Beispiele

Im folgenden Beispiel wird die Verwendung der IsCollection-Eigenschaft veranschaulicht.

static public void IsElementCollection()
{
    
    // Get the current configuration file.
    System.Configuration.Configuration config =
            ConfigurationManager.OpenExeConfiguration(
            ConfigurationUserLevel.None);
    
    // Get the section.
    UrlsSection section =
        (UrlsSection)config.GetSection("MyUrls");

    // Get the element.
    UrlConfigElement url = section.Simple;

    // Get the collection element.
    UrlsCollection urls = section.Urls;

    bool isCollection =
        url.ElementInformation.IsCollection;
    Console.WriteLine("Url element is a collection? {0}",
        isCollection.ToString());

    isCollection =
       urls.ElementInformation.IsCollection;
    Console.WriteLine("Urls element is a collection? {0}",
        isCollection.ToString());
}

Public Shared Sub IsElementCollection() 
    
    ' Get the current configuration file.
