Safe Navigation Operator in C#? [duplicate]

Answer 1

Doesn't exist in C# today, but you can write it with SelectMany.

String lname = from _ in person.Name from s in _.ToUpper() select s;

or

String lname = person.Name.SelectMany(_ => _.ToUpper(), s => s);

(That was Bart De Smet's proposal in his PDC 2010 talk on the future of LINQ. See slide #6.)
