在字符串 C# 中以特定格式返回两个日期时间之间的日期

Question

我有 2 种日期时间格式作为出发日期和到达日期，例如 25/04/2014 作为出发和 22/04/2014 作为到达，现在我希望返回这两者之间的日期如下： 22/04/2014|23/04/2014|24/04/2014|25/04/2014 在 C# 中，您对此有任何想法吗？

Answer 1

您可以避免使用 Linq 键入循环

StringBuilder sb = new StringBuilder();
DateTime arrival = new DateTime(2014,4,22);
DateTime departure = new DateTime(2014,4,25);
int days = Convert.ToInt32((departure - arrival).TotalDays);
var rng = Enumerable.Range(0,days+1).ToList();
rng.ForEach(r => sb.Append(arrival.AddDays(r).ToShortDateString() + "|"));
sb.Length--;
Console.WriteLine(sb.ToString());

Answer 2

var startDate = new DateTime(2014, 4, 22);
var endDate = new DateTime(2014, 4, 25);
var sb = new StringBuilder();
while (startDate <= endDate)
{
    sb.AppendFormat("|{0}", startDate.ToString("dd/MM/yyyy", CultureInfo.InvariantCulture)); 
    startDate = startDate.AddDays(1);
}
Console.WriteLine(sb.ToString().Substring(1));

Answer 3

喜欢：

var startDate = new DateTime(2014, 04, 25);
var endDate = new DateTime(2014, 04, 29);
var currentDate = startDate;
while (currentDate <= endDate)
{
       Console.WriteLine(currentDate);
       currentDate = currentDate.AddDays(1);
}

。但格式正确，但这将是视图逻辑。

瞧：

        DateTime start = new DateTime(2014, 4, 24);
        DateTime end = new DateTime(2014, 4, 22);
        DateTime current = start < end ? start : end;
        DateTime stop = start < end ? end : start;
        List<DateTime> dates = new List<DateTime>();
        while (current <= stop)
        {
            dates.Add(current);
            current = current.AddDays(1);
        }
        StringBuilder sb = new StringBuilder();
        foreach (DateTime dt in dates)
        {
            if (sb.Length > 0)
                sb.Append("|");
            sb.Append(dt.ToString("dd/MM/yyyy"));
        }
        Console.WriteLine(sb.ToString());
