Converting from closed generics to open generics

问题

I am looking for a way to convert the following closed generics statement to open generic statement, i.e. I don't want repeat the same for entities like User, Employer, etc.

Closed type using User:

UnityContainer.RegisterType<Func<IDataContextAdapter, IRepository<User>>>(
    new InjectionFactory(c => 
                    new Func<IDataContextAdapter, IRepository<User>>(
                        context => new Repository<User>(context))
        )
 );

I tried converting to Open generics by applying typeof(..) operation, but didn't had much success.

Any Ideas?

回答1:

Make generic Function

public void Bla<T>() where T:class
{
UnityContainer.RegisterType<Func<IDataContextAdapter, IRepository<T>>>(
    new InjectionFactory(c => 
                    new Func<IDataContextAdapter, IRepository<T>>(
                        context => new Repository<T>(context))
        )
 );
}
