在2个文本框中找到日期和时间之间的时差，然后将答案放在第三个文本框中. [英] Find the difference between the date and time in 2 text boxes and place the answer in a third.

问题描述

我有一个按钮，用于将当前日期和时间(现在)放置在文本框中.稍后按下时，另一个按钮会将当前日期和时间放置在另一个文本框中.

我希望单击另一个按钮时，第三个文本框中显示两个日期和时间之间的差异.

我该怎么办?

谢谢

I have a button that places the current date and time (Now) in a text box. Another button places the current date and time in another text box when pressed later.

I would like the difference between the 2 dates and times to appear in a third text box when another button is clicked.

How do I do this?

Thank You

推荐答案

好吧，Abhinav发送的代码编写得不好，而且显然没有经过他的测试.他写道:

Well, the code that Abhinav sent is not well-written, and obviously not tested by him. He wrote:

TimeSpan dt = Convert.ToDateTime(text1.text) - Convert.ToDateTime(text2.text);
textbox3.text = "Days  " + dtDiff.Days.ToString() +  
   "Hours " + dtDiff.TotalHours() + 
   "Minutes " + dtDiff.TotalMinutes();

首先，我假设text2应该在text1之后，因此您实际上想从text1减去text2，但是我确定您已经弄清楚了.
其次，他声明了一个名为"dt"的TimeSpan，然后引用了"dtDiff".
第三，为了显示小时数，他使用了TotalHours(). 会给你几个小时的两个日期之间的差异.
您真正想要的是我刚刚测试的

First, I would assume that text2 should be after text1, so you would actually want to subtract text2 from text1, but I''m sure you figured that out.
Second, he declared a TimeSpan called "dt" and then referenced "dtDiff".
Third, to display hours, he used TotalHours(). TotalHours() will give you the difference between the two dates in only hours.
What you really want, and what I just tested would be

Dim dtDiff As TimeSpan = Convert.ToDateTime(txtDate2.Text) - _
                         Convert.ToDateTime(txtDate1.Text)
txtDateDiff.Text = dtDiff.Days & " Days, " & dtDiff.Hours & _
                   " Hours, " & dtDiff.Minutes & " Minutes, " & _
                   dtDiff.Seconds & " Seconds"

(它在VB中是因为您没有指定使用的语言，并且我已经在VB中设置了可以测试它的表单.

(It''s in VB because you didn''t specify which language you were working in, and I had a form already set up in VB where I could test it.

感谢帮助William.效果很好！

Thanks for the help William. That worked great!

在按钮的click事件上，您需要添加如下代码-

On a button''s click event, you need to add code as follows -

TimeSpan dt = Convert.ToDateTime(text1.text) - Convert.ToDateTime(text2.text);
textbox3.text = "Days  " + dt.Days.ToString() +  
   "Hours " + dt.TotalHours() + 
   "Minutes " + dt.TotalMinutes();
