Image Dispose not working

Question

I have the following code:

 private void picturebox_Paint(object sender, PaintEventArgs e)
 {
   System.Drawing.Image tmp = img[selected].RenderImage(0); //This creates an Image object
   e.Graphics.Clear(System.Drawing.Color.Black);
   e.Graphics.DrawImage(tmp, movingPoint.X, movingPoint.Y, 512, 512);
   tmp.Dispose();
 }

This triggers when the user press PageDown, it basically displays the next image in list.

Now, I see my application memory going up and up and barely decreasing in regular intervals.

Am I disposing the tmp Image correctly? I think that's what is causing my memory issues.

Thanks.

Answer 1

Try:

tmp = nothing (or null - my VB and c# gets confused)

or

gc.collect()

which will force it to clear.
