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("-----------------------------------");             Console.WriteLine("Access: {0}", queryObj["Access"]);             Console.WriteLine("Availability: {0}", queryObj["Availability"]);             Console.WriteLine("BlockSize: {0}", queryObj["BlockSize"]);             Console.WriteLine("Caption: {0}", queryObj["Caption"]);             Console.WriteLine("Compressed: {0}", queryObj["Compressed"]);             Console.WriteLine("ConfigManagerErrorCode: {0}", queryObj["ConfigManagerErrorCode"]);             Console.WriteLine("ConfigManagerUserConfig: {0}", queryObj["ConfigManagerUserConfig"]);             Console.WriteLine("CreationClassName: {0}", queryObj["CreationClassName"]);             Console.WriteLine("Description: {0}", queryObj["Description"]);             Console.WriteLine("DeviceID: {0}", queryObj["DeviceID"]);             Console.WriteLine("ErrorCleared: {0}", queryObj["ErrorCleared"]);             Console.WriteLine("ErrorDescription: {0}", queryObj["ErrorDescription"]);             Console.WriteLine("ErrorMethodology: {0}", queryObj["ErrorMethodology"]);             Console.WriteLine("FileSystem: {0}", queryObj["FileSystem"]);             Console.WriteLine("FreeSpace: {0}", queryObj["FreeSpace"]);             Console.WriteLine("InstallDate: {0}", queryObj["InstallDate"]);             Console.WriteLine("LastErrorCode: {0}", queryObj["LastErrorCode"]);             Console.WriteLine("MaximumComponentLength: {0}", queryObj["MaximumComponentLength"]);             Console.WriteLine("Name: {0}", queryObj["Name"]);             Console.WriteLine("NumberOfBlocks: {0}", queryObj["NumberOfBlocks"]);             Console.WriteLine("PNPDeviceID: {0}", queryObj["PNPDeviceID"]);              if(queryObj["PowerManagementCapabilities"] == null)                 Console.WriteLine("PowerManagementCapabilities: {0}", queryObj["PowerManagementCapabilities"]);             else             {                 UInt16[] arrPowerManagementCapabilities = (UInt16[])(queryObj["PowerManagementCapabilities"]);                 foreach (UInt16 arrValue in arrPowerManagementCapabilities)                 {                     Console.WriteLine("PowerManagementCapabilities: {0}", arrValue);                 }             }             Console.WriteLine("PowerManagementSupported: {0}", queryObj["PowerManagementSupported"]);             Console.WriteLine("ProviderName: {0}", queryObj["ProviderName"]);             Console.WriteLine("Purpose: {0}", queryObj["Purpose"]);             Console.WriteLine("QuotasDisabled: {0}", queryObj["QuotasDisabled"]);             Console.WriteLine("QuotasIncomplete: {0}", queryObj["QuotasIncomplete"]);             Console.WriteLine("QuotasRebuilding: {0}", queryObj["QuotasRebuilding"]);             Console.WriteLine("SessionID: {0}", queryObj["SessionID"]);             Console.WriteLine("Size: {0}", queryObj["Size"]);             Console.WriteLine("Status: {0}", queryObj["Status"]);             Console.WriteLine("StatusInfo: {0}", queryObj["StatusInfo"]);             Console.WriteLine("SupportsDiskQuotas: {0}", queryObj["SupportsDiskQuotas"]);             Console.WriteLine("SupportsFileBasedCompression: {0}", queryObj["SupportsFileBasedCompression"]);             Console.WriteLine("SystemCreationClassName: {0}", queryObj["SystemCreationClassName"]);             Console.WriteLine("SystemName: {0}", queryObj["SystemName"]);             Console.WriteLine("VolumeName: {0}", queryObj["VolumeName"]);             Console.WriteLine("VolumeSerialNumber: {0}", queryObj["VolumeSerialNumber"]);         }     }     catch (ManagementException ex)     {         MessageBox.Show("An error occurred while querying for WMI data: " + ex.Message);     } }

You could use WMI to enumerate and query mapped drives. The following code enumerates mapped drives, extracts the server name portion, and prints that out.

using System; using System.Text.RegularExpressions; using System.Management;  namespace ConsoleApplication1 {     class Program {         static void Main(string[] args) {             ManagementObjectSearcher searcher = new ManagementObjectSearcher(                 "select * from Win32_MappedLogicalDisk");             foreach (ManagementObject drive in searcher.Get()) {                 Console.WriteLine(Regex.Match(                     drive["ProviderName"].ToString(),                     @"\\\\([^\\]+)").Groups[1]);                 }             }         }     } } 

You can find the documentaiton of the Win32_MappedLogicalDisk class here. An intro for accessing WMI from C# is here.
