I'm developing an ASPNET Core WebAPI application. I will have a base model and potentially have many, many derived types of the base model. I do not want to create specialized endpoints for each of these derived types. What I would like to do is have my controller deserialize an incoming object into the base type, pass it to the service layer at which point I can determine which derived type it is and then handle it.
For example, my models might look something like this:
public class ModelA
{
public string PropA1 { get; set; }
public int PropA2 { get; set; }
}
public class ModelB : ModelA
{
public string PropB1 { get; set; }
public int PropB2 { get; set; }
}
public class ModelC : ModelA
{
public string PropC1 { get; set; }
public int PropC2 { get; set; }
}
Controller would be this:
[Route("api/[controller]")]
public class MyController : Controller
{
[HttpPut]
public void Put(ModelA model)
{
// model could be B or C (but never A).
}
}
Where the "model" parameter could actually be ModelC or ModelB (or, in reality, many many others, but never the base class). I will then pass the model to a service provider which will then determine the derived type and handle it appropriately.
In addition, each of the derived types could have validation attributes (and/or implement IValidatableObject). Preferably, I would like the framework to be able to handle validation of the derived type.
Is this possible?
