asp base64类库，asp.net可解码

　　网上找的asp baes64编码类库，如下面这种结构的，asp.net中无法解码，只能用对应的vbs解码或者自己写解码函数，兼容性不好

 

 const BASE_64_MAP_INIT = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/"
   dim newline
   dim Base64EncMap(63)
   dim Base64DecMap(127)
   '初始化函数
   PUBLIC SUB initCodecs()
'。。。。
   END SUB
   'Base64加密函数
   PUBLIC FUNCTION base64Encode(plain)
'。。。。
   END FUNCTION
   'Base64解密函数
   PUBLIC FUNCTION base64Decode(scrambled)
   END FUNCTION

　　下面这个可以在asp.net中按照常规base64解码方法进行解码

 byte[] bytes = Convert.FromBase64String("base64编码字符串");
Response.Write(encoding.GetString(bytes));
