Örnekler

Aşağıdaki örnek, ek appSettings değerleri bir dış yapılandırma dosyasında depolar ve bu dosyanın adını özelliğine File kaydeder.

// This function shows how to use the File property of the
// appSettings section.

// configuration file.
// Usually you create an auxiliary file off-line to store 
// additional settings that you can modify as needed without
// causing an application restart,as in the case of a Web 
// application.
// These settings are then added to the ones defined in the
// application configuration file.
