dont show save file window

Question

Hi, currently i am downloading files from client site manually, what i want is to write an application in wpf to download files automatically, on a click of button.

I have been successfully reached to the page where links to the files are given.

Now, my problem is , I don't want to show the save file dialogue box, instead it should save file directly to destination path which i will give in path one by one?

It will make a lot difference in time rather than saving file manually.
