Expression bodied member extended
Expression bodied members were introduced in C# 6.0 where the syntactical expression of the method can be written in a simpler way. In C# 7.0, we can use this feature with a constructor, a destructor, an exception, and so on.
The following example shows how the constructor and destructor syntactic expressions can be simplified using expression bodied members:
public class PersonManager { //Member Variable Person _person; //Constructor PersonManager(Person person) => _person = person; //Destructor ~PersonManager() => _person = null; }
With properties, we can also simplify the syntactic expression, and the following is a basic example of how this can be written:
private String _name; public String Name { get => _name; set => _name = value; }
We can also use an expression bodied syntactic expression with exceptions and simplify the expression, which is shown as follows:
private String _name; public String Name { get => _name; set => _name = value ?? throw new ArgumentNullException(); }
In the preceding example, if the value is null, a new ArgumentNullException will be thrown.
