The problem is that topAgents
is dynamic
– so your ToList()
call is dynamic, and so is Select
. That has issues that:
- you can’t use lambda expressions for dynamic calls like this;
- dynamic calls don’t find extension methods anyway.
Fortunately, the operations don’t need to be dynamic just because the element type is dynamic. You could use:
IEnumerable<dynamic> topAgents = ...;
… or just use var
. Both of those should be fine.
