This is a silly question, but you can use this code to check if something is a particular type…
if (child is IContainer) { //....
Is there a more elegant way to check for the “NOT” instance?
if (!(child is IContainer)) { //A little ugly... silly, yes I know...
//these don't work :)
if (child !is IContainer) {
if (child isnt IContainer) {
if (child aint IContainer) {
if (child isnotafreaking IContainer) {
Yes, yes… silly question….
Because there is some question on what the code looks like, it’s just a simple return at the start of a method.
public void Update(DocumentPart part) {
part.Update();
if (!(DocumentPart is IContainer)) { return; }
foreach(DocumentPart child in ((IContainer)part).Children) {
//...etc...
