< blockquote>这将帮助你

 string date =07/02/2011
 Respose.Write（string.format（ {0：dd / MM / yyyy}，日期））; 

这不是改变07/02/2011因为你刚刚把一个字符串转换为日期，但这将是一个日期的默认表示。表示为MM / dd / yyyy，由于可能在解释中出现错误而无法在逻辑上进行更改，因为不清楚07是月份还是日期（这也是给定日期的02）。



我自己来自荷兰，代表那里使用短划线（ - ）而不是斜线（/），日期从日而不是月开始。所以07/02/2011将成为02-07-2011。斜杠和短划线清楚地表明前两个值代表的是什么（日或月）。没有它，除非当天高于13，因为没有第13个月，所以真的没有办法知道。



所以，请你解释一下原因是什么反转日和月？如果你真的想，你可以使用Split方法，如：

 string [] split = date.Split（new Char [] {'\\'} ）; 
 //您应该检查数组的下限和上限
 string newDate = split [1] + split [0] + split [2]; 

你也可以使用自定义格式：

 string newDate = String.Format（{0：dd / MM / yyyy}，dt）; // dt是DateTime类型

祝你好运！

This will help you

string date="07/02/2011"
Respose.Write(string.format("{0:dd/MM/yyyy}",date));

It isn't "changing in" "07/02/2011" because you just did cast a string to date, but that would be the default representation of a date. The representation is "MM/dd/yyyy" and cannot logically be changed due to possible errors in interpretation because it is unclear if 07 is the month or the day (this also goes for 02 in the date given).

I myself am from the netherlands and the representation there is using a dash(-) instead of a slash(/) and the date is starting with the day instead of the month. So "07/02/2011" would become "02-07-2011". The slash and dash keep it clear what the first two values represent (either day or month). Without that there is really no way to know except when the day is above 13 because there is no 13th month.

So, could you please explain what the reason is to reverse day and month? If you really want to, you can just use the Split method like:

string [] split = date.Split(new Char [] {'\\'});
// You should need to check the lower and upper bound of the array 
string newDate = split[1] + split[0] + split[2];

You could also use a custom formatting:

string newDate = String.Format("{0:dd/MM/yyyy}", dt); // dt is of type DateTime

Good luck!
