Comparing files in VS 2013 - console application

Psuedocode...

Open both files
   var line=ReadLineFromFile1
   while(not eof)
      add stripped file name to Firstlist<string>

   line = ReadLineFromFile2
   while(not eof)
      if stripped file is in list, remove from Firstlist
      else add to Secondlist<string>

Close both files
now, all of the files in Firstlist are in the first file, but not the second one
and, all of the files in Secondlist are in the second file, not the first

if you need help on any specific part of that, feel free to post here or ask a new question.  It is all very easily Googled.

Hi LuckyLucks;

The code snippet below should give you what you are looking for.

'Read all the file names and remove directory part and store in array
Dim allFiles As String() = File.ReadAllLines("C:\Working Directory\All.txt") _
                           .Select(Function(f) Path.GetFileName(f)).ToArray()

Dim OtherFiles As String() = File.ReadAllLines("C:\Working Directory\Other.txt") _
                             .Select(Function(f) Path.GetFileName(f)).ToArray()

' And array of all files in All.txt that are NOT in Other.txt
Dim allNotInOthers As String() = allFiles.Except(OtherFiles).ToArray()
' And array of all files in Other.txt that are NOT in All.txt
Dim otherNotInAll As String() = OtherFiles.Except(allFiles).ToArray()

Select allOpen in new window

Hi LuckyLucks;

In your question you have VB code snippet but in the question tag you have .Net and C#. If you need to have the code translated to C# please let me know.
