C # The Custom position is displayed in the form. Any position is displayed. The form is displayed below the screen.

As required by the project, the position of the form to be opened must be in the lower right corner of the screen, so the default position cannot be solved, so the display position can be customized and can be set to any position.
My form is 240x109 in size and is opened in the lower right corner of the monitor.

Int widthlocation = system. Windows. Forms. Screen. primaryscreen. workingarea. Size. Width-240;
Int heightlocation = system. Windows. Forms. Screen. primaryscreen. workingarea. Size. Height-109;
This. setdomaintoplocation (widthlocation, heightlocation );

You can set any display position based on the size of your form.

Below the form display screen, on the left of the form display screen, on the right of the form display screen, on the top of the form display screen can be customized
