Find number of files with a specific extension, in all subdirectories

Question

Is there a way to find the number of files of a specific type without having to loop through all results inn a Directory.GetFiles() or similar method? I am looking for somet

Answer 1

I was looking for a more optimized version. Since I haven't found it, I decided to code it and share it here:

    public static int GetFileCount(string path, string searchPattern, SearchOption searchOption)
    {
        var fileCount = 0;
        var fileIter = Directory.EnumerateFiles(path, searchPattern, searchOption);
        foreach (var file in fileIter)
            fileCount++;
        return fileCount;
    }

All the solutions using the GetFiles/GetDirectories are kind of slow since all those objects need to be created. Using the enumeration, it doesn't create any temporary objects (FileInfo/DirectoryInfo).
