예제

다음 예제에서는 IsPresent 속성을 사용하는 방법을 보여 줍니다.The following example shows how to use the IsPresent property.

static public void IsElementPresent()
{
    // 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;

    bool isPresent =
        url.ElementInformation.IsPresent;
    Console.WriteLine("Url element is present? {0}",
        isPresent.ToString());
}
Public Shared Sub IsElementPresent() 

    ' Get the current configuration file.
    Dim config _
    As System.Configuration.Configuration = _
    ConfigurationManager.OpenExeConfiguration( _
    ConfigurationUserLevel.None)

    ' Get the section.
    Dim section As UrlsSection = _
    CType(config.GetSection("MyUrls"), UrlsSection)
    
    ' Get the element.
    Dim url As UrlConfigElement = _
    section.Simple
    
    Dim isPresent As Boolean = _
    url.ElementInformation.IsPresent
    Console.WriteLine("Url element is present? {0}", _
    isPresent.ToString())

End Sub
