Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text are shown as follows: "The Iterator method returns IEnumerable that results in three DateTime values."

A block of code is set as follows:

public static IEnumerable<DateTime> Iterator()
{
Thread.Sleep(1000);
yield return DateTime.Now;
Thread.Sleep(1000);
yield return DateTime.Now;
Thread.Sleep(1000);
yield return DateTime.Now;
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

namespace ConsoleApplication
{

using Numerical;
internal class Program
{
private static void Main(string[] args)
{
var values = new int[] {1, 2, 3};
foreach (var v in values.Cubes())
{
Console.WriteLine(v);
}
}
}
}

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "right-click on a project in Solution Explorer and select Unload Project."
