Well, "string" is actually an object type of the System.String class. So if you omit "using System" from your program, this will not compile:


Whereas this line of code would compile whether or not "using System" is in your code or not.

Think of string as a "shortcut" to the System.String class whereas String is basically directly making a variable of type System.String when "using System" is in the program.

(string == System.String)

Thanks for replying.
So basically, I can use either or as long as I pay attention to whether using System. Using System is automatically added into new projects. I wonder, when would you not using System?
There's no advantage then of using String over string or is there?

There is no advantage. string == System.String.
