C# 4: how to in-line detect for nulls?

Question

In C# 4, wasn't there a short cut for checking for null values like so:

if( myobject?.myproperty?.myotherproperty?.value != null )

The value would return null and not throw an exception.

Anyone have a link to how to use it or at least the syntax?

Answer 1

This operator is called the safe navigation operator in Groovy.

It is not available in C# yet, not even in C# 4.

If enough people show their support for it, maybe it will get into a hypothetical future version of C#...

Answer 2

Nope, sorry, no such thing. They did consider it, but it didn't make the cut.

Answer 3

In C# there's also ?? operator that is used for testing against null. This is slightly better than ? operator.

(x ?? -1) is equivalent to (x!= null ? x: -1)
