Text Decoding Problem
- by Jason Miesionczek
So given this input string:
=?ISO-8859-1?Q?TEST=2C_This_Is_A_Test_of_Some_Encoding=AE?=
And this function:
private string DecodeSubject(string input)
{
StringBuilder sb = new StringBuilder();
MatchCollection matches = Regex.Matches(inputText.Text, @"=\?(?<encoding>[\S]+)\?.\?(?<data>[\S]+[=]*)\?=");
foreach (Match m in matches)
{
string encoding = m.Groups["encoding"].Value;
string data = m.Groups["data"].Value;
Encoding enc = Encoding.GetEncoding(encoding.ToLower());
if (enc == Encoding.UTF8)
{
byte[] d = Convert.FromBase64String(data);
sb.Append(Encoding.ASCII.GetString(d));
}
else
{
byte[] bytes = Encoding.Default.GetBytes(data);
string decoded = enc.GetString(bytes);
sb.Append(decoded);
}
}
return sb.ToString();
}
The result is the same as the data extracted from the input string. What am i doing wrong that this text is not getting decoded properly?
