无法理解.Net中的日期时间相关代码 [英] Unable to understand Datetime related code in .Net

问题描述

我有一个代码写在一个页面的页面加载，我无法理解它..

有人可以解释一下..代码是：

 DateTime LastDateOfPreviousMonth; 
 LastDateOfPreviousMonth = Convert.ToDateTime（DateTime.Now.AddDays（（ -  1）* DateTime.Now.Day）.ToShortDateString（））; 
 
 txtStartDate.Value =  new  DateTime（LastDateOfPreviousMonth.Year，LastDateOfPreviousMonth.Month， 1 ）。ToString（  MM / dd / yyyy）; 
 txtEndDate.Value = LastDateOfPreviousMonth.ToShortDateString（）; 
 

它显示了Startdate和enddate文本框中的日期。

我是.net的新手..请帮助..！

解决方案

这看起来非常像家庭作业。如果是，我建议你们两个：

• 使用调试器，看看每一步发生了什么
• 有一个查看这些方法的文档
  
  
  • Convert.ToDateTime方法（字符串） [ ^ ]
  
  
  
  • DateTime.Now Property [ ^ ]
  
  
  
  • DateTime.AddDays方法 [ ^ ]
  
  
  

I have a code written on the page load of a page and i am not able to understand it..
can somebody please explain me that.. code is:

DateTime LastDateOfPreviousMonth;
           LastDateOfPreviousMonth = Convert.ToDateTime(DateTime.Now.AddDays((-1) * DateTime.Now.Day).ToShortDateString());

           txtStartDate.Value = new DateTime(LastDateOfPreviousMonth.Year, LastDateOfPreviousMonth.Month, 1).ToString("MM/dd/yyyy");
           txtEndDate.Value = LastDateOfPreviousMonth.ToShortDateString();

It shows which dates in Startdate and enddate textbox.
I am new to .net.. Please help..!

解决方案

This looks awfully like a homework. If true, I suggest that you both:

• use the debugger and see what happens in each step
• have a look at the documentation for these methods
  
  • Convert.ToDateTime Method (String)[^]
  
  
  • DateTime.Now Property[^]
  
  
  • DateTime.AddDays Method[^]
