try/catchis definitely slower, since a thrown exception causes stack information to be gathered.as/isare for comparing to a type known at compile time and cater for inheritance (ie."string" is Objectreturnstrue)typeof/GetType()can be used for types known at runtime but do not cater for inheritance (ie."string".GetType() == typeof(Object)returnsfalse)Regardless, I think you probably want
as(orisif you don’t need the cast value)
