DnsPermission.Copy-Methode

Erstellt eine identische Kopie der aktuellen Berechtigungsinstanz.

Namespace: System.Net
Assembly: System (in system.dll)

Syntax

'Declaration
Public Overrides Function Copy As IPermission
'Usage
Dim instance As DnsPermission
Dim returnValue As IPermission

returnValue = instance.Copy

public override IPermission Copy ()

public:
virtual IPermission^ Copy () override

public IPermission Copy ()

public override function Copy () : IPermission

Rückgabewert

Eine neue Instanz der DnsPermission-Klasse, die eine identische Kopie der aktuellen Instanz ist.

Hinweise

Eine Kopie einer DnsPermission-Instanz ermöglicht denselben Zugriff auf DNS-Server wie die ursprüngliche Berechtigungsinstanz.

Beispiel

Im folgenden Beispiel wird eine identische Kopie einer vorhandenen DnsPermission-Instanz erstellt.

Public Sub UseDns()
    ' Create a DnsPermission instance.
    Dim myPermission As New DnsPermission(PermissionState.Unrestricted)
    ' Check for permission.
    myPermission.Demand()
    ' Create an identical copy of the above DnsPermission object.
    Dim myPermissionCopy As DnsPermission = CType(myPermission.Copy(), DnsPermission)
    Console.WriteLine("Attributes and Values of 'DnsPermission' instance :")
    ' Print the attributes and values.
    PrintKeysAndValues(myPermission.ToXml().Attributes)
    Console.WriteLine("Attribute and values of copied instance :")
    PrintKeysAndValues(myPermissionCopy.ToXml().Attributes)
End Sub 'UseDns


Private Sub PrintKeysAndValues(myHashtable As Hashtable)
    ' Get the enumerator that can iterate through he hash table.
    Dim myEnumerator As IDictionaryEnumerator = myHashtable.GetEnumerator()
    Console.WriteLine(ControlChars.Tab + "-KEY-" + ControlChars.Tab + "-VALUE-")
    While myEnumerator.MoveNext()
        Console.WriteLine(ControlChars.Tab + "{0}:" + ControlChars.Tab + "{1}", myEnumerator.Key, myEnumerator.Value)
    End While
    Console.WriteLine()
