This C# code snippet allows you to obtain the free space of a networked drive using System.Management and WMI. It's important to note that the free space could be incorrect when user-quotas are applied.

using System;
using System.Management;
 
class NetworkSpace
{
  static void Main(string[] args)
  {
    SelectQuery query = new SelectQuery(
        "select name, FreeSpace from win32_logicaldisk where drivetype=4");
    ManagementObjectSearcher searcher = new ManagementObjectSearcher(query);
 
    foreach (ManagementObject mo in searcher.Get())
    {
      Console.WriteLine("Drive letter is: {0}", mo["name"]);
      Console.WriteLine("Drive's free space is: {0}", mo["FreeSpace"]);
    }
 
    // Here to stop app from closing
    Console.WriteLine("\nPress Return to exit.");
    Console.Read();
  }
}

Note... In order to use the System.Management namespace in .NET 2, you will need to add a reference to the System.Management.dll. This can be done in the IDE by right-clicking on the project in the solution explorer and choosing Add Reference... from the list. The dll is on the first tab towards the end of the list of items.
