FileUpload control of ASP. NET 2.0 advanced control

In applications, users are often allowed to upload files to the web server. Although this function can be completed in ASP. NET 1.x, it is easier to use the FileUpload control in ASP. NET 2.0.

This control makes it easier for users to browse and select files for upload. It contains a browse button and a text box for entering file names. If you enter a fully qualified file name in the text box, you can call the SaveAs method of FileUpload to save the file to the disk, whether you enter it directly or click the Browse button.

In addition to the standard members inherited from the WebControl class, the FileUpload control also exposes several read-only attributes listed in tables 5-8 and 5-9.
