用C#输出日历，此功能可用于Ajax方式列出计划日程相关的内容，由于是C#控制输出，可以方便加上自己需要的业务处理逻辑。

1.控制台输出：

using System;namespace 控制台日历{class Program{public static void Main(string[] args){string s = "    ";Console.WriteLine("输入年份：");int nYear = int.Parse(Console.ReadLine());Console.WriteLine("输入月份：");int nMonth = int.Parse(Console.ReadLine());DateTime day1 = new DateTime(nYear,nMonth,1);Console.WriteLine("{0}/{1}",day1.Year,day1.Month);Console.WriteLine("日  一  二  三  四  五  六");int week1 =(int )day1.DayOfWeek;//获取当年当月1号的星期//Console.WriteLine("当月一号的星期{0}",week1);int lastday = day1.AddMonths(1).AddDays(-1).Day; //获取当月的最后一天for (int i = 0; i < week1; i++)Console.Write(s);//不能换行输出for (int i = 1; i <= lastday; i++){Console.Write("{0:00}  ", i);//按01 02   输出if ((i + week1) % 7 == 0)Console.WriteLine();} Console.WriteLine();Console.Write("Press any key to continue . . . ");Console.ReadKey(true);}}}

效果图：

2.Html表格输出：

  #region 生成表格日历        /// <summary>        /// 生成表格日历 index：月份偏量，用来查看上一月下一月        /// </summary>        /// <param name="index"></param>        /// <returns></returns>        public static string GetCalendarHtml(int index = 0)        {            DateTime day1 = new DateTime(DateTime.Now.AddMonths(index).Year, DateTime.Now.AddMonths(index).Month, 1);            int week1 = (int)day1.DayOfWeek;//获取当年当月1号的星期             int lastday = day1.AddMonths(1).AddDays(-1).Day; //获取当月的最后一天            System.Text.StringBuilder builder = new System.Text.StringBuilder();            builder.Append(string.Format("<table class='calendar_table'><caption><span  style='cursor:pointer' class='prevMonth' onclick='javascript:changeMonth(-1)'>上一月</span><span class='currMonth'> {0}年{1}月</span><span style='cursor:pointer' class='nextMonth' onclick='javascript:changeMonth(1)'>下一月</span></caption>", DateTime.Now.AddMonths(index).Year, DateTime.Now.AddMonths(index).Month));            builder.Append("<tr class='calendar_head'>");            builder.Append("<td class='calendar_cell'>日</td>");            builder.Append("<td class='calendar_cell'>一</td>");            builder.Append("<td class='calendar_cell'>二</td>");            builder.Append("<td class='calendar_cell'>三</td>");            builder.Append("<td class='calendar_cell'>四</td>");            builder.Append("<td class='calendar_cell'>五</td>");            builder.Append("<td class='calendar_cell'>六</td>");            builder.Append("</tr>");            string emptyString = "<td class='calendar_cell'> </td>";            if (week1 > 0)            {                builder.Append("<tr class='calendar_body'>");                for (int i = 0; i < week1; i++)                {                    builder.Append(emptyString);                }            }            for (int i = 1; i <= lastday; i++)            {                string day = string.Format("{0:00}  ", i);//按01 02   输出                builder.Append(string.Format("<td class='calendar_cell'>{0}</td>", day));                if ((i + week1) % 7 == 0)                {                    builder.Append("</tr><tr class='calendar_body'>");                }            }            builder.Append("</tr>");            builder.Append("</table>");            return builder.ToString();        }        #endregion
