Handling null values : A better approach

Better way to handle null values in c#

Lets say we receive some value and it is null and we are going to use that in our code

var getValue = null;  
var result = getValue / 2;

Above code will throw a null exception.

To avoid that one might add a condition that could be:

if (getValue != null)  
{  
var result=getValue / 2;  
}

A better way could be like below:

var result= (getValue ?? 0) / 2;
