Delete files from directory if filename contains a certain word

Question

I need to check a directory to see if there are any files whose file name contains a specific keyword and if there are, to delete them. Is this possible?

Answer 1

You can use System.IO.Directory.GetFiles() to a list of the files, in string[] format.

Then you can use System.IO.File.ReadAllText() to read complete files, or if they are very big, open a TextReader with System.IO.File.OpenText().

If you are looking for a literal keyword, String.Contains() is all you need.

Deleting a file can be done with System.IO.File.Delete(). Make sure the file is closed again.

Edit, 2 examples of GetFiles():

string[] fileNames = System.IO.Directory.GetFiles(@"C:\");
string[] fileNames = System.IO.Directory.GetFiles(@"C:\", @"*.sys");
