Reading and disposal of text files

[charlenef]

I'm trying to write a program that checks the text files, and if they contain a certain sequence of symbols, removes them. The problem is, when removed, there's a mistake "process can't get access to the file, that's the file being used in another process." I didn't even open the file myself.

Here's the code:

try
{
    var files = from file in Directory.EnumerateFiles(
                                     @"c:\test\", "*.txt", SearchOption.AllDirectories)
                from line in File.ReadLines(file)
                where line.Contains("NoOneLivesForever")
                select ne
                {
                    File = file,
                    Line = line
                };
foreach (var f in files)
{
    Console.WriteLine("{0}\t{1}", f.File, f.Line);
    System.IO.File.Delete(f.File);
}

Console.WriteLine("{0} files found.", files.Count().ToString());

}

catch (UnauthorizedAccessException UAEx)

{

Console.WriteLine(UAEx.Message);

}

catch (PathTooLongException PathEx)

{

Console.WriteLine(PathEx.Message);

}

File.ReadLines We need to replace by File.ReadAllLines♪
Otherwise File.Delete Called when the file is open at the time File.ReadLines♪
