本文实例报告了asp.net基于Calendar完成blog日历功用。分享给人人供人人参考，细致以下：
怎样用.net的Calendar控件来完成blog中站点日历的结果呢,我们晓得站点日历最主要的功用就是,展现在哪天blog主人写了日记,点击日期,你将进入所选日期的日记列表,
起首，我们晓得.net中的服务器控件是会举行Postback的，Calendar控件中的第一天在点击时，就会举行一次postback我们要做的就是转变它默许的链接，使它不触发postback事宜，其次，就是要晓得哪一天有无日记。至于有无日记，就要去数据库查询了。
在Calendar中有一个DayRender事宜，该事宜在显现每一天时触发，我们能够从这里入手,起首定义一个数组变量:
private int[] arrCurrentDays, arrPreDays, arrNextDays; //三个变量分别是当前月，前一月，和下一个月 private int intCurrentMonth, intPreMonth, intNextMonth; //三个整型数组寄存相对月份写有blog的日期
然后在Calendar的DayRender事宜中写下以下代码:
CalendarDay d = ((DayRenderEventArgs)e).Day;
TableCell c = ((DayRenderEventArgs)e).Cell;
// 初始化当前月有Blog的日期数组
if (intPreMonth == 0)
{
intPreMonth = d.Date.Month; // 注重：日历控件初始化时我们获得的第一个月并非当前月，而是前一个月的月份
intCurrentMonth = intPreMonth + 1;
if (intCurrentMonth > 12)
intCurrentMonth = 1;
intNextMonth = intCurrentMonth + 1;
if (intNextMonth > 12)
intNextMonth = 1;
arrPreDays = getArrayDay(d.Date.Year, intPreMonth); //获得前一个月有blog的日期数组
arrCurrentDays = getArrayDay(d.Date.Year, intCurrentMonth);//获得当月有blog的日期数组
arrNextDays = getArrayDay(d.Date.Year, intNextMonth);//获得下个月有blog的日期数组
}
int j = 0;
if (d.Date.Month.Equals(intPreMonth))
{
while (!arrPreDays[j].Equals(0))
{
if (d.Date.Day.Equals(arrPreDays[j]))
{
c.Controls.Clear();
c.Controls.Add(new LiteralControl("<a href="day.aspx?year=" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" mce_href="day.aspx?year=" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" " + d.Date.Year + "&month=" +
d.Date.Month + "&day=" + d.Date.Day + ">" + d.Date.Day + "</a>"));
}
j++;
}
}
else if (d.Date.Month.Equals(intCurrentMonth))
{
while (!arrCurrentDays[j].Equals(0))
{
if (d.Date.Day.Equals(arrCurrentDays[j]))
{
c.Controls.Clear();
c.Controls.Add(new LiteralControl("<a href="day.aspx?year=" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" mce_href="day.aspx?year=" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" " + d.Date.Year + "&month=" +
d.Date.Month + "&day=" + d.Date.Day + " title=检察"+d.Date.Day+"日日记>" + d.Date.Day + "</a>"));
}
j++;
}
}
else if (d.Date.Month.Equals(intNextMonth))
{
while (!arrNextDays[j].Equals(0))
{
if (d.Date.Day.Equals(arrNextDays[j]))
{
c.Controls.Clear();
c.Controls.Add(new LiteralControl("<a href="day.aspx?year=" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" mce_href="day.aspx?year=" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" " + d.Date.Year + "&month=" +
d.Date.Month + "&day=" + d.Date.Day + ">" + d.Date.Day + "</a>"));
}
j++;
}
在这里我们注重的是getArrayDay()要领是从数据库里查询当月是不是有日记的要领,它返回的是一个数组,我写的内容以下:
public int[] getArrayDay(int intYear, int intMonth)
{
int[] intArray = new int[31];
//从数据库里拔取符合要求的纪录，将日期存入数组
string strSql = "select data from test where year(data)=" + intYear +
" and month(data)=" + intMonth;
//挪用DbHelperOleDb自定义类中的ExecuteReader要领,它返回的是一个OleDbDataReader型
OleDbDataReader dr = dbAccess.DbHelperOleDb.ExecuteReader(strSql);
int i = 0;
while (dr.Read())
{
if (i == 0)
{
intArray[i] = Convert.ToDateTime(dr["data"].ToString()).Day;
string a=Convert.ToString(intArray[i]);
i++;
}
else if (Convert.ToDateTime(dr["data"].ToString()).Day != intArray[i - 1])
{
intArray[i] = Convert.ToDateTime(dr["data"].ToString()).Day;
i++;
}
}
return intArray;
}
