继承和通用类型

Question

I have a generic model that implements a static method. Ideally I would like to avoid having to implement the method in the class that inherits the generic class. But I can't see how I can avoid setting the type.

It would be cool if I could get the type directly in the generic model...

Any suggestions?

abstract public class GenericFactory
    {
        public async Task<T> FindByUuid<T>(Guid uuid) where T:GenericModel, new()
        {
            return await rest.HttpGet<T>($"https://.../{uuid.ToString()}");
        }
    }

public class Contracts : GenericFactory
    {
        public async Task<Contract> FindByUuid(Guid uuid)
        {
            return await base.FindByUuid<Contract>(uuid);
        }
    }

EDIT: Sorry, my example was wrong. I removed and changed some things around to make my point clear. Instead I did the opposite. I've edited the code example to reflect this.

I assume you want your derived class Contract to only allow instances of Contract within your FindByUuid -method. Doing so won´t need to override the base-method, you just have to set the generic type-parameter to your class instead of the method itself:

public class GenericFactory<T> where T : GenericModel, new()
{
    public async Task<T> FindByUuid<T>(Guid uuid) 
    {
        return await rest.HttpGet<T>($"https://.../{uuid.ToString()}");
    }
}

public class Contracts : GenericFactory<Contract> { ... }

Now all instances of Contracts have the method FindByUuid that only accepts instances of Contract . No need for overriding - in your case it´s actually hiding as there allready exists a member with that name in the base-class.
