另存为对话框C＃

Question

I have one export method which gives me one .txt file. That file is getting saved on Downloads on my machine.

I want one save as pop up which ask user where they want to save that downloaded file, as well as they can name the file.

Answer 1

I assume you mean the situation where the browser is automatically saving the file and not asking where to save it?

This is controlled by the Content-Disposition header (19.5.1). If you add a header like

Content-Disposition: attachment; filename="file.txt"

then the browser understands that it is an attachment and should ask what to do with it.

However, the browser may choose to do something else with it.
