如何在C＃中将字符串日期转换为以下日期格式dd / MM / yyyy t：m：s(How to convert string date to following date format dd/MM/yyyy t:m:s in C#)

我需要将日期格式从字符串转换为dd/MM/yyyy tt:mm:ss in C＃例如convert

string = "2015-07-21T23:00:00.000Z"

至

{21/07/2015 00:00:00}

I need to convert date format from string to dd/MM/yyyy tt:mm:ss in C# for example convert

string = "2015-07-21T23:00:00.000Z"

to

{21/07/2015 00:00:00}

最满意答案

我会使用DateTimeStyles.RoundtripKind枚举将其解析为DateTime ，因为它是ISO 8601格式，然后使用它的Date属性将它的时间部分设置为午夜。

var dt = DateTime.Parse("2015-07-21T23:00:00.000Z", null, DateTimeStyles.RoundtripKind); Console.WriteLine(dt.Date.ToString("dd'/'MM'/'yyyy HH:mm:ss")); // 21/07/2015 00:00:00

这是一个demonstration 。

I would parse it to DateTime with DateTimeStyles.RoundtripKind enumeration since it is ISO 8601 format then use it's Date property to set it's time part to midnight.

var dt = DateTime.Parse("2015-07-21T23:00:00.000Z", null, DateTimeStyles.RoundtripKind); Console.WriteLine(dt.Date.ToString("dd'/'MM'/'yyyy HH:mm:ss")); // 21/07/2015 00:00:00

Here a demonstration.
