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

Because Count method always returns integer if no elements in array it will return 0 other wise it will return number of elements. So what you need to do is just instead != null make it != 0 or > 0
