현재 사용 권한 인스턴스의 동일한 복사본을 만듭니다.

public:
 override System::Security::IPermission ^ Copy();

public override System.Security.IPermission Copy ();

override this.Copy : unit -> System.Security.IPermission

Public Overrides Function Copy () As IPermission

IPermission

현재 인스턴스의 동일한 복사본인 DnsPermission 클래스의 새 인스턴스입니다.

예제

다음 예제에서는 기존 인스턴스의 동일한 복사본을 DnsPermission 만듭니다.

public:
   void UseDns()
   {
      // Create a DnsPermission instance.
      DnsPermission^ myPermission = gcnew DnsPermission( PermissionState::Unrestricted );
      // Check for permission.
      myPermission->Demand();
      // Create an identical copy of the above 'DnsPermission' Object*.
      DnsPermission^ myPermissionCopy = dynamic_cast<DnsPermission^>(myPermission->Copy());
      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 );
   }

private:
   void PrintKeysAndValues( Hashtable^ myHashtable )
   {
      // Get the enumerator that can iterate through the hash table.
      IDictionaryEnumerator^ myEnumerator = myHashtable->GetEnumerator();
      Console::WriteLine( "\t-KEY-\t-VALUE-" );
      while ( myEnumerator->MoveNext() )
      {
         Console::WriteLine( "\t {0}:\t {1}", myEnumerator->Key, myEnumerator->Value );
      }
      Console::WriteLine();
   }

public void UseDns() {
   // Create a DnsPermission instance.
   DnsPermission myPermission = new DnsPermission(PermissionState.Unrestricted);
   // Check for permission.
   myPermission.Demand();
   // Create an identical copy of the above 'DnsPermission' object.
   DnsPermission myPermissionCopy = (DnsPermission)myPermission.Copy();
   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);
}

private void PrintKeysAndValues(Hashtable myHashtable) {
   // Get the enumerator that can iterate through the hash table.
   IDictionaryEnumerator myEnumerator = myHashtable.GetEnumerator();
   Console.WriteLine("\t-KEY-\t-VALUE-");
   while (myEnumerator.MoveNext())
      Console.WriteLine("\t{0}:\t{1}", myEnumerator.Key, myEnumerator.Value);
   Console.WriteLine();
}

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


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()
End Sub

설명

인스턴스의 복사본은 DnsPermission 원래 권한 인스턴스와 동일한 DNS 서버에 대한 액세스를 제공합니다.
