c# - 以 "ddmmyy"格式对字符串数据进行排序

Question

我有几个数据字符串

  var stringData = new List<string> {"31/01/17 09:15:09",
                                            "1/02/17 09:15:09",
                                            "3/02/17 09:15:09",
                                            "4/02/17 09:15:09",
                                            "30/01/17 09:15:09",
                                            "8/01/17 09:15:09"};

        var orderedData = stringData.OrderBy(a => a);
        var orderedData1 = stringData.OrderByDescending(a => a);

有什么方法可以让我们以正确的排序顺序获取数据？

Answer 1

var orderedList = stringData.OrderByDescending(x => DateTime.Parse(x)).ToList();

编辑: ParseExact 将允许您指定用于解析的日期字符串的确切格式。

var orderedList = stringData.OrderByDescending(
                x => DateTime.ParseExact(x, "d/MM/yy hh:mm:ss", CultureInfo.InvariantCulture)).ToList();
