C＃实现Base64编码与解码（二）

编码

public string EncodeBase64(string code_type,string code)

{

string encode = "";

byte[] bytes = Encoding.GetEncoding(code_type).GetBytes(code);

try

{

encode = Convert.ToBase64String(bytes);

}

catch

{

encode = code;

}

return encode;

}

解码

public string DecodeBase64(string code_type,string code)

{

string decode = "";

byte[] bytes = Convert.FromBase64String(code);

try

{

decode = Encoding.GetEncoding(code_type).GetString(bytes);

}

catch

{

decode = code;

}

return decode;

}
