ConfigurationElement.IsReadOnly Metoda

Definicja

Pobiera wartość wskazującą, czy ConfigurationElement obiekt jest tylko do odczytu.Gets a value indicating whether the ConfigurationElement object is read-only.

public:
 virtual bool IsReadOnly();
public virtual bool IsReadOnly ();
abstract member IsReadOnly : unit -> bool
override this.IsReadOnly : unit -> bool
Public Overridable Function IsReadOnly () As Boolean

Zwraca

true, jeśli obiekt ConfigurationElement jest tylko do odczytu; w przeciwnym razie false.true if the ConfigurationElement object is read-only; otherwise, false.

Przykłady

Poniższy przykład pokazuje, jak używać metody IsReadOnly.The following example shows how to use the IsReadOnly method. Jest on używany w sekcji niestandardowej i zwraca false.It is used on a custom section and returns false.

// Show how to use IsReadOnly.
// It loops to see if the elements are read only. 
static void ReadOnlyElements()
{
    try
    {
        // Get the configuration file.
        System.Configuration.Configuration config =
            ConfigurationManager.OpenExeConfiguration(
            ConfigurationUserLevel.None);

        // Get the MyUrls section.
        UrlsSection myUrlsSection =
            config.GetSection("MyUrls") as UrlsSection;

        UrlsCollection elements = myUrlsSection.Urls;

        IEnumerator elemEnum =
            elements.GetEnumerator();

        int i = 0;
        Console.WriteLine(elements.Count.ToString());

        while (elemEnum.MoveNext())
        {
            Console.WriteLine("The element {0} is read only: {1}",
             elements[i].Name,
             elements[i].IsReadOnly().ToString());
            i += 1;
        }
    }
    catch (ConfigurationErrorsException err)
    {
        Console.WriteLine("[ReadOnlyElements: {0}]",
            err.ToString());
    }
}
' Show how to use IsReadOnly.
' It loops to see if the elements are read only. 
Shared Sub ReadOnlyElements()
    Try
        ' Get the current configuration file.
        Dim config _
        As System.Configuration.Configuration = _
        ConfigurationManager.OpenExeConfiguration( _
        ConfigurationUserLevel.None)

        ' Get the MyUrls section.
        Dim myUrlsSection As UrlsSection = _
        config.GetSection("MyUrls")

        Dim elements As UrlsCollection = _
        myUrlsSection.Urls

        Dim elemEnum As IEnumerator = _
        elements.GetEnumerator()

        Dim i As Integer = 0
        Console.WriteLine(elements.Count.ToString())

        While elemEnum.MoveNext()
            Console.WriteLine("The element {0} is read only: {1}", _
            elements(i).Name, elements(i).IsReadOnly().ToString())
            i += 1
        End While
    Catch err As ConfigurationErrorsException
        Console.WriteLine("[ReadOnlyElements: {0}]", _
        err.ToString())
    End Try

End Sub

Uwagi

System definiuje elementy konfiguracji, których nie można modyfikować.The system defines configuration elements that cannot be modified.

Aby określić, które elementy mogą być modyfikowane, użyj metody IsReadOnly.To determine which elements can be modified, use the IsReadOnly method.
