请解决我的问题

Hi,
How to add academic years in dropdownlist(Programatically).

Eg: 2010-2011,
2011-2012 etc.

Please solve my problem

推荐答案

使用日期时间 [ ^ ]来获取年份，并进行字符串串联(例如2010-2011年)&将其添加到下拉列表.

DateTime.Now.Year()将返回当前年份.

同意普拉萨德.将值存储在数据库中将其加载到下拉列表中.考虑这是您的表格(Academic_Years).

Use DateTime[^] to get the years, do string concatenation(Ex. 2010-2011) & add it to dropdownlist.

DateTime.Now.Year() will return current year.

EDIT

Agree with Prasad. Store values in database & load it in dropdownlist. Consider this is your table(Academic_Years).

Years
--------------
2008-2009
2009-2010
2010-2011
2011-2012
--------------

使用以下查询选择数据

Use below query to select the data

SELECT * FROM Academic_Years

编写类似下面的代码

Write code something like below

DataTable dt = GetYears();//Custom function to load Academic years from database
dropdownlist.DataSource = dt;
dropdownlist.DataBind();

Hari，

请在Page_Load()事件中使用此代码

Hi Hari,

Please use this code in the Page_Load() event

if (!Page.IsPostBack)
        {
            for (int i = 2000; i <= 2012; i++)
            {
                int next = i + 1;
                DropDownList1.Items.Add(i.ToString() + "-" + next.ToString());
            }
        }

如果此操作可以解决您的问题，请设为已解决"，
