如何在C#中获得正确的时间戳
问题描述：
我想在我的应用程序中获得有效的时间戳，所以我写道:
I would like to get valid timestamp in my application so I wrote:
public static String GetTimestamp(DateTime value)
{
return value.ToString("yyyyMMddHHmmssffff");
}
// ...later on in the code
String timeStamp = GetTimestamp(new DateTime());
Console.WriteLine(timeStamp);
输出:
000101010000000000
我想要类似的东西:
20140112180244
我做错了什么?
答
您的错误是使用 new DateTime()，它返回0001年1月1日00:00:00.000而不是当前日期，并且时间.获取当前日期和时间的正确语法是
Your mistake is using new DateTime(), which returns January 1, 0001 at 00:00:00.000 instead of current date and time. The correct syntax to get current date and time is DateTime.Now, so change this:
String timeStamp = GetTimestamp(new DateTime());
对此:
String timeStamp = GetTimestamp(DateTime.Now);
