Web application using c# Lab - Web Configuration file
Download as DOC, PDF0 likes179 views
The document describes creating a web configuration file called Web.config for a web application created in C#. The Web.config file contains configuration settings for compilation and runtime, as well as application settings defined for course fees and names. A Course.aspx.cs file uses the configuration settings values from Web.config to display course name and fee labels based on a dropdown selection.
