How can I make a read-only ObservableCollection property?
- by thrag
I'd like to expose a property on a view model that contains a list of objects (from database).
I need this collection to be read-only. That is, I want to prevent Add/Remove, etc. But allow the foreach and indexers to work. My intent is to declare a private field holding the editable collection and reference it with a read-only Public Property. As follows
public ObservableCollection<foo> CollectionOfFoo {
get {
return _CollectionOfFoo;
}
}
However, that syntax just prevents changing the reference to the collection. It doesn't prevent add/remove, etc.
What is the right way to accomplish this?
