Requirements: such as a host, open 4 forms, outside the 3 monitors, click the program button, directly the other 3 forms, respectively, to maximize the display on the other display

Roughly wrong impression, but can learn the principle:

Today's needs:

Wrong idea:

Get the Display object, and then show in this display, hey ~aaronyang tell you, this is a no return!

Correct thinking Steps:

1. As long as you understand all the screen expansion, it will be a large screen, each screen is an object, according to this object can get the information of each monitor

2. Each extended display has a workarea area

3. Place the show time of window equal to the position of the monitor

4. Turn off all screen projection displays, just temporarily remember the window and loop close to

：

3 Forms, one home screen form, for manipulating

Core code:

screen[] Screens =Screen.allscreens; if(screens. Length = =1) {lblmsg. Content="1 displays have been projected"; }            Else if(screens. Length = =2) {lblmsg. Content="2 displays have been projected"; }            Else if(screens. Length = =4) {lblmsg. Content="4 displays have been projected"; }            Else{lblmsg. Content="currently only supports 1,2,4 display modes"; }            //Home Screen DisplayScreen Mainscreen = screens. FirstOrDefault (x=>x.primary==true); //Home Screen Display Window1Window1 win1 =NewWindow1 (); Win1. WindowState=windowstate.maximized; Win1. Windowstartuplocation=windowstartuplocation.manual; System.Drawing.Rectangle Mswa=Mainscreen.workingarea; Win1. Left=Mswa.            Left; Win1. Top=Mswa.            Top; Win1. Width=Mswa.            Width; Win1. Height=Mswa.            Height;            Openwindows.add (win1); Win1.            Show (); //other screens are shown here, assuming there are 2            varSubscreen = ( fromOinchScreenswhereO.primary = =false SelectO). Tolist<screen>(); if(Subscreen.count >0) {                varSubscreen1 = subscreen[0]; Window2 win2=NewWindow2 (); Win1. WindowState=windowstate.maximized; Win1. Windowstartuplocation=windowstartuplocation.manual; System.Drawing.Rectangle MSWA2=Subscreen1.                Workingarea; Win2. Left=mswa2.                Left; Win2. Top=mswa2.                Top; Win2. Width=mswa2.                Width; Win2. Height=mswa2.                Height;                Openwindows.add (win2); Win2.            Show (); }
