Dynamically retrieving WMI Data - A little help please!
-
Hi there, i get an exception while using C# and wmi to retrieve some data. So here is the code is wrote:
public class Adapter { public static ManagementObjectCollection GetNicAdapters() { try { WqlObjectQuery WQO = new WqlObjectQuery("SELECT * FROM Win32_NetworkAdapter WHERE NetConnectionStatus != null"); ManagementObjectSearcher MOS = new ManagementObjectSearcher(WQO); ManagementObjectCollection MOC = MOS.Get(); return MOC; } catch (Exception ex) { MessageBox.Show("Data couldn't be retrieved."); return null; } }I use this function to populate a field in my Form1 Base form. On the form (visually) there is a combo box, which now is filled with the Description of the Object. All of this works so far but now i am getting problems:private void comboBox1_SelectedIndexChanged(object sender, EventArgs e) { if (Adapters != null) { try { ManagementObject[] MOArray = new ManagementObject[Adapters.Count]; Adapters.CopyTo(MOArray, 0); int select = comboBox1.SelectedIndex; int selectedIndex = int.Parse(MOArray[select]["Index"].ToString()); int status = int.Parse(MOArray[select]["NetConnectionStatus"].ToString()); string myQueryString = "SELECT * FROM Win32_NetworkAdapterConfiguration WHERE Index = " + selectedIndex.ToString(); WqlObjectQuery ConfigQuery = new WqlObjectQuery(myQueryString); ManagementObjectSearcher ConfigSearcher = new ManagementObjectSearcher(ConfigQuery); ManagementObjectCollection ManagementObjectConfigurations = ConfigSearcher.Get(); ManagementObject[] CurrentArray = new ManagementObject[ManagementObjectConfigurations.Count]; ManagementObjectConfigurations.CopyTo(CurrentArray, 0); ManagementObject CurrentConfig = CurrentArray[0]; #region Draw Status IconConverter IC = new IconConverter(); switch (status) { case 0: l_status.Text = "Gerät nicht angeschlossen";
