Obviously, you can, and this is where we use dependency injection, or factory. suppose you have 2 classes public class ClassA { // some properties and Method //Get(){}; } public class ClassB { //some properties and method // Get(){}; } then declare an Interface for Interface for them public interface IWrapper { // same number of methods with same signature //Get(); } Now, your classes must inherit from the interface public class ClassA :IWrapper { // some properties and method implementaion //Get(){}; } public class ClassB: IWrapper { //Get(){}; //some properties and method implementations } Register dependency on the unity container or create a factory class to resolve it var container = new UnityContainer(); container.RegisterType (); Note:- install Unity from NuGet to get the config. now, use interface, instead of concrete class and change the dependency at run time public class Controller: Controller { private IWrapper _wp; public Controller(IWrapper wp) { _wp=wp; } var res=_wp.Get(); } // The Unity /factory will resolve this dependency at run time
