LINQ - FirstOrDefault() then Select()

I have the following LINQ query that fires an exception when the FirstOrDefault() returns null. Ideally I would like to avoid the null check. Is there a way to do this? I wish to return 0 if there are no CPOffsets that satisfy the FirstOrDefault() call.

double offset = OrderedOffsets.FirstOrDefault(o => o.OffsetDateTime > cpTime).CPOffset;

The only way I can see to achieve this is the following:

CPOffset cpOffset = OrderedOffsets.FirstOrDefault(o => o.OffsetDateTime > cpTime);
double offset = cpOffset != null ? cpOffset.CPOffset : 0;

Is there another more succinct way? Using Select() after the FirstOrDefault() doesn't compile but I thought might be appropriate here?

Solution

  • I think this should work, I'm not near by VS to check it out... 

    OrderedOffsets.Where(o => o.OffsetDateTime > cpTime).Select(x => x.CPOffset).FirstOrDefault();
