initialization - How to check BitmapImage instance is initialized or not? WPF -

i try use instances of bitmapimage class in circle receive error messages bitmapimage not initialized. how check bitmapimage initialized before use it?

there 2 events commonly used when working bitmaps, 1 fires of when image opened , when image failed;

var myimage = new bitmapimage(new uri(@"images/img.jpeg",urikind.relative));             myimage.imageopened += myimage_imageopened;             myimage.imagefailed += myimage_imagefailed;           void myimage_imagefailed(object sender, exceptionroutedeventargs e)         {             //handle failed event         }          void myimage_imageopened(object sender, routedeventargs e)         {            //handle image opend ok event         }
