为什么列表仅包含等于currentDate = DateTime.Now.Date的相同日期？

Question

const int IterationsPerDay = 2;DateTimeOffset currentDate = DateTime.Now.Date;int dayCount = 0;for (int j = 0; j < ((IterationsPerDay * 30) / ClientsList.Count); j += IterationsPerDay){    for (int f = 0; f < IterationsPerDay; f++)    {        int iterationIndex = j + f;        if (iterationIndex < productsOfSameCategory.Count)        {           Client _client = new Client();           _client.Name = ClientsList[iterationIndex].Name;           _client.Date = currentDate;           VisitsList.Add(_client);        }        if (iterationIndex < productsOfSameCategory.Count)        {           Client _client = new Client();           _client.Name = ClientsList[iterationIndex-ClientsList.Count].Name;           _client.Date = currentDate;           VisitsList.Add(_client);        }    }    currentDate.AddDays(1);}在VisitsList应该得到加给它的所有30个日期。每个日期应有两个客户，因此列表中应有60条记录。为什么循环只添加第一个日期？
