How to free WPF resources after using

Question

Hi all

I used a image as user avatar at the first time my application was loaded. After that, user can change their avatar. But the problem is that after using a new avatar user cannot delete old avatar. The error message show that : "file access denied". That means my application is still using old image somewhere but I don't know.

My question is how to free WPF resource after using it. I have took around google but get nothing

please help me!

thanks

You usually have to call Dispose() on class instances after use to free resources. Even better is to use the using statement that implicitly calls Dispose() like this:

using (FileStream fsSource = new FileStream(pathSource, FileMode.Open, FileAccess.Read))
{
    // Load file content
}
