Edit: The main purpose of this question is to gain a deeper understanding of C# and OOP in general. Please keep in mind that I'm not trying to solve a specific problem with this code, but instead just trying to understand how everything works.
I have a way to do this, but I'm wondering if there is another way to do it.
public abstract class ModelBase
{
private const string ERROR = "Error";
public string Status { get; set; }
public string StatusDescription { get; set; }
public static T Error<T>(string errorDescription)
where T : ModelBase, new()
{
var model = new T
{
Status = ERROR,
StatusDescription = errorDescription
};
return model;
}
}
And then to call it:
return ModelBase.Error<ApplicationInit>("Failed to retrieve application segment.");
Where "ApplicationInit" is a derived class of ModelBase.
What would be super cool is if instead, I could call:
return ApplicationInit.Error("Failed to retrieve application segment.");
...And the code would be able to just tell what the derived class is.
IDK, maybe that's not possible...
No. When you declare a static
method, there is only one version* of it. The call ModelBase.Error<ApplicationInit>("")
and the call ApplicationInit.Error<ApplicationInit>("")
will both compile to the exact same bytecode, and a good set of analyzers will flag the latter with a warning.
You can shadow Error
with a new static method in ApplicationInit
, but that would be a manual process for each new subclass. There is no way^ to generalize it more than you already have.
* A generic method can produce different bytecode for different type parameters, but all such methods are static members of ModelBase
, and not any subclass.
^ You could write a source generator to generate these static methods, but that is a lot more work than just using the generic ModelBase.Error<T>
method directly.
