WPF Screen Resolution

Question

I have been working on WPF desktop application and have graphics according to a particular screen resolution. I need to scale the all the margins based on screen resolution. How can I achieve this?

Answer 1

you can use :

System.Windows.SystemParameters.PrimaryScreenWidth;
System.Windows.SystemParameters.PrimaryScreenHeight;

make a little search :)

Answer 2

To get the Screen Resolutions we have to use the dpi factor value of system, use the below code as per this article (please read it in full to understand):

using System.Windows.Media;


Window mainWindow = Application.Current.MainWindow;
PresentationSource mainWindowPresentationSource = PresentationSource.FromVisual(mainWindow);
Matrix m = mainWindowPresentationSource.CompositionTarget.TransformToDevice;
double dpiWidthFactor = m.M11;
double dpiHeightFactor = m.M22;
double ScreenHeight = SystemParameters.PrimaryScreenHeight * dpiHeightFactor; //calculated correct value
double ScreenWidth = SystemParameters.PrimaryScreenWidth * dpiWidthFactor; //calculated correct value

Answer 3

Add reference to :- System.Windows.Forms

var width = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Width;
