自定义IT女神节日历与农历

今天是女神节，来一篇日历显示当前日期与农历，以及显示特殊节日

一、新建窗体应用程序CustomCalendarDemo

将默认的Form1重命名为FormCustomDate，窗体FormCustomDate设计如图：

二、窗体设计器代码如下（FormCustomDate.Designer.cs）：


namespace CustomCalendarDemo
{partial class FormCustomDate{/// <summary>/// 必需的设计器变量。/// </summary>private System.ComponentModel.IContainer components = null;/// <summary>/// 清理所有正在使用的资源。/// </summary>/// <param name="disposing">如果应释放托管资源，为 true；否则为 false。</param>protected override void Dispose(bool disposing){if (disposing && (components != null)){components.Dispose();}base.Dispose(disposing);}#region Windows 窗体设计器生成的代码/// <summary>/// 设计器支持所需的方法 - 不要修改/// 使用代码编辑器修改此方法的内容。/// </summary>private void InitializeComponent(){this.cboYear = new System.Windows.Forms.ComboBox();this.cboMonth = new System.Windows.Forms.ComboBox();this.dgvDate = new System.Windows.Forms.DataGridView();this.rtbInfo = new System.Windows.Forms.RichTextBox();this.Column1 = new System.Windows.Forms.DataGridViewTextBoxColumn();this.Column2 = new System.Windows.Forms.DataGridViewTextBoxColumn();this.Column3 = new System.Windows.Forms.DataGridViewTextBoxColumn();this.Column4 = new System.Windows.Forms.DataGridViewTextBoxColumn();this.Column5 = new System.Windows.Forms.DataGridViewTextBoxColumn();this.Column6 = new System.Windows.Forms.DataGridViewTextBoxColumn();this.Column7 = new System.Windows.Forms.DataGridViewTextBoxColumn();((System.ComponentModel.ISupportInitialize)(this.dgvDate)).BeginInit();this.SuspendLayout();// // cboYear// this.cboYear.FormattingEnabled = true;this.cboYear.Location = new System.Drawing.Point(27, 12);this.cboYear.Name = "cboYear";this.cboYear.Size = new System.Drawing.Size(157, 20);this.cboYear.TabIndex = 0;this.cboYear.SelectedIndexChanged += new System.EventHandler(this.cboYear_SelectedIndexChanged);// // cboMonth// this.cboMonth.FormattingEnabled = true;this.cboMonth.Location = new System.Drawing.Point(215, 12);this.cboMonth.Name = "cboMonth";this.cboMonth.Size = new System.Drawing.Size(121, 20);this.cboMonth.TabIndex = 1;this.cboMonth.SelectedIndexChanged += new System.EventHandler(this.cboMonth_SelectedIndexChanged);// // dgvDate// this.dgvDate.AllowUserToAddRows = false;this.dgvDate.AllowUserToDeleteRows = false;this.dgvDate.ColumnHeadersHeightSizeMode = System.Windows.Forms.DataGridViewColumnHeadersHeightSizeMode.AutoSize;this.dgvDate.Columns.AddRange(new System.Windows.Forms.DataGridViewColumn[] {this.Column1,this.Column2,this.Column3,this.Column4,this.Column5,this.Column6,this.Column7});this.dgvDate.Location = new System.Drawing.Point(12, 49);this.dgvDate.Name = "dgvDate";this.dgvDate.ReadOnly = true;this.dgvDate.RowTemplate.Height = 23;this.dgvDate.Size = new System.Drawing.Size(787, 375);this.dgvDate.TabIndex = 2;this.dgvDate.CellEnter += new System.Windows.Forms.DataGridViewCellEventHandler(this.dgvDate_CellEnter);// // rtbInfo// this.rtbInfo.Location = new System.Drawing.Point(12, 439);this.rtbInfo.Name = "rtbInfo";this.rtbInfo.Size = new System.Drawing.Size(787, 239);this.rtbInfo.TabIndex = 3;this.rtbInfo.Text = "";// // Column1// this.Column1.HeaderText = "星期日";this.Column1.Name = "Column1";this.Column1.ReadOnly = true;// // Column2// this.Column2.HeaderText = "星期一";this.Column2.Name = "Column2";this.Column2.ReadOnly = true;// // Column3// this.Column3.HeaderText = "星期二";this.Column3.Name = "Column3";this.Column3.ReadOnly = true;// // Column4// this.Column4.HeaderText = "星期三";this.Column4.Name = "Column4";this.Column4.ReadOnly = true;// // Column5// this.Column5.HeaderText = "星期四";this.Column5.Name = "Column5";this.Column5.ReadOnly = true;// // Column6// this.Column6.HeaderText = "星期五";this.Column6.Name = "Column6";this.Column6.ReadOnly = true;// // Column7// this.Column7.HeaderText = "星期六";this.Column7.Name = "Column7";this.Column7.ReadOnly = true;// // FormCustomDate// this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;this.ClientSize = new System.Drawing.Size(819, 708);this.Controls.Add(this.rtbInfo);this.Controls.Add(this.dgvDate);this.Controls.Add(this.cboMonth);this.Controls.Add(this.cboYear);this.Name = "FormCustomDate";this.Text = "自制日历-显示农历";this.Load += new System.EventHandler(this.FormCustomDate_Load);((System.ComponentModel.ISupportInitialize)(this.dgvDate)).EndInit();this.ResumeLayout(false);}#endregionprivate System.Windows.Forms.ComboBox cboYear;private System.Windows.Forms.ComboBox cboMonth;private System.Windows.Forms.DataGridView dgvDate;private System.Windows.Forms.RichTextBox rtbInfo;private System.Windows.Forms.DataGridViewTextBoxColumn Column1;private System.Windows.Forms.DataGridViewTextBoxColumn Column2;private System.Windows.Forms.DataGridViewTextBoxColumn Column3;private System.Windows.Forms.DataGridViewTextBoxColumn Column4;private System.Windows.Forms.DataGridViewTextBoxColumn Column5;private System.Windows.Forms.DataGridViewTextBoxColumn Column6;private System.Windows.Forms.DataGridViewTextBoxColumn Column7;}
}

