Summary of using relative paths in ASP. NET

If the path of an image on a website is http: // localhost: 2008/websit1/images/1.jpg

Websit1 indicates a virtual path or site

In asp.net, if we enter Response. Write (Request. MapPath ("/01.jpg") on the. cs page "));

This can output the physical path of the image, that is, the specific path of the image stored on the server.
