How to Clear an image control in WPF (C#)

Question

I have an image control with a source image located in my c drive. I get a message that the image is being used by another process whenever I try to delete the original image to change it with another one dynamically. How do I release the image from the image control to be able to delete it.

I tried this variants:

string path = ((BitmapImage)img.Source).UriSource.LocalPath;
img.SetValue(System.Windows.Controls.Image.SourceProperty, null);
File.Delete(path);

And:

string path = ((BitmapImage)img.Source).UriSource.LocalPath;
img.Source = null;
File.Delete(path)

But it's not work...

Try setting the bitmap image through the stream source property. That way the app won't put a lock on the file since you loaded it through a stream.
