Check for null in foreach loop

Question

Is there a nicer way of doing the following:
I need a check for null to happen on file.Headers before proceeding with the loop

if (file.Headers != null         


        

Answer 1

Using Null-conditional Operator and ForEach() which works faster than standard foreach loop.
You have to cast the collection to List though.

   listOfItems?.ForEach(item => // ... );
