I was reading through some code over the weekend and came across a null-coalescing operator. So I thought I would write a blog post about it and the ternary operator.
null-coalescing operator (??)
x = y ?? z
If y is null, then z is assigned to x, otherwise y will be assigned to x
ternary operator (?:)
a = (b < c) ? b : c
if the condition (b < c) is true b will be returned, if the condition is not true c will be returned.
Remarks:
Personally, I might use the null-coalescing operator however I think in most instances I would stay away from both operators. Mainly from a code readability and maintainability perspective.
