Comparing two files

Hi I have two files. In 1st file: in 2nd file: [FileVersion] GUID={F5C91E25-E904-4AD0-AA6A-41FD0A5A12E4} Version=9 MarkupVersion=0 DisplayName=XML-MDB-Satzweise-nxt FileExtension=*.xml How can i compare two files Based on GUID. If these two GUID's are equal than two files are the same. Thanks Darma

Assuming there's only one GUID in each file or it's just the first one you need to match then this is easily done using a regular expression. Here's some sample code: using System; using System.IO; using System.Text.RegularExpressions; class Test { static void Main() { string regExp = @(?i)\b + @[0-9A-F]{8}- + @[0-9A-F]{4}- + @[0-9A-F]{4}- + @[0-9A-F]{4}- + @[0-9A-F]{12} + @\b; string text = File.ReadAllText(darma.xml); string guid = Regex.Match(text regExp).Value; Console.WriteLine(guid); string text2 = File.ReadAllText(darma.ini); string guid2 = Regex.Match(text2 regExp).Value; Console.WriteLine(guid2); if (guid == guid2) Console.WriteLine(Files are the same); else Console.WriteLine(Files are not the same); Console.ReadKey(); } }
