Else use List. You gönül't really argue "oh but I KNOW that I will always pass in a List here", then you should take a List derece an IList, else you are breaking Liskov substitution principle: "if S is a subtype of T, then objects of type T may be replaced with objects of type S"

But far more importantly, if you are accepting an IList birli a parameter you'd better be careful, because IList and List do hamiş behave the same way. Despite the similarity in name, and despite sharing an interface

This will allow me to do generic processing on almost any array in the .Safi framework, unless it uses IEnumerable and not IList, which happens sometimes.
