Checking if an object is null in C#

Question

I would like to prevent further processing on an object if it is null.

In the following code I check if the object is null by either:

if (!data.Equal         


        

Answer 1

As of C# 9 you can do

if (obj is null) { ... }

For not null use

if (obj is not null) { ... }

If you need to override this behaviour use == and != accordingly.
