Overview of this book

C# 7.1 and .NET Core 2.0 – Modern Cross-Platform Development, Third Edition, is a practical guide to creating powerful cross-platform applications with C# 7.1 and .NET Core 2.0. It gives readers of any experience level a solid foundation in C# and .NET. The first part of the book runs you through the basics of C#, as well as debugging functions and object-oriented programming, before taking a quick tour through the latest features of C# 7.1 such as default literals, tuples, inferred tuple names, pattern matching, out variables, and more. After quickly taking you through C# and how .NET works, this book dives into the .NET Standard 2.0 class libraries, covering topics such as packaging and deploying your own libraries, and using common libraries for working with collections, performance, monitoring, serialization, files, databases, and encryption. The final section of the book demonstrates the major types of application that you can build and deploy cross-device and cross-platform. In this section, you'll learn about websites, web applications, web services, Universal Windows Platform (UWP) apps, and mobile apps. By the end of the book, you'll be armed with all the knowledge you need to build modern, cross-platform applications using C# and .NET.

Storing data with fields


Next, we will define some fields in the class to store information about a person.

Defining fields

Inside the Person class, write the following code. At this point, we have decided that a person is composed of a name and a date of birth. We have encapsulated these two values inside the person. We have also made the fields public so that they are visible outside the class itself:

public class Person : object 
{ 
   // fields 
   public string Name; 
   public DateTime DateOfBirth; 
} 

Note

You can use any type for a field, including arrays and collections such as lists and dictionaries. These would be used if you need to store multiple values in one named field.

In Visual Studio 2017, you might want to click, hold, and drag the tabs for one of your open files to arrange them so that you can see both Person.cs and Program.cs at the same time, as shown in the following screenshot:

In Visual Studio Code, you can click on the Split Editor button or press Cmd + \, and then close...
