Get and Set Screen Resolution

Question

How can I collect and change screen resolution using Visual C#?

Answer 1

I have spent a lot of time trying to figure this out, for devices with scaling factor is very difficult to get the actual size of the screen due to the scaling factor sometimes 125% or 150% when the calls are made to the C# objects the returning value is not the right now, so you need to make a windows API call to get the scaling factor and apply the multiplier, the only working way that I have found for non WPF apps is here
