Trim();     

        string dataLength = this._rd.Length.ToString();     

        string strContent = temp.Substring(dataLength.Length, temp.Length - dataLength.Length);    

         string[] content = strContent.Split(jG);   

          return content;    

     }
