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

This is my version on the answers I read above

List<FileInfo> fileInfoList = ((DirectoryInfo)new DirectoryInfo(myPath)).GetFiles(fileNameOnly + "*").Where(x => !x.Name.EndsWith(".pdf")).ToList<FileInfo>();

Answer 2

Afaik there is no way to specify the exclude patterns. You have to do it manually, like:

string[] files = Directory.GetFiles(myDir);
foreach(string fileName in files)
{
    DoSomething(fileName);
}

Answer 3

string[] filesToDelete = Directory.GetFiles(@"C:\Temp", "*.der");

foreach (string fileName in filesToDelete)
{
    File.Delete(fileName);
}

Answer 4

I know, this a old request, but about me it's always important.

if you want exlude a list of file extension: (based on https://stackoverflow.com/a/19961761/1970301)

var exts = new[] { ".mp3", ".jpg" };



public IEnumerable<string> FilterFiles(string path, params string[] exts) {
    return
        Directory
        .GetFiles(path)
        .Where(file => !exts.Any(x => file.EndsWith(x, StringComparison.OrdinalIgnoreCase)));
}

Answer 5

You could try something like this:

  var allFiles = Directory.GetFiles(@"C:\Path\", "");
  var filesToExclude = Directory.GetFiles(@"C:\Path\", "*.txt");
  var wantedFiles = allFiles.Except(filesToExclude);

Answer 6

You should filter these files yourself, you can write something like this:

    var files = Directory.GetFiles(jobDir).Where(name => !name.EndsWith(".xml"));
