Question

I have a custom class in F# and I want to implement the [] list operator such that

let myClass = new myClassObj()
let someVal  = myClass.[2]

I can’t seem to find this on the web – I probably don’t know the right term to search for… thanks in advance

You just need to implement an Item indexed property. E.g.

type MyClass() =
  member x.Item with get(i:int) = (* some logic involving i here *)
