ASP.NET in a Nutshell

HttpPostedFile

Synopsis

The HttpPostedFile class allows you to easily manipulate files that are uploaded by the client. An HttpPostedFile instance is provided by the PostedFile property of the System.Web.UI.HtmlControls.HtmlInputFile control.

You can use the SaveAs() method to save a posted file to disk synchronously. The method will return once the file is completely uploaded. Alternatively, you can get a System.IO.Stream object containing the file from the InputStream property and use it to work with the file asynchronously (while it is being uploaded).
