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
------解决方案--------------------------------------------------------
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);
