I am using Directory.EnumerateFiles() and Directory.GetFiles() to get the count of files in a specific directory in c#. The problem is that theses methods are slow because they enumerate files to get there count.
How to get the count of files in Directory without enumerating files in c#?
You have to enumerate through the folder in order to get all the files.
However, you can still do something to improve the performance. I suggest you have a look at those benchmark tests (Get1 method):

It seems like the following method provides the best performance, according to the benchmark test:
private static int Get1(string myBaseDirectory) { DirectoryInfo dirInfo = new DirectoryInfo(myBaseDirectory); return dirInfo.EnumerateDirectories() .AsParallel() .SelectMany(di => di.EnumerateFiles("*.*", SearchOption.AllDirectories)) .Count(); } I actually never tried a faster way but its a good question.. By searching I've found this

The Benchmark comparison looks quite nice..
MayBe this helps..
hi maybe this help it return string[]
String[] files = Directory.GetFileSystemEntries("path"); I think you have to use Directory.GetFiles() or the DirectoryInfo class.
The Advantage is, that you can use an overload of GetFIles to search for files inside subdirectories e.g.
int allfilesCount = Directory.GetFiles(path, "*", SearchOption.AllDirectories).Length; Mybe you could try
Directory.EnumerateFiles().Count() if it is faster.
