What code i have to do ? Can i use WebClient for the same ?

Answer 1

There is no "Save As" dialog in ASP.NET. Since it is running in a browser. You have no access to the user's file system, including the Save As dialog.

But you can send the user a file, as an attachment, most browsers will display a dialog asking the user whether to save the file or open it. Maybe the user will choose to save it.

Response.ContentType = "application/octet-stream" (or content type of your file).
Response.AppendHeader("content-disposition", "attachment;filename=" & strFileName)

You could create a situation where you can use WebClient if you make your file available through a uri, see this post.

Answer 2

Yes, you can use WebClient. Option is to use HttpRequest and HttpResponse.
