Question

it’s kind a simple question but i have the doubt see the code belows

public static String something;
    static void Main(string[] args)
    {
        try
        {
            if (something == "blah")
                System.Console.Write("ok");
        }
        catch (Exception)
        {

            throw;
        }

    }

i know that doesn’t throw an exception but why? because the variable with the name something it’s null and when you compare you’re trying to get a reference with null. Can someone please explain to me why? Thanks!

Answer 1

The variable, something, doesn’t need to be instanced for that kind of comparison. It knows how to compare itself to a null.

So it doesn’t throw an exception because

null == “string”

is a valid comparison which returns false.
