FirstOrDefault inline null checking

Question

I have following code :

var result = new Collection<object>();

result.Add(
     list.Select(s => new
     {
          s.Name,
          Rating = s.Performance.OrderByDescending(o => o.Year).FirstOrDefault().Rating
     })
);

If there's no record found in Performance, it will give me NullException which is expected because I'm trying to get Rating property from null value so my question is how to set null if FirstOrDefault() is null and get Rating value if not.

Thanks

Answer 1

Do this:

Rating = s.Performance.OrderByDescending(o => o.Year)
                      .Select(o => o.Rating)
                      .FirstOrDefault()
