How to display Progress Bar while application is in operation?

[C# Programming]

Hi,

I have windows app that uploads multiple files from a folder into the database. it takes a few seconds to upload all the files. what I need to do is to display a progress bar for the users to see that the application is still busy uploading the files to the database. I don't know how to do that in C# using Progress Bar control.

Please, can you help or advice on what to do.

Thanks.
