how to programmatically change the background image on form c#

Question

I need to change the background image of my form when i klick a button, and change it back to null again the second time it is clicked, how can i do this?

Answer 1

Use BackgroundImage property:

form.BackgroundImage = image;

to hide the image:

form.BackgroundImage = null;

Put this source code to ClickButton method:

form.BackgroundImage = form.BackgroundImage == null ? image : null;
