Using C# 6 new features

In this recipe, we will discover some of the new features in C# 6.

How to do it...

1. Feature one—auto initializer for properties:

Before C# 6, we should initialize a property with a value in the class constructor. There is no point in time before the class constructor, so we should use it. Thanks to C# 6 syntax, we can now initialize a property with a value right on the declaration line. No need to use constructor anymore:

• • Before:

public class Person
{
 Public class Name {get;set;}
 Public Person(){
 Name = "Stephane";
 }
}

• • Now:

Public string Name {get;set;} = "Stephane";

2. Feature two—auto initializer for static properties:

Auto initializers can be applied to static properties, as well:

• • Before:

Public static string Name {get;set;}

• • Now:

Public static string Name {get;set;} = "Stephane";

3. Feature three—read-only properties:

Auto initializers can even be applied to read-only properties:

• • Before:

public List SocialNetworks { get; }

• • Now:

public List SocialNetworks { get; } =
new List { "Twitter...
