C# 4.0 unlock image after creating BitmapImage

问题

I am creating an BitmapImage from an existing image using:

BitmapImage bmp = new BitmapImage();
bmp.BeginInit();
bmp.UriSource = new Uri(jpegPath, UriKind.Relative);
bmp.EndInit();

After I have done this I want to delete the image from my hard drive, but it is locked. Is there a way I can unlock it so it can be removed?

回答1:

bmp.CacheOption = BitmapCacheOption.OnLoad;

That will load the image into memory completely and won't leave a lock on the image file.

回答2:

JPG is still set as the source of existing object in your application. Try to set the source of BitmapImage to something else or remove it completely. Or create a copy of your JPG in memory.
