C#中Base64之編碼,解碼方法

編碼
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;
}
解碼
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;
}
