C# make background image fit the screen?

I decided to add a background image to my winforms application and I wonder how I can make the background always fit with the screen? (auto-stretch it).

I have a form where users can resize it and choose their own window size, but I want the background to always fill the application. I have a huge background wallpaper, about 2000x1500 in resolution, if the user resize the form window to about 500x500 it will only show a small part of the wallpaper, how can I make it show the full wallpaper but in a smaller resolution?

I haven't found anything about this and I have no idea where to even start. Could anyone help me?

        BackgroundImage = System.Drawing.Image.FromFile("C:\\Users\\Downloads\\2137969.png");
        this.BackgroundImageLayout = System.Windows.Forms.ImageLayout.Stretch;
    }

Set the BackgroundImageLayout() property of the Form to either "Stretch" or "Zoom".

Just set the forms BackgroundImageLayout to Stretch.

This will probably cause flickering, to prevent this you can (in the ctor):

this.SetStyle(
    ControlStyles.AllPaintingInWmPaint |
    ControlStyles.DoubleBuffer,
    true);
