Setting and Retrieving Custom Application Settings

The final configuration element is a special one because it allows you to configure your own custom application settings, which can then be easily retrieved from within your ASP.NET applications.

<appSettings>

The <appSettings> element allows you to create your own configuration settings as key/value pairs. You can use this configuration element to store configuration information such as DSNs for data access, and then retrieve them in your application using the following syntax:

string DSN DSN = ConfigurationSettings.AppSettings["dsn "];

This is assuming that youve stored the DSN using dsn as the key.

The <appSettings> element has the following syntax:

<appSettings> <ad key="string value="string" /> <clear /> <remov key="string" /> </appSettings>

Table B-20 describes the <appSettings> element attributes in more detail.
