问题
I have a Windows Universal App which uses several BitmapImages. I'm used to wrapping Bitmaps (in Winforms) in usings or using Dispose, but I've discovered that BitmapImage doesn't have a Dispose method. Is there any way to release their resources earlier than waiting for the GC to do that?
回答1:
Here's a good solution : Memory consumption of BitmapImage/Image control in Windows Phone 8 . it's like a extension 'Dispose' method for the BitmapImage
And yes, GC.Collect() is good way ..
