How to check for nulls in a deep lambda expression? [duplicate]

Answer 1

You can't do that in a concise way. You can either make the lambda multiple lines, or use nested ternary operators:

var result = GetValue(one, x => x.Two == null ? null :
                                x.Two.Three == null ? null :
                                x.Two.Three.Four == null ? null :
                                x.Two.Three.Four.Foo;

Ugly, I know.
