获得一天的后缀使用则DateTime.ToString时，（） [英] Getting day suffix when using DateTime.ToString()

问题描述

是否有可能包括格式化使用则DateTime.ToString（）？日期的当天后缀

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

例如我想打印以下格式的日期 - 周一7月27日2009年。但2009年7月的最近的例子我能找到使用则DateTime.ToString（）是周一27

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.

我能做到这一点有则DateTime.ToString（）还是我将不得不回落到自己的code？

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，我总是用/引用的 SteveX字符串格式化 有没有出现在任何可用的变量中的任何日，但你可以轻松地构建一个字符串

As a reference I always use/refer to SteveX String Formatting 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, (?));

您将不得不提供一个ST1，次2，RD为3，而对于所有其他日，并可能是内衬用：言

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.

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