How to use Reflection in linq queries ?

Hi

I'm looking for a way to use reflection in my linq queries to increase code reusability. for example, i want to change this method :

private Orders GetObjectGraph(MyDbContext dbContext, int orderID)
{
	return dbContext.Orders.Include(o => o.OrderDetails).AsNoTracking().FirstOrDefault(o => o.OrderID == orderID);
}

To something like this :

private object GetObjectGraph(MyDbContext dbContext, string masterEntityName, string detailsEntityName, string masterFieldName, object masterFieldValue)
{
	return dbContext[masterEntityName].Include(o => o[detailsEntityName]).AsNoTracking().FirstOrDefault(o => o.[masterFieldName] == masterFieldValue);
}

Can anybody help me how to accomplish this task ?

Thanks in advance
