I am writing a program that will play a slideshow (among other things). The slideshow is controlled by a backgroundWorker, and is set to a while(true) loop so it will constantly play images. My problem is I'm not sure how to dispose of the old images so they don't take up memory (after a while the program throws an "Out of memory exception). If I call horPicBox.Image.Dispose() then it won't let me use the pictureBox at all after that.
Is there a way to release the old image from memory?? If I look at the diagnostic tools in VS, the memory goes up each time the image changes ...
Note: ImagePaths is a List of the filepaths for the slideshow images.
This is the code the backgroundWorker runs:
private void PlayImages()
{
Random r = new Random();
int index;
Stopwatch watch = new Stopwatch();
while (true)
{
index = r.Next(imagePaths.Count);
horPicBox.Image = Image.FromFile(imagePaths[index]);
watch.Start();
while (watch.ElapsedMilliseconds < 5000)
{
}
watch.Stop();
watch.Reset();
//picWorker.ReportProgress(0);
}
}
I can report progressChanged to the UI thread, but I'm not sure what I need to do from the UI thread (if anything) to release the old Image(s). Thanks in advance!!
