c# - How to programmatically discover mapped network drives on system and their server names?

Question

I'm trying to find out how to programmatically (I'm using C#) determine the name (or i.p.) of servers to which my workstation has current maps. In other words, at some point in Windows Explorer I mapped a network drive to a drive letter (or used "net use w: " to map it). I know how to get the network drives on the system:

DriveInfo[] allDrives = DriveInfo.GetDrives();
foreach (DriveInfo d in allDrives)
{
    if (d.IsReady && d.DriveType == DriveType.Network)
    {
    }
}

But the DriveInfo class does not have properties that tell me what server and shared folder the mapped drive is associated with. Is there somewhere else I should be looking?

Have you tried to use WMI to do it?

using System;
using System.Management;
using System.Windows.Forms;

public static void Main()
{
    try
    {
        var searcher =  new ManagementObjectSearcher(
            "root\CIMV2",
            "SELECT * FROM Win32_MappedLogicalDisk"); 

        foreach (ManagementObject queryObj in searcher.Get())
        {
            Console.WriteLine("-----------------------------------");
            Console.WriteLine("Win32_MappedLogicalDisk instance");
            Console.WriteLine("-----------------------------------");

            else
            {
                UInt16[] arrPowerManagementCapabilities = (UInt16[])(queryObj["PowerManagementCapabilities"]);
                foreach (UInt16 arrValue in arrPowerManagementCapabilities)
                {
                    Console.WriteLine("PowerManagementCapabilities: {0}", arrValue);
                }

    catch (ManagementException ex)
