C # Gets the current screen dpi

Original: C # gets the current screen dpi

1. Get through the Graphics class

Graphics currentgraphics = Graphics.fromhwnd (new  windowinterophelper (MainWindow). Handle); double dpixratio = currentgraphics.dpix/;

For example, the current screen setting dpi setting 1.5 times times, can be obtained through the background as above.

2. By Win32-managementclass

using(ManagementClass MC =NewManagementClass ("Win32_DesktopMonitor")){    using(Managementobjectcollection MOC =MC. GetInstances ()) {intPixelsperxlogicalinch =0;//dpi for x        intPixelsperylogicalinch =0;//dpi for y        foreach(ManagementObject eachinchMOC) {Pixelsperxlogicalinch=int. Parse (each. properties["Pixelsperxlogicalinch"].            Value.tostring ())); Pixelsperylogicalinch=int. Parse (each. properties["Pixelsperylogicalinch"].        Value.tostring ())); }    }}

It is worth mentioning that, with the main screen in the case, is not able to get the dpi of the secondary screen!

Note: Physical resolution/real resolution/aspect scaling of the screen, refer to C # API for system DPI zoom and resolution size
