Why am I getting “CS0472: The result of the expression is always true since a value of type int is never equal to null of type int?”

Question

string[] arrTopics = {\"Health\", \"Science\", \"Politics\"};

I have an if statement like:

 if (arrTopics.Count() != null)
<         


        

Answer 1

int can never be equal to null. int? is the nullable version, which can be equal to null.

You should check if(arrTopics.Count() != 0) instead.
