c# - 再帰を使用してC#.netで月に基づいて日付範囲を分割する方法

Question

日付範囲をそれぞれの月に分割したいと思います。たとえば、次のようなデータがあります。

startdate   enddate
2013-04-04  2014-01-31

上記のデータをこの方法で表示できるようにしたい：

 startdate   enddate     
 2013-04-04  2013-04-30
 2013-05-01  2013-06-30  --(2 month difference)
 2013-07-01  2013-08-31
 2013-09-01  2013-10-31
 2013-11-01  2013-12-31
 2014-01-01  2014-01-31

List誰かが使用と再帰を手伝ってくれますか?

再帰なしで試したサンプルコード

          List<DateInformation> lDateCol1 = new List<DateInformation>();
          List<DateInformation> lDateCol = new List<DateInformation>();
          lResult.DateFrom = '4/4/2013';
          lResult.DateUntil = '31/01/2014';


        DateTime Today;
        DateTime FirstDate = DateTime.MaxValue;
        DateTime LastDate = DateTime.MinValue;
        DateTime NextFirstDate = DateTime.MaxValue;
        DateTime NextLastDate = DateTime.MinValue;
        DateTime InputStartDate = DateTime.MaxValue;
        DateTime InputEndDate = DateTime.MinValue;
        Today = lResult.DateFrom;
        FirstDate = new DateTime(Today.Year, 1, 1);
          int monthsApart = Math.Abs(12 * (lResult.DateFrom.Year - lResult.DateUntil.Year) + lResult.DateFrom.Month - lResult.DateUntil.Month)


        for (int daycount = 0; daycount < 12; daycount += noofmonths)
        {
          if (count == 0)
          {
            NextLastDate = FirstDate.AddMonths(noofmonths).AddDays(-1);
            lDateCol1.Add(new DateInformation(FirstDate, NextLastDate));
          }
          if (count > 0)
          {
            NextFirstDate = NextLastDate.AddDays(1);
            NextLastDate = new DateTime(NextFirstDate.Year, NextFirstDate.Month, 1).AddMonths(noofmonths).AddDays(-1);
            lDateCol1.Add(new DateInformation(NextFirstDate, NextLastDate));
          }
          count = count + 1;
        }
        for (count = 0; count <= lDateCol1.Count - 1; count++)
        {
          if ((lDateCol1[count].DateFrom <= lResult.DateFrom) && (lResult.DateFrom <= (lDateCol1[count].DateUntil)))
          {
            InputStartDate = lResult.DateFrom;
            InputEndDate = lDateCol1[count].DateUntil;
            NextFirstDate = InputStartDate;
            NextLastDate = InputEndDate;
            lDateCol.Add(new DateInformation(NextFirstDate, NextLastDate));
            break;
          }
        }

        for (int daycount = 0; daycount <= monthsApart; daycount += noofmonths)
        {
          NextFirstDate = NextLastDate.AddDays(1);
          NextLastDate = new DateTime(NextFirstDate.Year, NextFirstDate.Month, 1).AddMonths(noofmonths).AddDays(-1);
          if (!(NextLastDate < lResult.DateUntil))
          {
            lDateCol.Add(new DateInformation(NextFirstDate, lResult.DateUntil));
            break;
          }
          else
          {
            lDateCol.Add(new DateInformation(NextFirstDate, NextLastDate));
          }
        }
      }
