How to resolve this ?

If it is acceptable for your solution, then the easiest way is to construct all the data for insertion and then insert them all (it will cause a number of inserts). This is what Ranhiru Cooray has suggested in his answer - just iterate through all dates, construct each row and call insert for each of them.

BUT, if you want to do it by one DB call, then I would suggest creating a stored procedure in database, which gets these 3 parameters and then executes inserts inside it - by constructing insertion rows inside itself and executing each of them - still remaining in bounds of a single database call for your code or application.

I hope this helps!

DateTime start = DateTime.Parse("1/1/2010");
DateTime end = DateTime.Parse("1/30/2010");

        while(start <= end)
        {
            Console.WriteLine("Date : " + start.ToShortDateString());
            start = start.AddDays(1);
        }

This will help you get started :)
