Can't get OEMStringArray

[Martin Balaj]

Trying to get OEMStringArray from WMI and use it as Text, but result is still empty textbox. Looks like ouput is string[].
command like "wmic computersystem get oemstringarray" works
Sorry, I'm newbie programmer.

Tried:

      ManagementObjectSearcher mc7 = new ManagementObjectSearcher("SELECT * FROM Win32_ComputerSystem");
      ManagementObjectCollection moc7 = mc7.Get();
      if (moc7.Count != 0)
         {
             foreach (ManagementBaseObject mo7 in moc7)
                {
                textBox7.Text = mo7["OEMStringArray"].ToString();
 
                }
          } 

And also:

            ManagementClass mc3 = new ManagementClass("Win32_ComputerSystem");
            ManagementObjectCollection moc3 = mc3.GetInstances();
            if (moc3.Count != 0)
            {
                foreach (ManagementObject mo3 in mc3.GetInstances())
                {
 
                    textBox7.Text = mo3["OEMStringArray"].ToString();
 
                 }
             }   
 

Some of this:

                    ...
                    string[] stringArray = mo5["OEMStringArray"] as String[];
                    foreach (string myString in stringArray)
                    {
                    listBox2.Items.Add(stringArray);
                    }
 

Any ideas ?
