C# 10 and .NET 6 – Modern Cross-Platform Development - Sixth Edition

Overview of this book

Extensively revised to accommodate all the latest features that come with C# 10 and .NET 6, this latest edition of our comprehensive guide will get you coding in C# with confidence. You’ll learn object-oriented programming, writing, testing, and debugging functions, implementing interfaces, and inheriting classes. The book covers the .NET APIs for performing tasks like managing and querying data, monitoring and improving performance, and working with the filesystem, async streams, and serialization. You’ll build and deploy cross-platform apps, such as websites and services using ASP.NET Core. Instead of distracting you with unnecessary application code, the first twelve chapters will teach you about C# language constructs and many of the .NET libraries through simple console applications. In later chapters, having mastered the basics, you’ll then build practical applications and services using ASP.NET Core, the Model-View-Controller (MVC) pattern, and Blazor.

Controlling access with properties and indexers

Earlier, you created a method named GetOrigin that returned a string containing the name and origin of the person. Languages such as Java do this a lot. C# has a better way: properties.

A property is simply a method (or a pair of methods) that acts and looks like a field when you want to get or set a value, thereby simplifying the syntax.

Defining read-only properties

A readonly property only has a get implementation.

  1. In PersonAutoGen.cs, in the Person class, add statements to define three properties:
    1. The first property will perform the same role as the GetOrigin method using the property syntax that works with all versions of C# (although, it uses the string interpolation syntax from C# 6 and later).
    2. The second property will return a greeting message using the lambda expression body => syntax from C# 6 and later.
    3. The third property will calculate the person's age.
