There are no such devices in C#. A few options are available, though:
- in C# 4.0 and .NET 4.0 (or above), use
dynamic
, which supports+
but offers no compile time checking - in .NET 3.5 (or above), MiscUtil offers an
Operator
class which makes operators available as methods – again, without any compile-time checking
So either:
return (dynamic)left.Evaluate(context) + (dynamic)right.Evaluate(context);
or
return Operator.Add(left.Evaluate(context), right.Evaluate(context));
