c#从加密码狗读出来的十六进制串，怎么转换成字符串

[netxie]

原串：

以已之心，斗其之智AaBbCcXxZz

十六进制串：

D2D4D2D1D6AED0C4A3ACB6B7C6E4D6AED6C741614262436358785A7A

[hhhh63]

string strhex = "D2D4D2D1D6AED0C4A3ACB6B7C6E4D6AED6C741614262436358785A7A";
int n = strhex.Length / 2;
byte[] buf = new byte[n];
for( int i = 0; i < n; i++ )
buf[i] = byte.Parse( strhex.Substring( i*2, 2 ), System.Globalization.NumberStyles.HexNumber );

Encoding enc = Encoding.GetEncoding("GB2312");
string str = enc.GetString( buf );
Console.Write( str );

我做加密狗的时候，读出来的直接就是字节数组，那就更简单了。
byte[] buf = new byte[]{ 0xD6, 0xC7, 0x41 }; //加密狗二进制数据
Encoding enc = Encoding.GetEncoding("GB2312");
string str = enc.GetString( buf );
Console.Write( str );

以上 .net2003测试通过。

你指的是显示未加密前的串么，这个没有解密算法行么

12楼的看起来不错，楼主试试

[春天的气息]

怎么加的就怎么解呀，

[Quote=引用 12 楼 hhhh63 的回复:]
string strhex = "D2D4D2D1D6AED0C4A3ACB6B7C6E4D6AED6C741614262436358785A7A";
int n = strhex.Length / 2;

Encoding enc = Encoding.GetEncoding("GB2312");
string str = enc.GetString( buf );
Console.Write( str );

我做加密狗的时候，读…

这个可以

不知道加密算法啊！

11楼的写反了,通过byte转string的如下,很简单

        static void Main(string[] args)
        {
            Console.WriteLine(ByteToString("D2D4D2D1D6AED0C4A3ACB6B7C6E4D6AED6C741614262436358785A7A"));
            Console.ReadKey();
        }

        static string ByteToString(string str)
        {
            string[] s =System.Text.RegularExpressions.Regex.Replace(str, @"\w{2}", @"$0 ").Trim().Split(' ');
            byte[] bs = new byte[s.Length];
            for (int i = 0; i < s.Length; i++) bs[i] = Convert.ToByte(s[i], 16);
            return Encoding.GetEncoding("GB2312").GetString(bs);
        }

多给些例子才好推测。

[Wesley]

  using   System.Text;  
   
  string   GetValue(string   sHex)  
  {  
      StringBuilder   sb   =   new   StringBuilder();  
      Encoding   enc   =   Encoding.GetEncoding("GB2312");  
      for(int   i=0;   i   <   sHex.Length   -   3;   i   +=4)  
      {  
  string   sub   =   sHex.Substring(i,4);  
   
  //byte   order   is   wrong,   need   to   do   a   switch  
  sub   =   sub.Substring(2,2)   +   sub.Substring(0,2);  
   
  int   c   =   int.Parse(sub,System.Globalization.NumberStyles.HexNumber);  
  byte[]   bs   =   BitConverter.GetBytes(c);  
   
  sb.Append(enc.GetString(bs));  
      }  
   
      return   sb.ToString();  
  }  
   
   
  Console.Write(GetValue("B2DDD2B6"));

这也是我引用别人的，希望对LZ有帮助

[我自横刀香甜笑]

这个需要用加密狗的解密方法吧？

[Wesley]

好像这只是对汉字的。。。我也不是很理解，帮顶

[QIHONGWEI_2000_0]

byte []dataBuff; 放十六进制串
string str="";
for(int i=0;i<DataBuff.Length;i++)
{
str=str+Convert.toString(DataBuff[i])
}

回复有分，楼是不是编码引起的？

看来字母很容易啊.

[QIHONGWEI_2000_0]

string GetValue(string sHex)
{

string str="";
Encoding enc = Encoding.GetEncoding("GB2312");
for(int i=0; i < sHex.Length - 3; i +=4)
{
string sub = sHex.Substring(i,4);

//byte order is wrong, need to do a switch
sub = sub.Substring(2,2) + sub.Substring(0,2);

int c = int.Parse(sub,System.Globalization.NumberStyles.HexNumber);
byte[] bs = BitConverter.GetBytes(c);


str=str+enc.GetString(bs).Replace("\0","");
}

return str;
}
