you may use the Windows API method belowWORD GetLogicalDriveStrings(
DWORD nBufferLength,
LPTSTR lpBuffer
);

You can use WMI

Here is an example:

/* CODE BEGIN */
using System;
using System.Management;

public class network
{
public static void Main()
{
SelectQuery query = new SelectQuery( "select name, FreeSpace from
win32_logicaldisk where drivetype=3" );
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( "\n\nPress Return to exit." );
Console.Read();
}
}
/* CODE END */


I have an example app here for network drives.
