c# - Find a file with a certain extension in folder

Question

Given a folder path (like C:Random Folder), how can I find a file in it that holds a certain extension, like txt? I assume I'll have to do a search for *.txt in the directory, but I'm not sure how I'm supposed to start this search in the first place.

Answer 1

Look at the System.IO.Directory class and the static method GetFiles. It has an overload that accepts a path and a search pattern. Example:

 string[] files = System.IO.Directory.GetFiles(path, "*.txt");
