到目前为止的任何努力？ Google [ ^ ]有很多主题。

基本上，你需要利用 TimeSpan [ ^ ]。

Any effort so far? Google[^] has hell lot of topics on this.

Here are few of those:

Basically, you need to make use of TimeSpan[^].

这可以使用输入T. imeSpan。例如：假设我们想知道最大值之间的天数。和分钟。 DateTime Type的值并在Console窗口中显示，然后我可能会写出类似的内容：

This can be easily accomplished using an object of Type "TimeSpan". For example: let's assume that we want to know the number of days between the max. and min. values for the DateTime Type and show it in a Console window, then I may write something like:

DateTime d1=DateTime.MinValue;
DateTime d2=DateTime.MaxValue;
TimeSpan span=d2-d1;
Console.WriteLine( "There're {0} days between {1} and {2}" , span.TotalDays, d1.ToString(), d2.ToString() );

假设你的DateTimes被称为start和end。

DateTime start = new DateTime（2009,6,14）;

DateTime end = new DateTime（2009,12,14）;



我们已将我们的日期时间设定为2009年6月14日和2009年12月14日。



现在，让我们找到两者之间的区别。为此，我们创建一个TimeSpan：

TimeSpan差异=结束 - 开始;



使用此TimeSpan对象，您可以通过多种不同方式表达时间差异。但是，你特意要求天数的差异，所以这里是你如何得到的：

Console.WriteLine（天数差异：+ +差异。天数）;



因此，该物业被称为TimeSpan.Days。

Let's say that your DateTimes are called start and end.
DateTime start = new DateTime(2009, 6, 14);
DateTime end = new DateTime(2009, 12, 14);

We have established our DateTimes to June 14, 2009 and December 14, 2009.

Now, let's find the difference between the two. To do this, we create a TimeSpan:
TimeSpan difference = end - start;

With this TimeSpan object, you can express the difference in times in many different ways. However, you specifically asked for the difference in days, so here's how you can get that:
Console.WriteLine("Difference in days: " + difference.Days);

Thus, the property is called TimeSpan.Days.
