Working with environmental variables

The older version of Microsoft Dynamics NAV (version before 2013) has a built-in function called ENVIRON that allows us to collect OS environmental information; unfortunately, it is not compatible with the RoleTailored client. In this recipe, we will build a simple C# class that will help us to achieve the output given by the ENVIRON function.

   using System.Linq;
   using System.Text;
   using System.Management;
   using System.Runtime.InteropServices;
   
   namespace RemoteSystemInfo
   {
       [ClassInterface(ClassInterfaceType.AutoDual)]
       [ProgId("RemoteSystemInfo")]
       [ComVisible(true)]
       public class RemoteSystemInfo
       {
           public string GetSysInfo(string machine, string variable)
           {
               ManagementObjectSearcher query = null;
               ManagementObjectCollection...
