{//得到完整的月，日
string txt = arr[d.Date.Month][d.Date.Day];
if (txt != string.Empty)//看下面是否有东西
{//获取当前的日期并转化为短日期格式
string day = e.Day.Date.ToShortDateString();
//循环数据视图中的每一行
foreach (DataRow dr in ds
(day).Rows)
{
c.Controls.Clear();
c.Controls.Add (new LiteralControl("<a href='http://www.baidu.com"+ day+ "'><b>"+e.Day.Date.Day+"</b></a>"));
}
//如果有的话吗，就在数字日期后面换行显示
c.Controls.Add(new LiteralControl("<br>" + txt));
}
}
catch(Exception exe)
{
Response.Write (exe.ToString ());
}
}

}
}
}

效果图：

1.通过选择Droplist来选择日期的类型

2.获取日历中选择的日期

3.给日历设置日期

4.遗留问题：绑定数据库，添加数组，显示特殊节日，这个没有做好。
