Hi, I am currently working with Bitmap Images in C# WPF, and I have run into the following problem and I was hoping someone could help. the code below is how I assign a bitmap image to a bitmap and then to a ImageControl. The problem comes in that im using this code for many bitmap images and they seem to stay in memory... How do I remove bitmap images from memory the correct way. Please Help!

C#

BitmapImage logo = new BitmapImage();
          logo.BeginInit();
          logo.CreateOptions = BitmapCreateOptions.IgnoreColorProfile;
          logo.UriSource = new Uri(f.FullName);
          displayImage.Source = logo;
          logo.EndInit();

Thanks in advance :)

Solution 1

By adding the following Code to my project,

logo.DecodePixelWidth = 100;
logo.DecodePixelHeight = 100;

it works alot better and is alot more memory friendly when using around about 700 images :)
