如何将日期值格式化为yyyy/MM/dd?

问题描述：

你好!!

我只想将数据读取器返回的日期格式化为"yyyy/MM/dd"

我有一个DataReader和TextBox，我想在TextBox中设置DataReader值之一.此值表示SQL Server DB中的日期值.我做了以下事情:

Hello !!

I just want to format the returned date from the data reader into "yyyy/MM/dd"

I have a DataReader and TextBox, i want to set one of DataReader values in the TextBox ... This value represents a date value from SQL Server DB. I did the following:

txtDate.Text = Format(DR("ActionDate"),"yyyy/MM/dd")

还有一次我这样做:

and another time I did this:

Dim x As Date
x = DR("ActionDate")
txtDate.Text = x.ToString("yyyy/MM/dd")

以上方法中没有一种能很好地工作..尽管我在MSDN中进行了大量搜索，尝试了10种以上的解决方案，但没有白费了！！

no one of above methods working well .. although I searched a lot in MSDN and I tried more then 10 solutions but no in vain !!

Here is the answer with the code sample: http://msdn.microsoft.com/en-us/library/5hh873ya.aspx[^].

For more flexible option, see this: the class System.Globalization.DateTimeFormatInfo and the sample code provided: http://msdn.microsoft.com/en-us/library/system.globalization.datetimeformatinfo.aspx[^], in particular, pay attention for "SortableDateTimePattern" in the sample code and the class.

(如果此处使用以下格式:标准日期和时间格式字符串 [ ^ ]不能给您期望的结果，那么您可能需要检查您的区域性设置.

if the formats here: Standard Date and Time Format Strings[^] aren''t giving you the results you expect, then you may need to check your culture settings.
