Question

I have the following method that is executed in a button click:

 private void CopyDirectoriesAndFiles(string source, string target, string[] excludedFolders)
        {

            foreach (string dir in Directory.GetDirectories(source, "*", System.IO.SearchOption.AllDirectories))
                if (!excludedFolders.Contains(dir))
                    Directory.CreateDirectory(target + dir.Substring(source.Length));

            foreach (string file_name in Directory.GetFiles(source, "*.*", System.IO.SearchOption.AllDirectories))
                if (!File.Exists(Path.Combine(target + file_name.Substring(source.Length))))
                    File.Copy(file_name, target + file_name.Substring(source.Length));

        }

The button click has some other methods, but they don’t take very long to run, but even so, how can I show and update a progress bar for each even that is run. I put a textbox, but it only writes to the textbox once it is finished with everything. My button order may looks like this:

InitializeStuff();

CopyFiles();

CleanUp();

A progress bar is not absolutely necessary, although nice. It would be great if I could get my textbox to update at each time a method completed instead of at the very end.

It shouldn’t be. This will freeze your UI for too long.
