Question

See the below code

   totLen = (r.Field<int>("Quantity") <= 0 ? 1 : r.Field<int>("Quantity")) *
   ((r.Field<decimal>("Breath") <= 0 ? 1 : r.Field<decimal>("Breath")) * 
   (r.Field<decimal>("Length") <= 0 ? 1 : r.Field<decimal>("Length")) * 
   (r.Field<decimal>("Height") <= 0 ? r.Field<decimal>("Height") : r.Field<decimal>("Height")))

In this code I had think that if any value of the r.Field(COLUMN NAME) come zero than it should be replaced by 1 only for multiplication by using ? and : conditional operator but its gives me wrong output and return a ZERO(0)…
Can Any one suggest me why this happening?

Answer 1

If the “Height” field is 0 you’re still using it in your multiplication.

Change

r.Field<decimal>("Height") <= 0 ? r.Field<decimal>("Height") : r.Field<decimal>("Height")

to

r.Field<decimal>("Height") <= 0 ? 1 : r.Field<decimal>("Height")
