Dear Sir/Madam,
I have a date textbox in my project. My requirement is Default date for end year March 31. I need to change this year dynamically year by year.

For Example

1.If My date of joining is 14-02-2012,it will show in the textbox 31-03-2011,
If My date of joining is 01-04-2012, it will show in the textbox 31-03-2012,


Note:

1.This will happen on page load

推荐答案

这很简单.您可以使用DateTime构造函数来初始化日期，方法是分别提供年，月和日值，如以下示例所示.

It is very simple. You can initiate date with DateTime constructor by providing year, month and day values separately as shown in following example.

DateTime dateTime=new DateTime((DOJ.Month>3?DOJ.Year:DOJ.Year-1), 3, 31);    

希望有帮助！

Hope this help!

您好，

以下代码可能会帮助您:-

Hi,

Following code may help you:-

int icurrMonth = DateTime.Now.Month;
string sYear="";

  if (icurrMonth < 4)//If joining month is April or less then Previous year
  {
    sYear = (DateTime.Now.Year - 1).ToString();
  }
  else //After April Current Year
  {
   sYear = DateTime.Now.Year.ToString();

  }

txtBox.Text = "31-03-" + sYear;

注意:1.将"txtBox"替换为"TextBox ID"
2.将"DateTime.Now"替换为加入日期"

Note : 1. Replace "txtBox" with your "TextBox ID"
2. Replace "DateTime.Now" with "Date of Joining"
