Das folgende Beispiel zeigt einen Konfigurations Auszug, der im vorherigen Beispiel verwendet wurde.The following example is a configuration excerpt used by the previous example.

<?xml version="1.0" encoding="utf-8"?>  
<configuration>  
  <configSections>  
    <section name="CustomSection" type="Samples.AspNet.CustomSection,   
      ConfigurationErrorsException, Version=1.0.0.0, Culture=neutral,   
      PublicKeyToken=null" allowDefinition="Everywhere"   
      allowExeDefinition="MachineToApplication"   
      restartOnExternalChanges="true" />  
  </configSections>  
  <CustomSection fileName="default.txt" maxUsers="10" />  
</configuration>  

Hinweise

Die ConfigurationErrorsException -Ausnahme wird ausgelöst, wenn beim Lesen oder Schreiben von Konfigurationsinformationen ein Fehler auftritt.The ConfigurationErrorsException exception is thrown when any error occurs while configuration information is being read or written.
