Question:
What I'm trying do is read all the text in a file and if it contains the word "Share" do a regex. Here is the code:
DirectoryInfo dinfo = new DirectoryInfo(@"C:\Documents and Settings\g\Desktop\123"); FileInfo[] Files = dinfo.GetFiles("*.txt"); foreach (FileInfo filex in Files) { string contents = File.ReadAllText(filex.FullName); string matchingcontants = "Share"; if (contents.Contains(matchingcontants)) { string sharename = Regex.Match(contents, @"\+(\S*)(.)(.*)(.)").Groups[3].Value; File.AppendAllText(@"C:\sharename.txt", sharename + @"\r\n"); } } When I debug I get... contents = "\r\0\n\0=\0=\0=\0=\0=\0=\0=\0=\0=\0=\0=\0=\0=\0=\0=\0=\0=\0=\0=\0=\0=\0=\0=\0=\0=\0=\0=\0=\0=\0\r\0\n\0+\0S\0h\0a\0r\0e\0 \0\\0\\0j\05\02\0\\0w\0w\0w\0_\0O\0n\0t\
\0S\0h\0a\0r\0e\
Not Share. Any hints? tips or suggestions?
Solution:1
Looks like you've got a file which is saved as UTF-16 (i.e. Encoding.Unicode). Read the file with the right encoding, and all should be well.
Fortunately there's an overload of File.ReadAllText which takes an encoding:
string contents = File.ReadAllText(filex.FullName, Encoding.Unicode); Unfortunately, that will then do the wrong thing for files which aren't in UTF-16. While there are heuristic ways of guessing the encoding, ideally you should know the encoding before you open the file.
Solution:2
Looks like it's a Unicode file, and you're trying to read it as plain ASCII.
Solution:3
My guess is that the encoding is not set correctly, you might need to use ReadAllText(String, Encoding) specifying the encoding.
