 virtual bool IsUnrestricted();

public bool IsUnrestricted();

abstract member IsUnrestricted : unit -> bool

true if the DnsPermission instance was created with Unrestricted; otherwise, false.

Implements

IsUnrestricted()

Examples

The following example uses the IsUnrestricted method to check the overall permission state of the object.

public:
   void useDns()
   {
      // Create a DnsPermission instance.
      DnsPermission^ permission = gcnew DnsPermission( PermissionState::Unrestricted );
      // Check for permission.
      permission->Demand();
      Console::WriteLine( "Attributes and Values of DnsPermission instance :" );
      // Print the attributes and values.
      PrintKeysAndValues( permission->ToXml()->Attributes );
      // Check the permission state.
      if ( permission->IsUnrestricted() )
      {
         Console::WriteLine( "Overall permissions : Unrestricted" );
      }
      else
      {
         Console::WriteLine( "Overall permissions : Restricted" );
      }
   }

private:
   void PrintKeysAndValues( Hashtable^ myList )
   {
      // Get the enumerator that can iterate through the hash table.
      IDictionaryEnumerator^ myEnumerator = myList->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 permission = new DnsPermission(PermissionState.Unrestricted);
   // Check for permission.
   permission.Demand();
   Console.WriteLine("Attributes and Values of DnsPermission instance :");
   // Print the attributes and values.
   PrintKeysAndValues(permission.ToXml().Attributes);
   // Check the permission state.
   if (permission.IsUnrestricted())
      Console.WriteLine("Overall permissions : Unrestricted");
   else
      Console.WriteLine("Overall permissions : Restricted");
}

private void PrintKeysAndValues(Hashtable myList) {
   // Get the enumerator that can iterate through the hash table.
   IDictionaryEnumerator myEnumerator = myList.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 permission As New DnsPermission(PermissionState.Unrestricted)
    ' Check for permission.
    permission.Demand()
    Console.WriteLine("Attributes and Values of DnsPermission instance :")
    ' Print the attributes and values.
    PrintKeysAndValues(permission.ToXml().Attributes)
    ' Check the permission state.
    If permission.IsUnrestricted() Then
        Console.WriteLine("Overall permissions : Unrestricted")
    Else
        Console.WriteLine("Overall permissions : Restricted")
    End If
End Sub
 
Private Sub PrintKeysAndValues(myList As Hashtable)
    ' Get the enumerator that can iterate through the hash table.
    Dim myEnumerator As IDictionaryEnumerator = myList.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
