C# 日历空间显示日志信息

2007-12-14 14:48 489 查看

今天在网上看到实现博客日志的日历的代码，把代码复制到自己的机器上运行，并在数据中插入几个数据，发现有个bug，修改一下下，小女子才学尚浅，如有错误，请大家不要见笑！

一、页面代码calTest.aspx

<%...@ Page Language="C#" AutoEventWireup="true" CodeFile="AjaxCal.aspx.cs" Inherits="test_AjaxCal" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >

<HTML>

<HEAD>

<title>WebForm1</title>

</HEAD>

<asp:calendar id="Calendar1" Width="350px" TitleStyle-BackColor="#000000" BorderColor="White"

DayHeaderStyle-BackColor="#5e715e" OtherMonthDayStyle-ForeColor="#cccccc"

runat="server" TitleStyle-ForeColor="#ffffff" NextPrevStyle-ForeColor="#ffffff"

WeekendDayStyle-BackColor="#eeeeee" DayHeaderStyle-ForeColor="#ffffff" SelectionMode="None"

TodayDayStyle-BorderColor="#5e715e" TodayDayStyle-BorderWidth="1" TodayDayStyle-Font-Bold="true"

TodayDayStyle-ForeColor="#5e715e" BackColor="White" Font-Names="Verdana" Font-Size="9pt" ForeColor="Black" Height="190px" BorderWidth="1px" NextPrevFormat="FullMonth">

</asp:calendar>

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

</form>

</body>

</HTML>

二、cs

using System;

using System.Data;

using System.Configuration;

using System.Collections;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Web.UI.HtmlControls;

using System.Threading;

using System.Globalization;

using System.Data.SqlClient;

public partial class test_AjaxCal : System.Web.UI.Page

...{

// protected System.Web.UI.WebControls.Calendar Calendar;

private int[] arrCurrentDays, arrPreDays, arrNextDays; //三个变量分别是当前月，前一月，和下一个月

private int intCurrentMonth, intPreMonth, intNextMonth; //三个整型数组存放相对月份写有blog的日期

private int intCurrentYear, intPreYear, intNextYear; //三个整型数组存放相对年份写有blog的日期（次处是我添加上来的）

protected void Page_Load(object sender, EventArgs e)

...{

TextBox1.Text = "reaer";

}

private void Calendar1_PreRender(object sender, System.EventArgs e)

...{

Thread threadCurrent = Thread.CurrentThread;

CultureInfo ciNew = (CultureInfo)threadCurrent.CurrentCulture.Clone();

ciNew.DateTimeFormat.DayNames = new string[]...{"日","一","二","三","四","五","六"};

ciNew.DateTimeFormat.FirstDayOfWeek = DayOfWeek.Sunday;

threadCurrent.CurrentCulture = ciNew;

}

private void Calendar1_DayRender(object sender, System.Web.UI.WebControls.DayRenderEventArgs e)

...{

//该控件在创建每一天时发生。

CalendarDay d = ((DayRenderEventArgs)e).Day;

TableCell c = ((DayRenderEventArgs)e).Cell;

// 初始化当前月有Blog的日期数组

if (intPreMonth == 0)

...{

//复制当前的年份前一年后一年

intCurrentYear = d.Date.Year;

intPreYear = intCurrentYear;

intNextYear = intCurrentYear;

intPreMonth = d.Date.Month; // 注意：日历控件初始化时我们得到的第一个月并不是当前月，而是前一个月的月份

intCurrentMonth = intPreMonth + 1;

if (intCurrentMonth > 12)

...{

intCurrentMonth = 1;

intCurrentYear = intCurrentYear + 1;

}

intNextMonth = intCurrentMonth + 1;

if (intNextMonth > 12)

...{

d.Date.AddYears(1);

intNextYear = intNextYear +1;

intNextMonth = 1;

