Question

I’m working on an application which scans a given networkrange for computers. From the found clients I need to get the IP, hostname, Mac address, OS Information etc.

Now, I have all of the above, except the OS version. Does anyone have a clue on how I could achieve this?

I’m stuck.

Thanks in advance, Christophe

Use WMI, add reference to – System.Management dll and provide namespace, use following code with appropriate parameters-

 ManagementScope scope = new ManagementScope();    
            try
            {                      

                ConnectionOptions conOptions = new ConnectionOptions();  

                options.Username = "<Provide username>";    
                options.Password = "<Provide password>";    
                options.EnablePrivileges = true;    
                options.Authority = "ntlmdomain:<domianname>";                        

                scope = new ManagementScope(@"\\<IP address/machine name>\root\CIMV2", options);

                scope.Connect();                      

                SelectQuery query = new SelectQuery("SELECT * FROM Win32_OperatingSystem");

                ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);

                using (ManagementObjectCollection queryCollection = searcher.Get())
                {    
                    foreach (ManagementObject m in queryCollection)
                    {                            

                        Console.WriteLine(string.Format("Computer Name : {0}", m["csname"]));    
                         Console.WriteLine(string.Format("Windows Directory : {0}", m["WindowsDirectory"]));    
                         Console.WriteLine(string.Format("Operating System: {0}", m["Caption"]));    
                         Console.WriteLine(string.Format("Version: {0}", m["Version"]);

                         Console.WriteLine(string.Format("Manufacturer : {0}", m["Manufacturer"]));

                    }

                }

            }    

            catch (Exception ex)
            {


            }
