Querying the registry

You must be thinking, "Why do we need to query the registry with NAV?" Just take this recipe as an option.

How to do it...

1. Let's create a new Class Library project in Visual Studio.

2. Create a new file in the class with the following code:

   using System;
   using System.Collections.Generic;
   using System.Linq;
   using System.Text;
   using System.Runtime.InteropServices;
   using Microsoft.Win32;
   
   namespace RegistryQuery
   {
       [ClassInterface(ClassInterfaceType.AutoDual)]
       [ProgId("RegistryQuery")]
       [ComVisible(true)]
       public class RegistryQuery
       {
           public string GetKeyValue(string key, string name)
           {
               RegistryKey regKey = Registry.Users.OpenSubKey(key);
               if (regKey == null)
               {
                   return "Key not found!";
               }
               else
               {
                   object value = regKey.GetValue(name);
                   if (value != null)
                   {
                       return value.ToString();
                ...
