FileDialog in WEB forms application

[Rostrox]

I have a WEB form associated to a C#. One of my issues is to show a file Dialog for choosing a file and process it. How can I get this using a Web Development? In Windows forms it is clear.

Use the <input type="file"> tag in your ASPX page (or other HTML file). Then read the .NET SDK Documentation about HttpRequest.Files. That gives you a collection of HttpPostedFile objects that you can save to disk. It's a nice little wrapper but isn't necessary if you don't want to use it. All form data is passed as "multipart/form-data" so it's just a matter of handling multiple segments in a MIME document. I'd recommend the wrapper classes, though - they make it much easier.
