Title Body

In C# I find indexed properties extremely useful. For example: var myObj = new MyClass(); myObj[42] = "hello"; Console.WriteLine(myObj[42]); However as far as I know there is no syntactic sugar to support fields that themselves support indexing (please correct me if I am wrong). For example: var myObj = new MyClass(); myObj.field[42] = "hello"; Console.WriteLine(myObj.field[42]); The reason I need this is that I am already using the index property on my class, but I have GetNumX() , GetX() , and SetX() functions as follows: public int NumTargetSlots { get { return _Maker.NumRefs; } } public ReferenceTarget GetTarget(int n) { return ReferenceTarget.Create(_Maker.GetReference(n)); } public void SetTarget(int n, ReferenceTarget rt) { _Maker.ReplaceReference(n, rt._Target, true); } As you can probably see exposing these as one indexable field property would make more sense. I could write a custom class to achieve this every time I want the syntactic sugar but all of the boilerplate code just seem unnecessary. So I wrote a custom class to encapsulate the boilerplate and to make it easy to create properties that can be indexed . This way I can add a new property as follows: public IndexedProperty<ReferenceTarget> TargetArray { get { return new IndexedProperty<int, ReferenceTarget>( (int n) => GetTarget(n), (int n, ReferenceTarget rt) => SetTarget(n, rt)); } } The code for this new IndexedProperty class looks like: public class IndexedProperty<IndexT, ValueT> { Action<IndexT, ValueT> setAction; Func<IndexT, ValueT> getFunc; public IndexedProperty(Func<IndexT, ValueT>
