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页面前台结合javascript实现ajax日历切换效果，只需用js改变函数中的index偏移量即可。
