How to get Network drive size in C# (without "map drive")

Question

I need to get the free space of a Network drive, without "map drive"

DriveInfo drvInfo = new DriveInfo("\\NetworkDrive");

I try to do this but it does not work.

See http://stackoverflow.com/questions/676734/net-driveinfo-with-unc-paths - DriveInfo doesn't work with UNC paths (it even specifies that in the help). Try @Mitch's suggstion. — Donnie, Jun 03 '10 at 12:16

e.g.

You could use WMI to connect to the remote computer and display the free space for each drive.

An example can be found here
