Datetime.ToString（）C＃无法正常工作 [英] Datetime.ToString() C# not working as expected

问题描述

从

我期望 2015年7月29日，但收到了 2015年7月29日 !!!为什么？

解决方案

看起来像您的您的 /library/system.globalization.cultureinfo.currentculture%28v=vs.110%29.aspx> CurrentCulture 是-，这就是 / 字符替换为它的原因。

/ 自定义格式说明符的特殊含义是用当前的区域性或提供的区域性日期分隔符替换我。

您有几种选择，要么逃避用单引号（或逐字字符串中的 \ / ）或使用以 / 作为 DateSeparator ，例如 不变文化 。

  string s = DateTime.Now.ToString（ M'/'d'/'yyyy）; 
 string s = DateTime.Now.ToString（@ M\ / d\ / yyyy）; 
 string s = DateTime.Now.ToString（ M / d / yyyy，CultureInfo.InvariantCulture）; 
  

From msdn it seems like I can create my own format with Datetime.ToString() method by using M, m, d, y etc. But when I tried one it didn't worked as expected, snipped below is the issue.

I was expecting 7/29/2015 but received 7-29-2015 !!! why?

解决方案

Looks like your DateSeparator of your CurrentCulture is - and that's why / character replace itself to it.

"/" custom format specifier has a special meaning as replace me with current culture or supplied culture date separator.

You have a few options, you either escape it with single quotes (or \/ in a verbatim string literal) or use a culture that has / as a DateSeparator like InvariantCulture.

string s = DateTime.Now.ToString("M'/'d'/'yyyy");
string s = DateTime.Now.ToString(@"M\/d\/yyyy");
string s = DateTime.Now.ToString("M/d/yyyy", CultureInfo.InvariantCulture);
