C#中Base64之编码,解码方法

编码
publicstringEncodeBase64(stringcode_type,stringcode)
{
stringencode="";
byte[]bytes=Encoding.GetEncoding(code_type).GetBytes(code);
try
{
encode=Convert.ToBase64String(bytes);
}
catch
{
encode=code;
}
returnencode;
}
解码
publicstringDecodeBase64(stringcode_type,stringcode)
{
stringdecode="";
byte[]bytes=Convert.FromBase64String(code);
try
{
decode=Encoding.GetEncoding(code_type).GetString(bytes);
}
catch
{
decode=code;
}
returndecode;
}
