使用 DateTime.ToString() 时获取日期后缀 [英] Getting day suffix when using DateTime.ToString()

问题描述

在使用 DateTime.ToString() 格式化日期时是否可以包含日期后缀?

Is it possible to include the day suffix when formatting a date using DateTime.ToString()?

例如，我想以以下格式打印日期 - 2009 年 7 月 27 日星期一.但是，我可以使用 DateTime.ToString() 找到的最接近的示例是 2009 年 7 月 27 日星期一.

For example I would like to print the date in the following format - Monday 27th July 2009. However the closest example I can find using DateTime.ToString() is Monday 27 July 2009.

我可以使用 DateTime.ToString() 来做到这一点，还是我将不得不退回到我自己的代码?

Can I do this with DateTime.ToString() or am I going to have to fall back to my own code?

推荐答案

作为参考，我总是使用/参考 [SteveX String Formatting] 1并且似乎没有任何th"在任何可用变量中，但您可以使用

As a reference I always use/refer to [SteveX String Formatting] 1 and there doesn't appear to be any "th" in any of the available variables but you could easily build a string with

string.Format("{0:dddd dd}{1} {0:MMMM yyyy}", DateTime.Now, (?));

然后你必须提供一个st"对于 1，nd"对于 2，rd"为 3，和th"对于所有其他人，并且可以与?:"声明.

You would then have to supply a "st" for 1, "nd" for 2, "rd" for 3, and "th" for all others and could be in-lined with a "? :" statement.

var now = DateTime.Now;
(now.Day % 10 == 1 && now.Day % 100 != 11) ? "st"
: (now.Day % 10 == 2 && now.Day % 100 != 12) ? "nd"
: (now.Day % 10 == 3 && now.Day % 100 != 13) ? "rd"
: "th"
