如何动态日历创建在asp.net?

解决方案

您好，

请使用下面提到的代码创建日历这个：

 StringBuilder sb =  new  StringBuilder（）; 
 sb.Append（ < table style = border：2px solid; width： 100％;  >< tr>< th colspan =  7    style = text-align：center; height：40px ;  > + DateTime.Now.ToString（   Y）+  < / th>< / tr>< tr>< th style = text-align：center;  > Su< / th>< th style = text-align：center;  > Mo< / th>< th style = text-align：center;  > ;涂< /第><第style = text-align：center;  >我们< / th>< th style =  text-align：center;  > Th< / th>< th style = text-align：center;  > Fr< / th>< th style = text-align：center;  > Sa< / th>< / tr>） ; 
  int  year = DateTime.Now.Year; 
  int  month = DateTime.Now.Month; 
  int  totaldays = DateTime.DaysInMonth（年，月）; 
 
 DateTime firstDay =  new  DateTime（DateTime.Today.Year，DateTime.Today.Month， 1 ）; 
 DateTime lastDay =  new  DateTime（DateTime.Today.Year，DateTime.Today.Month，totaldays）; 
 
  int  firstdate =（ int ）firstDay.DayOfWeek; 
  int  lastdate =（ int ）lastDay.DayOfWeek; 
 
 DateTime PrelastDay =  new  DateTime（年，月， 1 ）。AddDays （-1）; 
  int  Preday = PrelastDay.Day; 
 
 DateTime NextFirstDay =  new  DateTime（年，月， 1 ）。AddMonths （ 1 ）; 
  int  Nextday = NextFirstDay.Day; 
 
  int  counter =  0 ; 
 
  for （ int  j =  0 ; j <  firstdate; j ++）
 {
  if （counter ==  0 ）
 {
 sb.Append（ < tr>）; 
} 
 sb.Append（ < td class = PrevAfterMonth < span class =code-string> > +（Preday  -  firstdate +  1 ）+  < / td>）; 
 counter + =  1 ; 
 Preday ++; 
  if （counter ==  7 ）
 {
 sb。追加（ < / tr>）; 
 counter =  0 ; 
} 
} 
 
  for （ int  i =  1 ; i <  = totaldays; i ++）
 {
  if （counter ==  0 ）
 {
 sb.Append（ < tr>）; 
} 
 
 counter + =  1 ; 
 
 DateTime todate = Convert.ToDateTime（i +   / +月+   / + year）; 
 sb.Append（ < td class = CurrentMonth  > + i +  < / TD> 中）; 
 
  if （counter ==  7 ）
 {
 sb.Append（ < / tr>）; 
 counter =  0 ; 
} 
} 
 
  if （lastdate ==  0 ）lastdate + =  6 ; 
  else   if （lastdate ==  1 ）lastdate + =  4 ; 
  else   if （lastdate ==  2 ）lastdate + =  2 ; 
  else   if （lastdate ==  3 ）lastdate =  3 ; 
  else   if （lastdate ==  4 ）lastdate  -  =  2 ; 
  else   if （lastdate ==  5 ）lastdate  -  =  4 ; 
  else   if （lastdate ==  6 ）lastdate + =  1 ; 
 
  for （ int  k =  0 ; k <  lastdate; k ++）
 {
  if （counter ==  0 ）
 {
 sb.Append（ < tr>）; 
} 
 sb.Append（ < td class = PrevAfterMonth < span class =code-string> > + Nextday +  < span class =code-string>< / td>）;

Hello,
Please use the below mention code to create calender like this:

StringBuilder sb = new StringBuilder();
                sb.Append("<table style="border: 2px solid;width:100%;"><tr><th colspan="7" style="text-align: center;height:40px;">" + DateTime.Now.ToString("Y") + "</th></tr><tr><th style="text-align: center;">Su</th><th style="text-align: center;">Mo</th><th style="text-align: center;">Tu</th><th style="text-align: center;">We</th><th style="text-align: center;">Th</th><th style="text-align: center;">Fr</th><th style="text-align: center;">Sa</th></tr>");
                int year = DateTime.Now.Year;
                int month = DateTime.Now.Month;
                int totaldays = DateTime.DaysInMonth(year, month);

                DateTime firstDay = new DateTime(DateTime.Today.Year, DateTime.Today.Month, 1);
                DateTime lastDay = new DateTime(DateTime.Today.Year, DateTime.Today.Month, totaldays);

                int firstdate = (int)firstDay.DayOfWeek;
                int lastdate = (int)lastDay.DayOfWeek;

                DateTime PrelastDay = new DateTime(year, month, 1).AddDays(-1);
                int Preday = PrelastDay.Day;

                DateTime NextFirstDay = new DateTime(year, month, 1).AddMonths(1);
                int Nextday = NextFirstDay.Day;

                int counter = 0;

                for (int j = 0; j < firstdate; j++)
                {
                    if (counter == 0)
                    {
                        sb.Append("<tr>");
                    }
                    sb.Append("<td class="PrevAfterMonth">" + (Preday - firstdate + 1) + "</td>");
                    counter += 1;
                    Preday++;
                    if (counter == 7)
                    {
                        sb.Append("</tr>");
                        counter = 0;
                    }
                }

                for (int i = 1; i <= totaldays; i++)

                    }
                }

                if (lastdate == 0) lastdate += 6;
                else if (lastdate == 1) lastdate += 4;

</table></table>
