A really easy C# question

Does what space things are on effect c#? for example is: using System;

public class hello
{
public static void Main()
{
Console.WriteLine ("Hello C# World ");
}
}

Different from this:
using System;
public class hello {
public static void Main() {
Console.WriteLine ("Hello C# World ");
}
}

Sorry for the silly question I'm completely new to programming.

C# is like C and C++, and doesn't care about whitespace and indentation. (As opposed to python, where spacing is critically important.)

However, it's good practice to put one statement per line, and indent your code consistently (with spaces, for consistency between different viewers and editors).

BTW, for code formatting in questions, select your code and press the little "101" icon in the toolbar to pretty print the code, it makes your question easier to read.
