Exclude certain file extensions when getting files from a directory

Question

How to exclude certain file type when getting files from a directory?

I tried

var files = Directory.GetFiles(jobDir);

Answer 1

You can try this,

var directoryInfo = new DirectoryInfo("C:\YourPath");
var filesInfo = directoryInfo.GetFiles().Where(x => x.Extension != ".pdb");

Answer 2

I guess you can use lambda expression

var files = Array.FindAll(Directory.GetFiles(jobDir), x => !x.EndWith(".myext"))

Answer 3

I came across this looking for a method to do this where the exclusion could use the search pattern rules and not just EndWith type logic.

e.g. Search pattern wildcard specifier matches:

• * (asterisk) Zero or more characters in that position.
• ? (question mark) Zero or one character in that position.

This could be used for the above as follows.

string dir = @"C:\Temp";
var items = Directory.GetFiles(dir, "*.*").Except(Directory.GetFiles(dir, "*.xml"));

Or to exclude items that would otherwise be included.

string dir = @"C:\Temp";
var items = Directory.GetFiles(dir, "*.txt").Except(Directory.GetFiles(dir, "*HOLD*.txt"));

Answer 4

i used that

Directory.GetFiles(PATH, "*.dll"))

and the PATH is:

public static string _PATH = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
