问题 I have a progress bar to show the status of the program loading songs into the library. foreach (Song s in InitializeLibrary()) { Library.AddSong(s); pBar.Value++; pBar.Update(); } InitializeLibrary() is just a function that returns a List The problem is that the progress bar stops "moving" after a certain point (eg 20%), while the value still increases.
