MongoDB C# Linq driver with nullable types

Question

I am using mongodb c# driver and tried the following query

collection.AsQueryable().Where(x => x.IsArchived.GetValueOrDefault())

where IsArchived is of type bool? (nullable).

I get the following runtime error:

Unsupported where clause: x.IsArchived.GetValueOrDefault().

Does anybody know how I can query nullable types?

Answer 1

i found out a workaround, though it is not very nice:

collection.AsQueryable().Where(x => x.IsArchived ?? false)
