C#输出日历

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：

[csharp] view plaincopyprint?

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：

[csharp] view plaincopyprint?

#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。
