PropertyChanged for indexer property

Question

I have a class with an indexer property, with a string key:

public class IndexerProvider {
    public object this[string key] {
        get
        {

Actually, I believe setting the IndexerName attribute to "Item" is redundant. The IndexerName attribute is specifically designed to rename an index, if you want to give it's collection item a different name. So your code could look something like this:

public class IndexerProvider : INotifyPropertyChanged {

    [IndexerName("myIndexItem")]
    public object this [string key] {
        get {
            return ...;
        }
        set {
            ... = value;
            FirePropertyChanged ("myIndexItem[]");
        }
    }
}

Once you set the indexer name to whatever you want, you can then use it in the FirePropertyChanged event.
