Zusätzlich zur Verwendung der Methode der Vererbung von IConfigurationSectionHandler zum Definieren einer Klasse für die Verarbeitung benutzerdefinierter Knoten können Sie den gleichen Effekt auch durch die Vererbung der ConfigurationSection-Klasse erzielen.
Lassen Sie uns zunächst über eine unausgesprochene Regel in der .Net-Konfigurationsdatei sprechen
Bei der Konfiguration eines Knotens für die Parameter, die Sie speichern möchten. Daten können auf zwei Arten gespeichert werden: Eine wird in den Attributen des Knotens gespeichert, die andere wird im Text des Knotens gespeichert.
Da ein Knoten viele Attribute haben kann, aber nur ein innererText, im hinzugefügt werden muss Programm Die Unterscheidung dieser beiden Formen führt zu Komplikationen. Um dieses Problem zu vermeiden, wird die Konfigurationsdatei von .net nur mit Attributen gespeichert, anstatt innertext.
Als nächstes schreiben wir eine benutzerdefinierte Konfigurationsdatei, die dieser unausgesprochenen Regel entspricht, um das Testen zu erleichtern:
<mailServerGroup provider="www.baidu.com">
<mailServers>
<mailServer client="http://blog.csdn.net/lhc1105" address="13232@qq.com" userName="lhc" password="2343254"/>
<mailServer client="http://blog345.csdn.net/lhc1105" address="132wdfgdsggtaewg32@qq.com" userName="dfshs水田如雅" password="2334t243的萨芬234254"/>
<mailServer client="http://blog436.csdn.net/lhc1105" address="132wdgadsfgdtaewg32@qq.com" userName="sdfhdfs水田如雅" password="23ewrty2343的萨芬234254"/>
<mailServer client="http://blo345734g.csdn.net/lhc1105" address="132wdgdfagdstaewg32@qq.com" userName="sdfher水田如雅" password="23erwt43的萨芬234254"/>
</mailServers>
</mailServerGroup>Als nächstes schreiben wir die entsprechende Verarbeitungsklasse, hier schreiben wir von innen nach außen:
Zuerst ist der innerste MailServer:

}Ebenso die Assoziationsverarbeitungsklasse und Knoten:

Führen Sie dann einen Test durch:

{

Console.WriteLine("MailServerSection 的provider属性值："+mailSection.provider);
foreach (MailServerElement config in mailSection.MailServers)
{
Console.WriteLine("----------------------------------");
Console.WriteLine("client值为："+config.Client);
Console.WriteLine("address值为："+config.Address);
Console.WriteLine("username值为："+config.UserName);
Console.WriteLine("password值为："+config.Password);
Console.WriteLine("----------------------------------");
}
Console.ReadKey();
}
} Ursprünglich wollte ich ein Bild der Ergebnisse hochladen, aber die Internetgeschwindigkeit ist langsam, vergessen Sie es, ich werde die Ergebnisse selbst ausführen, wenn ich gerne spiele. . . . .
