How to exclude certain file type when getting files from a directory?
I tried
var files = Directory.GetFiles(jobDir);
But it seems that this function can only choose the file types you want to include, not exclude.

2@TarmoPikaro, I think it is another way round . Your question is a dupe of mine.Graviton– Graviton2016-05-27 09:15:56 +00:00Commented May 27, 2016 at 9:15

You should filter these files yourself, you can write something like this:
var files = Directory.GetFiles(jobDir).Where(name => !name.EndsWith(".xml"));

As far as i now the EndsWith takes capital letters into account, which means that if the filetype would be .XML it would not exclude it.
doog abides
var files = Directory.GetFiles(jobDir).Where(name => !name.EndsWith(".xml", true));

var files = Directory.GetFiles(jobDir).Where(name => !name.EndsWith(".xml", StringComparison.OrdinalIgnoreCase));M. Fawad Surosh
Worked for me. I just had to add .ToList(); at the end because my variable was a list :)

@m-fawad-surosh Thanks, good comment, I needed a slightly different variant, since the original
GetFiles returns string[] and I wanted to keep my code with the same convention, I just did a call similar to: Directory.GetFiles(jobDir).Where(...).ToArra(), there are more such options! |
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)));
}

I was looking a LINQ way to exclude multiple extensions. I found it here. Thank you very much.
You could try something like this:
var allFiles = Directory.GetFiles(@"C:\Path\", "");
var filesToExclude = Directory.GetFiles(@"C:\Path\", "*.txt");
var wantedFiles = allFiles.Except(filesToExclude);

This works brilliantly in all forms of the GetFiles() command. It doesn't solve the question precisely but you get the added benefit of leveraging the searchPattern parameter, which is much more powerful than just looking at extensions.

Advice: this won't work with the instance method
DirectoryInfo.GetFiles(): it returns an array of FileInfo (instead string), a non-comparable/non-equatable class.

This solution is good for multi pattern file exclusion. Thanks

This will require folder enumeration twice with 2 sets of filters.. Better to play on string arrays only
I guess you can use lambda expression
var files = Array.FindAll(Directory.GetFiles(jobDir), x => !x.EndWith(".myext"))

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

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);
}
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>();

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"));

i used that
Directory.GetFiles(PATH, "*.dll"))
and the PATH is:
public static string _PATH = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
