I find various articles concerning WMI information querries. Both example work the same.<br />

Which code below is better?<br />

I find various articles concerning WMI information querries. Both example work the same.

Which code below is better?

ManagementClass mc = new ManagementClass("Win32_PhysicalMedia");

            foreach (ManagementObject mo in mc.GetInstances())
            {
                listBox1.Items.Add(mo["SerialNumber"].ToString());
            }


ManagementObjectSearcher find = new ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");

            foreach (ManagementObject mo in find.Get())
            {
                listBox1.Items.Add("Serial#... " + mo["SerialNumber"]);                
            }            

ManagementClass vs. ManagementObjectSearcher?

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
