Hi Dmitry Vitkovsky
I downloaded the file you asked to download but it is also not showing the result which I expected Is there any other way or which can solve my problem. Any way thanks for the reply...
This is my code which is I using to display serial number. It displays all other properties axcept serialnumber.
ManagementObjectSearcher searcher = new ManagementObjectSearcher();
searcher.Query = new ObjectQuery("select * from Win32_PhysicalMedia ");
foreach (ManagementObject obj in searcher.Get())
{
Console.WriteLine(obj["SerialNumber"]);
}
