  • Hi,

    I am using the 'CurrentBrightness' property value for and a setting the value. but i see the value returned is wrong from the API.

  • Hi,

    Here is a simple sample which use ManagementScope for your reference.

    //create a management scope object
    ManagementScope scope = new ManagementScope("\\\\.\\ROOT\\WMI");
    
                //create object query
                ObjectQuery query = new ObjectQuery("SELECT * FROM WmiMonitorBrightness");
    
                //create object searcher
                ManagementObjectSearcher searcher =
                                        new ManagementObjectSearcher(scope, query);
    
                //get a collection of WMI objects
                ManagementObjectCollection queryCollection = searcher.Get();
    
                //enumerate the collection.
                foreach (ManagementObject m in queryCollection)
                {
                    // access properties of the WMI object
                    Console.WriteLine("CurrentBrightness : {0}", m["CurrentBrightness"]);
    
                }

    Best regards,
