IUnrestrictedPermission.IsUnrestricted

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

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 'useDns

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

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