c# What does this line mean?
c#, null-coalescing-operator, return-value
Solution
Yes, that's what it means. It's called the null-coalescing operator.
It's just a syntax shortcut. However, it can be more efficient because the value being read is only evaluated once. (Note that there can also be a functional difference in cases where evaluating the value twice has side effects.)
Problem
Could anybody explain the following code `return total ?? decimal.Zero` please? ``` public decimal GetTotal() { // Part Price * Count of parts sum all totals to get basket total decimal? total = (from basketItems in db.Baskets where basketItems.BasketId == ShoppingBasketId select (int?)basketItems.Qty * basketItems.Part.Price).Sum(); return total ?? decimal.Zero; } ``` Does it mean the following? ``` if (total !=null) return total; else return 0; ```
