I've searched and found only how to get a certain extension(like txt.). I need to get all of the extensions and print them on the console. How is that possible?
var dir = new DirectoryInfo(@"C:\Random\");
var allExtensions = dir.EnumerateFiles().Select(f => f.Extension).Distinct();
foreach (string ext in allExtensions)
Console.WriteLine(ext);
Use this if you want to list all extensions also in sub-directories:
var allExtensions = dir.EnumerateFiles("*.*", SearchOption.AllDirectories)
.Select(f => f.Extension)
.Distinct();
