Unity Constructor Injection code example

Unity Constructor Injection code example

If you instantiate a class with Unity and the constructor of that class relies on one or more other classes, Unity automatically creates an instance of the dependent class specified in the parameter for the constructor.
For example, the following code shows a class named "CustomerService" whose constructor's arguments depend on a class named "Loggingservice".

public class customerservice{public  customerservice (loggingservice log)  {     log. WriteToLog ("I ' m an injected concrete logging service.");  

At run time, you can use the Resolve method of the Unity container to create an instance of the "CustomerService" class, and a concrete implementation of a "Loggingservice" class is injected into the "customerservice" instance.

Iunitycontainer container = new UnityContainer (); CustomerService customer = container. Resolve<customerservice> ();
