For some map configuration:

var mapper = new MapperConfiguration(cfg =>
{
    cfg.CreateMap<Source, Destination>().ForMember(dst => dst.C_First_Name, opt => opt.MapFrom(src => src.FirstName));
});

You can define a method like this:

public string GetDestinationPropertyFor<TSrc, TDst>(MapperConfiguration mapper, string sourceProperty)
{
    var map = mapper.FindTypeMapFor<TSrc, TDst>();
    var propertyMap = map.GetPropertyMaps().First(pm => pm.SourceMember == typeof(TSrc).GetProperty(sourceProperty));

    return propertyMap.DestinationProperty.Name;
}

Then use it like so:

var destinationName = GetDestinationPropertyFor<Source, Destination>(mapper, "FirstName");
