The previous article learned how to handle the configuration file read, but did not learn about the <appSettings> that is often used, but the reading of these parameters is much simpler:
Suppose you have the following configuration parameters

<appSettings>    <add key= "Address" value= "China"/>  </appSettings>

Read:

String address=system.configuration.configurationmanager.appsettings["Address". ToString ();

The truth is, it's so simple

The above is the C # operation configuration file in the detailed content of App. Config, more relevant content please pay attention to topic.alibabacloud.com (www.php.cn)!
