When you typed y.ToString square braces appeared at the end [ ] but that doesnt work for me, it does work however if I use the curved braces ( ), I don't understand why

I was also JUST watching the video and I watched the same thing and was about to comment on it. Really cool but can you please explain the () at the end and how, if we had not seen it we would have known to put the () at the end of the line.

It's part of the syntax of C# but you really didn't need to know that because when you put the . after y the intellisense auto-completion added the () to the end after you selected .ToString().  Visual Studio would have told you that this was a problem as well.  I think it even goes so far as to tell you that it expects parentheses.

int firstInt = foo[0]; // returns first
int fifthInt = foo[4]; // returns 5th in array

Now () is typically for methods and constructors.  so if I have an a string, I'd go

string myString = new string();

If I have an integer and wanted to change it into a string, I have to cast it.  Since .ToString is a method, I have to do use () since some methods allow you to pass stuff in.  With (), I'm passing in nothing.

int five = 5;
string theNumberFive = five.ToString();
