c# - How do I fix this 'no overload for pictureBox_1 matches delegate 'System.Event.Handler'' -

i have been trying teach myself c# through tutorials , website , didn't know how make "character" move using arrow keys copied code here hoping work , fine until run , throws me error

error 1 no overload 'picturebox1_click' matches delegate 'system.eventhandler' c:\users\collin\documents\visual studio 2013\projects\my_rpg\my_rpg\form1.designer.cs 80 39 my_rpg

here code copied (i did change name whatever picturebox1 correct"

public mainscreen()     {         initializecomponent();         keydown += new keyeventhandler(mainscreen_keydown);         if (charactercreated == false)         {             playgamebtn.forecolor = color.gray;          }     } private void picturebox1_click(object sender, keyeventargs e)     {         int x = picturebox1.location.x;         int y = picturebox1.location.y;          if (e.keycode == keys.right)         {             x += 2;         }         else if (e.keycode == keys.left)          {             x -= 2;         }         else if (e.keycode == keys.up)         {             y += 2;         }         else if (e.keycode == keys.down)         {             y -= 2;         }          picturebox1.location = new system.drawing.point(x, y);      } 

and if click on error sends me line of code if edit throws me errors

        this.picturebox1.click += new system.eventhandler(this.picturebox1_click); 

the signature picturebox click event wants method receives object , eventargs parameter.

your code declares picturebox_click method object , keyeventargs. of course compiler not happy , tells not should be.

from code, seems want handle keydown event @ form level, need change code have method handle keydown event , restore original signature picture box

public mainscreen() {     initializecomponent();     keydown += new keyeventhandler(mainscreen_keydown);     if (charactercreated == false)     {         playgamebtn.forecolor = color.gray;      } } private void picturebox1_click(object sender, eventargs e) {      // remove code event , move mainscreen_keydown  event } private void mainscreen_keydown(object sender, keyeventargs e) {      int x = picturebox1.location.x;     int y = picturebox1.location.y;      if (e.keycode == keys.right)     {         x += 2;     }     else if (e.keycode == keys.left)      {         x -= 2;     }     else if (e.keycode == keys.up)     {         y += 2;     }     else if (e.keycode == keys.down)     {         y -= 2;     }      picturebox1.location = new system.drawing.point(x, y); } 

also, keep in mind, receive keydown events @ form level need set form.keypreview property true
