c# - How to sum multiple objects together -

lets have 3 objects

object o1, o2, o3 

these objects have values of

o1 = 1  o2 = 2  o3 = 3 

for simplicity sake

now add these objects sum of 6 + operator cannot used objects. ways can these objects summed without extensively converting them?

the reason using objects rather int etc, due using datatable gets populated sql query. take value datatable , assign o1 example.

you can overload plus operator if make own object type. suspect there other ways this, example:

i take value datatable , assign o1 example.

you assign int @ time. if want use object, because need create more behavior in future, on object type would:q

    // overload operator +     public static yourobject operator +(yourobject a, yourobject b)     {         return new yourobject(a.thevaluepropertyint + b.thevaluepropertyint);     } 

but not going able sum types of c#'s object because not overload + operator.

fundamentally trying use object specific behavior (integer math) without telling compiler want int behaviors.

ultimately, ask if int, or other type. if int, cast extract.
