Some data needs to be written to the configuration file. We should try to write it into the configuration file. For example, you can change the frequently changed data or change the configuration file to use a value, such as an IP address. Port Number, MD5 and salt. And so on. We can write these values into the web. config file. You can obtain this value on the webForm. aspx. cs page or other pages.

Note that the configuration is performed in the <etettings> </appSettings> file.
