C#怎样把浮点数的十六进制化成十进制数
例如我有十六进制数：47 7A 45 C2,十进制数是：-49.3694 ；如何用C# 把他化成十进制数？求具体代码

[解决办法]
这样就行了：

C# code

        string s = "477A45C2";        MatchCollection matches = Regex.Matches(s, @"[0-9A-Fa-f]{2}");        byte[] bytes = new byte[matches.Count];        for (int i = 0; i < bytes.Length; i++)            bytes[i] = byte.Parse(matches[i].Value, NumberStyles.AllowHexSpecifier);        float m = BitConverter.ToSingle(bytes, 0);        Response.Write(m);
