c# - Maximize/Minimize Form With Two KeyDown Methods Not Working -

i'm attempting wpf form maximize or minimize when "enter" pressed. however,when debugging, doesn't work.
can write can minimize not maximize, not able both once 1 action performed.
if push me in right direction, appreciated.
i'm using "enter" placeholder combination of 2 keys haven't decided yet. may annoying some, know, works me @ moment.
also, i'm attempting make general overlay program can run in background , can pop when key combination pressed.

private void mainwindow_keydown(object sender, keyeventargs e) {     if (this.windowstate == windowstate.minimized)     {         if (e.key == key.enter)         {             this.windowstate = windowstate.maximized;         }     } } private void mainwindow_keydown2(object sender, keyeventargs e) {     if (this.windowstate == windowstate.maximized)     {          if (e.key == key.enter)          {              this.windowstate = windowstate.minimized;          }      } } 

try this

private void mainwindow_keydown(object sender, keyeventargs e) {             if (e.key == key.enter)     {          if (this.windowstate == windowstate.minimized)          {              this.windowstate = windowstate.maximized;          }          else          {              this.windowstate = windowstate.minimized;          }     } }
