我必须更改DateTime格式. [英] I have to change DateTime format.

问题描述

我制作了一个简单的Employee Presence应用程序(实际上，我制作的每个应用程序都在发生这种情况.我是C#的新手.)当我尝试在其他计算机上运行它时，它没有运行，并给出了无效的dateTime错误.所以我更改了与我相同的那台机器的DateTime格式.运行成功.那我该怎么办.我不想在每台计算机上更改日期时间格式.

I made a simple Employee Presence Application (actually this is happening with every applications I make. I am new to C#.). When I tried to run it on other machine it didn''t run and gave an error of Invalid dateTime. So I changed DateTime Format of that machine same as mine. It ran successfully. So what can I do. I don''t want to change datetime format on every machines.

推荐答案

问题尚不清楚.使用.NET，您可以读取任何格式的时间，并在输出时产生任何格式.请查看方法Parse，ParseExact，TryParse，TryParseExact和ToString的数量:

有关格式说明符，请参见:

http://msdn.microsoft.com/en-us/library/8kb3ddd4.aspx [ ^ ].

此外，请确保仅在确实需要时才从字符串解析并输出数据到字符串.我看到很多问题，查询者倾向于使用表示数据的字符串而不是数据本身.这是完全错误的方法.

The problem is not clear. With .NET, you can read time in any format and produce any format on output. Please see the number of methods Parse, ParseExact, TryParse, TryParseExact and ToString:
http://msdn.microsoft.com/en-us/library/system.datetime.aspx[^].

For format specifiers, please see:
http://msdn.microsoft.com/en-us/library/az4se3k1.aspx[^],
http://msdn.microsoft.com/en-us/library/8kb3ddd4.aspx[^].

Besides, make sure you parse from string and output data to string only when it is really required. I saw many questions where the inquirers tend to work with strings representing data instead of data itself. This is totally wrong approach.
