C# DateTime和String转换

string time = "20160202";
DateTime.ParseExact(time,"yyyyMMdd",System.Globalization.DateTimeFormatInfo.CurrentInfo);

结果：

{2016/2/2 0:00:00}
    Date: {2016/2/2 0:00:00}
    Day: 2
    DayOfWeek: Tuesday
    DayOfYear: 33
    Hour: 0
    Kind: Unspecified
    Millisecond: 0
    Minute: 0
    Month: 2
    Second: 0
    Ticks: 635899680000000000
    TimeOfDay: {00:00:00}
    Year: 2016

DateTime CreateTime = new DateTime();
如果时间格式："yyyy-MM-dd HH:mm"
例如：string t="2016-02-02 11:15";
可以：DateTime.TryParse(t,out CreateTime);
也可以：Convert.ToDateTime(t);

结果：

{2016/2/2 11:15:00}
    Date: {2016/2/2 0:00:00}
    Day: 2
    DayOfWeek: Tuesday
    DayOfYear: 33
    Hour: 11
    Kind: Unspecified
    Millisecond: 0
    Minute: 15
    Month: 2
    Second: 0

 补充：

如果这么写：

DateTime.ParseExact("20161027152800","yyyyMMddhhmmss",System.Globalization.DateTimeFormatInfo.CurrentInfo);

是会报错的：Message: "该字符串未被识别为有效的 DateTime。"

因为：

上面的写法只能识别12时计时法;想24时计时法转换的↓

DateTime.ParseExact("20161027152800","yyyyMMddHHmmss",System.Globalization.DateTimeFormatInfo.CurrentInfo);

hh和HH...........

哈哈
