Change Object Type at runtime c#

Obviously, you can, and this is where we use dependency injection, or factory.

suppose you have 2 classes

then declare an Interface for Interface for them

Now, your classes must inherit from the interface

Note:- install Unity from NuGet to get the config.

now, use interface, instead of concrete class and change the dependency at run time

HI
You can use dynamic variable and do conversion as shown
public dynamic output { get; set; }
Based on values, you can do conversion in any model/object

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
