LINQ Max() with Nulls

Question

I have a list that contains a bunch of Points (with an X and Y component).

I want to get the Max X for all points in the list, like this:

double max          


        

Answer 1

Place a nullable cast INSIDE the expression to ensure that a blank list will cast as a null. You can then add defaults.

double max = pointList.Max(p=>(double?)p.X) ?? 0;
