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 sea

Answer 1

The method below returns only the files with certain extension (eg: file with .txt but not .txt1)

public static IEnumerable GetFilesByExtension(string directoryPath, string extension, SearchOption searchOption)
    {
        return
            Directory.EnumerateFiles(directoryPath, "*" + extension, searchOption)
                .Where(x => string.Equals(Path.GetExtension(x), extension, StringComparison.InvariantCultureIgnoreCase));
    }
