Get network path not drive letter from FolderBrowserDialog

Question

I have a winform with a FolderBrowserDialog to choose a folder from a network drive. The issue is that it returns the drive letter (X:\Folder...) rather than the network path (\\Network\Projects\Folder...). How can I get the network path?

Answer 1

Quick and dirty code that will show the path as a network path in a MessageBox. You may want to add additional checks and/or restructure this a bit.

using System.Management;

        var dialog = new OpenFileDialog();
        dialog.ShowDialog();

        var path = dialog.FileName;
        using (var managementObject = new ManagementObject())
        {
            managementObject.Path = new ManagementPath($"Win32_LogicalDisk='{path.Substring(0,2)}'");
            var driveType = (DriveType)(uint)managementObject["DriveType"];
            var networkPath = Convert.ToString(managementObject["ProviderName"]);
            

            if (driveType == DriveType.Network)
            {
                MessageBox.Show(path.Replace(path.Substring(0, 3), networkPath));
            }
        }

        MessageBox.Show(path);
