改变文化不会改变日期时间格式。 [英] changing culture does not change date time Format.

问题描述

输入日期是2015-01-30

entered date is 2015-01-30

System.Globalization.CultureInfo en = new System.Globalization.CultureInfo("en-US");
     System.Threading.Thread.CurrentThread.CurrentCulture = en;
     DateTime dt =Convert.ToDateTime(txbuyerOrder_date.Text, en.DateTimeFormat);

dt is always {30/01/2015 12:00:00 AM}

whether culture is en-GB or en-US or anything else

推荐答案

DateTime没有 有 格式 - 它自任意时间点起存储为毫秒数，所以它只有一个数字！



只有在准备好呈现时才会获得格式ToString方法的用户bymenas，通过调用显式：

A DateTime doesn't have a format - it is stored as a number of milliseconds since an arbitrary point in time, so all it has is a number!

It only acquires a format when it is prepared for presentation to a user bymenas of the ToString method, either explicitly via a call:

string myDate = dt.ToString();

或隐含地：

Or implicitly:

Console.WriteLine(dt);

或

Or

string myDate = "The date is " + dt;

完成转换为字符串后，在执行转换的PC上生效的文化控制如何生成的字符串已格式化。



[edit]

您可以通过指定所需的确切输出格式来覆盖默认格式 - 请参阅此处： 格式化日期时间以显示 - 格式字符串说明 [ ^ ]

When the conversion to a string is done, the culture in effect on the PC doing the conversion controls how the resulting string is formatted.

[edit]
You can override the default formatting by specifying the exact output format you want - see here: Formatting a DateTime for display - format string description[^]
