Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "The preceding code declares two readonly properties with preassigned values."

A block of code is set as follows:

Range book = 1..4;
var res = Books[book] ;
Console.WriteLine($"\tElement of array using Range: Books[{book}] => {Books[book]}");

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

private static readonly int num1=5;
private static readonly int num2=6;

Any command-line input or output is written as follows:

dotnet --info

Bold: Indicates a new term, an important word, or words that you see on screen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Select System info from the Administration panel."
