c# - attempting to cycle between three images when if statement is met -

i have 4 if statements in code change displays. on if statement inqueueinring > 10 cycle every .5 seconds between red, yellow, , green images until condition no longer true. i'm not sure start cycling images. list image source multiple times thread.sleep(1000) in between them?

i tried use loading new image each second can't convert type system.threading.timer system.windows.media.imagesource. updated code below.

below if statements

    if (e.cmsdata.skill.agentsavailable > 0)     {         dispatcher.begininvoke(dispatcherpriority.normal, (action)(() =>         {             callswaitingdata.text = e.cmsdata.skill.agentsavailable.tostring();             callswaitingdata.foreground = new solidcolorbrush(colors.green);             callswaitingtext.text = "available";             callimgae.source = new bitmapimage(new uri("pack://application:,,,/scoreboardclienttest;component/images/circle_green.png", urikind.absolute));         }));     }     else if (e.cmsdata.skill.inqueueinring > 10)     {         dispatcher.begininvoke(dispatcherpriority.normal, (action)(() =>         {             callswaitingdata.text = e.cmsdata.skill.inqueueinring.tostring();             callswaitingdata.foreground = new solidcolorbrush(colors.red);             callswaitingtext.text = "waiting";             timer = new system.threading.timer(ontimerellapsed, new object(), 0, 2000);         }));     }     else if (e.cmsdata.skill.inqueueinring > 0)     {         dispatcher.begininvoke(dispatcherpriority.normal, (action)(() =>         {             callswaitingdata.text = e.cmsdata.skill.inqueueinring.tostring();             callswaitingdata.foreground = new solidcolorbrush(colors.red);             callswaitingtext.text = "waiting";             callimgae.source = new bitmapimage(new uri("pack://application:,,,/scoreboardclienttest;component/images/circle_red.png", urikind.absolute));         }));     }     else if (e.cmsdata.skill.agentsavailable == 0)     {         dispatcher.begininvoke(dispatcherpriority.normal, (action)(() =>         {             callswaitingdata.text = e.cmsdata.skill.agentsavailable.tostring();             callswaitingdata.foreground = new solidcolorbrush(colors.yellow);             callswaitingtext.text = "available";             callimgae.source = new bitmapimage(new uri("pack://application:,,,/scoreboardclienttest;component/images/circle_yellow.png", urikind.absolute));         }));     }    private void ontimerellapsed(object state)         {             if (!this.dispatcher.checkaccess())             {                 this.dispatcher.invoke(new action(loadimages));             }         }             private void loadimages()         {             string stringuri = switcher ? @"pack://application:,,,/scoreboardclienttest;component/images/circle_red.png" :                                           @"pack://application:,,,/scoreboardclienttest;component/images/circle_yellow.png";                                          // @"pack://application:,,,/scoreboardclienttest;component/images/circle_green.png";             this.callimgae.source = new bitmapimage(new uri(stringuri));              switcher = !switcher;         }   

so can't see rest of code, if going use these images sure pre-load or cache them somewhere before doing kind of operation (for performance).

there plenty of threading/process classes can use bare bones 1 enjoy using thread class. here how set thread..

thread mythread = new thread(threaddelegate); 

the threaddelegate of class threadstart the work want thread do. here 1 way set threaddelegate..

threadstart threaddelegate = new threadstart(() => {     while (iscycling == true)     {         // code here         thread.sleep(1000);     } }); 

the iscycling loop stop on condition after odd cycles or prematurely exit. can make thread start delegate/work gave using start method..

mythread.start(); 

if want parent thread (i.e. main thread) wait thread stop or not move on until cycling done can use join method on mythread.
