c＃复制多个文件

Question

I try to copy multiple files in c# from Folder A to Folder B. I filter the files I want to copy in my Code - after that for example the files 1 , 2 and 5 from Folder A should copy to Folder B. Therefor I want to use the Windows Copy Gui - because I want to see the the copy Progress bar and the Options if any file with the same already name exist.

I´ve found " How to bring up the built-in File Copy dialog? " this article. And I´ve tried to work with the following Options:

Filesystem.CopyFile Filesystem.CopyDirectory

But my Problem is: If I use CopyFile I only can copy ONE File... If I start the CopyFile Statement in loop the Windows Copy GUI will open and close for every file so I cant use the progressbar.

If I use CopyDirectory I only can Copy all files from Folder A to Folder B.

So how can I copy multiple files from Folder A to Folder B with using the WINDOWS COPY GUI ???

Thank you.

It seems you are using VB.Net wrapper over native Windows API and the wrapper limits you. Probably, you can use those (or newer API's) directly and should search into I think you need to use IFileOperation.CopyItems , which accepts array of items as a source, but you'll have to write lots of interop code or find other samples.
