推荐答案

您可以尝试 DateTimeFormat 来找出当前星期的开始日期和 Linq 生成字符串：

You can try DateTimeFormat to find out current week's starting date and Linq to generate the string:

  DateTime startOfWeek = DateTime.Today.AddDays(
      (int) CultureInfo.CurrentCulture.DateTimeFormat.FirstDayOfWeek - 
      (int) DateTime.Today.DayOfWeek);

  string result = string.Join("," + Environment.NewLine, Enumerable
    .Range(0, 7)
    .Select(i => startOfWeek
       .AddDays(i)
       .ToString("dd-MMMM-yyyy")));

如果是 zh-CN 文化， 'll get（一周从 Sunday 开始）

In case of en-US culture you'll get (week starts from Sunday)

26-March-2017,  // <- starts from Sunday
27-March-2017,
28-March-2017,
29-March-2017,
30-March-2017,
31-March-2017,
01-April-2017

如果 ru-RU 您将获得的文化（每周从星期一开始）

In case of, say, ru-RU culture you'll get (week starts from Monday)

27-марта-2017,  // <- Starts from Monday
28-марта-2017,
29-марта-2017,
30-марта-2017,
31-марта-2017,
01-апреля-2017,
02-апреля-2017
