Determine number of files in a directory

Question

I need to determine the number of files/subdirectories in a directory. I don't care which files/directories are actually in that directory. Is there a more efficient way than using

_directoryInfo.GetDirectories().Length +
_directoryInfo.GetFiles().Length

Thanks.

Answer 1

That's probably about as good as it gets, but you should use GetFileSystemInfos() instead which will give you both files and directories:

_directoryInfo.GetFileSystemInfos().Length

Answer 2

string[] filePaths = Directory.GetFiles(@"c:\MyDir\");

then just take the size of the filePaths array