}

arrPreDays = getArrayDay(intPreYear, intPreMonth); //得到前一个月有blog的日期数组

arrCurrentDays = getArrayDay(intCurrentYear, intCurrentMonth);//得到当月有blog的日期数组

arrNextDays = getArrayDay(intNextYear, intNextMonth);//得到下个月有blog的日期数组

}

int j=0;

if( d.Date.Month.Equals(intPreMonth) )

...{

while( ! arrPreDays[j].Equals(0) )

...{

if(d.Date.Day.Equals(arrPreDays[j]))

...{

c.Controls.Clear();

c.Controls.Add(new LiteralControl("<a href=WebForm1.aspx?year="+d.Date.Year+"-"+

d.Date.Month+"-"+d.Date.Day+">"+d.Date.Day+"</a>"));

}

j++;

}

else if( d.Date.Month.Equals(intCurrentMonth) )

...{

while( !arrCurrentDays[j].Equals(0) )

...{

if(d.Date.Day.Equals(arrCurrentDays[j]))

...{

c.Controls.Clear();

c.Controls.Add(new LiteralControl("<a href=WebForm1.aspx?time="+d.Date.Year+"-"+

d.Date.Month+"-"+d.Date.Day+" title='"+d.Date.Year+'/'+d.Date.Month+'/'+d.Date.Day+"'>"+d.Date.Day+"</a>"));

}

j++;

}

else if( d.Date.Month.Equals(intNextMonth) )

...{

while( ! arrNextDays[j].Equals(0) )

...{

if(d.Date.Day.Equals(arrNextDays[j]))

...{

c.Controls.Clear();

c.Controls.Add(new LiteralControl("<a href=WebForm1.aspx?year="+d.Date.Year+"-"+

d.Date.Month+"-"+d.Date.Day+">"+d.Date.Day+"</a>"));

}

j++;

}

private int[] getArrayDay(int intYear,int intMonth)

...{

int i=0;

int[] intArray = new int[31];

//从数据库里选取符合要求的记录，将日期存入数组

string mySelectQuery = "select OrderDate from test where year(OrderDate)="+intYear+

" and month(OrderDate)="+intMonth;

//SqlConnection myConnection=new SqlConnection("server=localhost;UID=sa;pwd=fan;database=test");

//SqlCommand myCommand = new SqlCommand(mySelectQuery,myConnection);

//myConnection.Open();

//SqlDataReader myReader;

//myReader = myCommand.ExecuteReader();

MySqlDB mdb=new MySqlDB(mySelectQuery);

while (!mdb.EOF)

...{

if( i==0 )

...{

intArray[i] =mdb["OrderDate"].ToDateTime().Day;

i++;

}

else if (mdb["OrderDate"].ToDateTime().Day != intArray[i - 1])

...{

intArray[i] = mdb["OrderDate"].ToDateTime().Day;

i++;

}

mdb.MoveNext();

}

return intArray;

}

网页窗体设计器生成的代码#region Web 窗体设计器生成的代码

override protected void OnInit(EventArgs e)

...{

// CODEGEN: 该调用是 ASP.NET Web 窗体设计器所必需的。

InitializeComponent();

base.OnInit(e);

}

/**//// <summary>

/// 设计器支持所需的方法 - 不要使用代码编辑器修改

/// 此方法的内容。

/// </summary>

private void InitializeComponent()

...{

this.Calendar1.DayRender += new System.Web.UI.WebControls.DayRenderEventHandler(this.Calendar1_DayRender);

this.Calendar1.PreRender += new System.EventHandler(this.Calendar1_PreRender);

this.Load += new System.EventHandler(this.Page_Load);

}

#endregion

}

三、大功告成！就可以看到漂亮的日历了

另外还有数据库不要忘记了，在数据中插入几条数据，就可以看到效果了

DROP TABLE IF EXISTS `test`.`test`;

CREATE TABLE `test`.`test` (

`OrderDate` datetime NOT NULL,

PRIMARY KEY (`OrderDate`)

) ENGINE=InnoDB DEFAULT CHARSET=latin1;

哈哈~~~如有错误，还请大侠多多指教~~~~~~~~~~~~~~~~~~~~~~~
