Question

I have a abstract generic class. I want to define a method inside there so I won’t have to do it in all derived classes.

Basically I need to fetch a repository class based on the Type the generic class will be.

I fetch the repoistories through another class which is non generic.

How can I let that class return a generic repository based on the type the generic caller has?

I was hoping for something like this.

public IRepository<T> Table<T>()
{
    return _container.Resolve<IRepository<T>>();
}

If it would be a property it will be even better.

I don’t see the problem. You could write code like this that compiled. Does this not accomplish what you want?

interface IRepository<T>
{
    T GetData();
}

class Container
{
    private object[] data = null;

    public T Resolve<T>()
    {
        return(T)data.First(t => t.GetType() is T);
    }
}

abstract class Handler<T>
{
    private Container _container;

    public IRepository<T> Table
    {
        get
        {
            return _container.Resolve<IRepository<T>>();
        }
    }
}
