    1. Use brackets when you want to create an array, like this is a string array "string[]" and use parentheses to call a method.
    2. typeof() get's a instance of a Type class when you pass it a class type, like typeof(string) is the same as StringInstance.GetType().
    3. No difference. They are alliases. lowercase is a keyword resolved at compile time.
    Cheers,
