语言-> C#

The above syntax is same as which i got by the method "DateTime.Now.ToString()" for current time of the system..

language --> C#

推荐答案

尝试:

DateTime.Now.ToString("dd/MM/yyyy hh:mm:ss tt");

从在线文档 [

From the online documentation [^]on Date and Time formatting:
tt: Displays the A.M./P.M. designator for the specified DateTime.

当您没有告诉我们要转换为"DD/MM/YYYY HH:MM"的内容时，很难告知您:SS AM/PM"格式.

如果登录时间来自WMI，则它将是Distributed Management Task Force(DMTF)格式的字符串.在这种情况下，请使用System.Management.ManagementDateTimeConverter类.

It''s difficult to advise when you haven''t told us what it is you are trying to convert to "DD/MM/YYYY HH:MM:SS AM/PM" format.

If the login time came from WMI then it will be a string in Distributed Management Task Force (DMTF) format. In which case use the System.Management.ManagementDateTimeConverter class.

此代码应该有效:

This code should work:

DateTime.Now.ToString("dd/MM/yyyy hh:mm:ss tt");

但是，默认的DateTime.Now.ToString()格式可以通过本地化设置进行调整.例如，如果将当前线程的语言环境更改为"en-au"，则将获得带有AM/PM的上述格式.每当您将其提供给SQL插入/更新

However, the default DateTime.Now.ToString() format could be adjusted through your localization settings. If you change the locale of the current thread to "en-au" for example, you will get the above format with the AM/PM. Be careful with these formatting whenever you give it to an SQL insert/update