三、新建类文件ChinaDate，用于显示中国农历描述以及节日信息：

ChinaDate.cs源程序如下：

using System;
using System.Collections;
using System.Collections.Generic;
using System.Globalization;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace CustomCalendarDemo

"闰" : "";if (iMonth <= 10){strMonth += szText.Substring(iMonth - 1, 1);}else if (iMonth == 11){strMonth += "十一";}else{strMonth += "腊";}return strMonth + "月";}/// <summary>/// 获取农历日期/// </summary>/// <param name="dt"></param>/// <returns></returns>public static string GetDay(DateTime dt){int iDay = china.GetDayOfMonth(dt);string szText1 = "初十廿三";string szText2 = "一二三四五六七八九十";string strDay;if (iDay == 20){strDay = "二十";}else if (iDay == 30){strDay = "三十";}else{strDay = szText1.Substring((iDay - 1) / 10, 1);strDay = strDay + szText2.Substring((iDay - 1) % 10, 1);}return strDay;}/// <summary>/// 获取节气/// </summary>/// <param name="dt"></param>/// <returns></returns>public static string GetSolarTerm(DateTime dt){DateTime dtBase = new DateTime(1900, 1, 6, 2, 5, 0);DateTime dtNew;double num;int y;string strReturn = "";y = dt.Year;for (int i = 1; i <= 24; i++){num = 525948.76 * (y - 1900) + JQData[i - 1];dtNew = dtBase.AddMinutes(num);if (dtNew.DayOfYear == dt.DayOfYear){strReturn = JQ[i - 1];}}return strReturn;}/// <summary>/// 获取公历节日/// </summary>/// <param name="dt"></param>/// <returns></returns>public static string GetHoliday(DateTime dt){string strReturn = "";object g = gHoliday[dt.Month.ToString("00") + dt.Day.ToString("00")];if (g != null){strReturn = g.ToString();}return strReturn;}/// <summary>/// 获取农历节日/// </summary>/// <param name="dt"></param>/// <returns></returns>public static string GetChinaHoliday(DateTime dt){string strReturn = "";int year = china.GetYear(dt);int iMonth = china.GetMonth(dt);int leapMonth = china.GetLeapMonth(year);int iDay = china.GetDayOfMonth(dt);if (china.GetDayOfYear(dt) == china.GetDaysInYear(year)){strReturn = "除夕";}else if (leapMonth != iMonth){if (leapMonth != 0 && iMonth == leapMonth){iMonth--;}object n = nHoliday[iMonth.ToString("00") + iDay.ToString("00")];if (n != null){if (strReturn == ""){strReturn = n.ToString();}else{strReturn += " " + n.ToString();}}}return strReturn;}}
}

四、窗体FormCustomDate(FormCustomDate.cs)的源程序如下:

using System;

using System.ComponentModel;
