Conventions used

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

Code in text: 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 enum data type is 4 bytes (32 bits) in size, nullable, and has a minimum value of 0. You can measure the size of a value type using sizeof(Type type).”

A block of code is set as follows:

static void Main(string[] _) 

{ 

Console.WriteLine(“Chapter 3: Strings are immutable”); 

var greeting1 = “Hello, world!”; 

var greeting2 = greeting1; 

Console.WriteLine($”greeting1={greeting1}”); 

Console.WriteLine($”greeting2={greeting2}”); 

greeting1 += “ Isn’t life grand!”; 

Console.WriteLine($”greeting1={greeting1}”); 

Console.WriteLine($”greeting1={greeting2}”); 

} 

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

git clone https://github.com/dotnet/roslyn.git

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

csc /help
csc -langversion:10.0 /out:HelloWorld.exe Program.cs
csc HelloWorld
cd css

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Make sure the project is set to Debug mode, and then step through the code.”
