Inject appropriate class C#

I need some advice on how to better structure my classes.

I have generic interface and class:

public interface IReader
{
        IEnumerable<Change> ReadChanges(string log, int count, string from);
}

public class Reader : IReader
    {
        private readonly MongoDb _db;

        public StageChangesReader(MongoDb db)
        {
            _db = db;
        }

        public IEnumerable<Change> ReadChanges(string log, int count, string from)
        {
             //....
        }
    }

Then I made three other classes that use this reader (they implement the same method and the only difference is log that I pas) something like this:

 public class SpecificReader
    {
        private readonly IReader _reader;

        public SpecificReader(IReader reader)
        {
            _reader = reader;
        }

        public IEnumerable<Change> ReadChanges(int count, string from)
        {
            return _changesReader.ReadChanges("specific log", count, from);
        }
    }

finally in the third class I want to inject these and based on the type use specific logging in the function:

var changes = _type == MyType.SpecificReader
                ? _specificReader.ReadSpecific(_count, from)
                : _somethingElse.ReadSomethingElse(_count, from);

I would like to make this more generic that instead of having if I could pass this one generic method.

so it would be like:

var changes = _Reader.ReadChanges(_count, from)

Is that possible?

Considering adding a method in your interface and either overwriting it in your derived concrete classes, so you can call IConcreteClass.LogMethod() on all of them, making them responsible for the way they log.
