C# Basic program not compiling wtf?

[~OddBall~]

I have endeavoured to start learning C# for real this time, I am thoroughly reading and going through Wrox.Professonal.C.Sharp.2008 and so far have learnt a lot, mainly about .NET after just reading the first chapter.

Currently on chapter #2 and have just learnt about variables (nothing new there) and am now onto scopes. I 100% understand what it's trying to tell me, however I have promised myself I will do all the code examples, actually type them out so I learn from typing it.

This current example is showing how you can have two variables with the same name (in this case "j") as long as they aren't declared in the same method (Or something like that). Anyways here is the code below:

using System;

namespace Wrox.ProCSharp.Basics
{
	class ScopeTest
	{
		static int j = 20;
		Console.WriteLine(j); //Line 8!!!
		
		public static void Main()
		{
			int j = 30;
			Console.WriteLine(j);
			Console.WriteLine(ScopeTest.j);
			Console.ReadLine();
			return;
		}
	}
}

Now I've copied that completely from the book, checked it line for line and it's correct but the code does not compile.

Error(8,20): error CS1519: Invalid Token '(' in class, struct, or interface member declaration

Error(8,22): error CS1519: Invalid Token ')' in class, struct, or interface member declaration

Line 8 has been bolded, I've looked at it and really cannot see what I'm doing wrong, ideas anyone?

[Mr.Zunz]

Place line 8 in the inside of a method / function

You can define variables outside methods / function, the rest you need to do inside a method / function,

So basicly you can remove line 8 because you already have to same line inside the
public static void Main()

Interesting, must be a mistake in the book. Thank you xD

What for a stupid book is that then
it's wrox, yea? you are really sure that you didn't make that mistake?

It's not a mistake. The point is that you are able to use the same name on variables without them touching each other.

100%, but there's over 1000 pages, I'll forgive them for making one mistake.

and ye Danne it is a mistake, because you can't execute that line outside a method. Don't know why I didn't realise that but then again I haven't done this shit in like two years.

Nope, you wont execute it. The point is still that you can use the same name on two variables, and that they're independent of each other.

But it doesn't compile, hence it's a mistake O_o
