if property is null then c# code example

Example 1: if property is null then c#

The null-conditional operators are short-circuiting.
That is, if one operation in a chain of conditional member or element 
access operations returns null, the rest of the chain doesn't execute. 
In the following example, B is not evaluated if A evaluates to null 
and C is not evaluated if A or B evaluates to null:
CODE
------------------
A?.B?.Do(C);
A?.B?[C];
