ASP.NET provides an easy mechanism to upload files from a Web Browser to a Web Server. The class HtmlInputFile allows to handle programmatically the information submitted by the INPUT control of the type file, e.g., < input type"file" >. Remember that the Input control of type file is only available in Web Browsers that support HMTL 3.2 and later versions. This HTML version is supported by IE 3.02 and Netscape 3.0 and their later versions.
