ASP.net(c#)用類的思想實(shí)現(xiàn)插入數(shù)據(jù)到ACCESS例子

更新時(shí)間：2007年07月20日 00:00:00 作者：

昨天寫了一半,一直沒弄清楚當(dāng)ACCESS數(shù)據(jù)庫的連接代碼寫成類的時(shí)候路徑該怎么寫,搞了半天,還是用絕對(duì)路徑解決了,似乎Server.MapPath沒法在cs文件中使用.

要實(shí)現(xiàn)的功能如下:

盡量用類的思想來完成數(shù)據(jù)的插入,因?yàn)檫@個(gè)例子簡單,所以我也就不多說什么.大家自己看代碼,不懂的可以到論壇交流.

1、首先是ACCESS數(shù)據(jù)庫的設(shè)計(jì),數(shù)據(jù)庫名:myData,表名:student

字段名稱                    數(shù)據(jù)類型
sid                           自動(dòng)編號(hào)
sname                       文本
score                          數(shù)字
2、建立插入的頁面default.aspx,具體代碼如下:

<%@ Page Language="C#" Debug="true" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>無標(biāo)題頁</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:Label ID="Label1" runat="server" Text="姓名"></asp:Label>
        <asp:TextBox ID="tbxName" runat="server"></asp:TextBox><br />
        <br />
        <asp:Label ID="Label2" runat="server" Text="成績"></asp:Label>
        <asp:TextBox ID="tbxScore" runat="server"></asp:TextBox><br />
        <br />
        <asp:Button ID="btnInsert" runat="server" OnClick="btnInsert_Click" Text="插入數(shù)據(jù)" />
</div>
    </form>
</body>
</html>

3、雙擊default.aspx進(jìn)入default.aspx.cs，代碼如下:

default.aspx.cs的主要代碼如下:

using System;
using System.Data;
using System.Configuration;
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;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void btnInsert_Click(object sender, EventArgs e)
    {
        student myStu = new student();

        myStu.sname = this.tbxName.Text;
        myStu.score = Convert.ToInt32(this.tbxScore.Text);
        int i= MyClass.insertScore(myStu);
        if (i == 1)
        {
            Response.Write("插入成功");
        }
        else
        {
            Response.Write("插入失敗");
        }
    }
}

４、在App_Code建立兩個(gè)類，一個(gè)是MyClass.cs，另一個(gè)是student.cs，

MyClass.cs的主要代碼如下:

using System;
using System.Data;
using System.Configuration;
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.Data.OleDb;

/// <summary>
/// MyClass 的摘要說明
/// </summary>
public class MyClass
{

public MyClass()
{
  //
  // TODO: 在此處添加構(gòu)造函數(shù)邏輯
  //
}
    public static OleDbConnection creatCon()
    {//Data Source=后面請(qǐng)寫你自己的數(shù)據(jù)庫的絕對(duì)路徑
        return new OleDbConnection("Provider=Microsoft.Jet.OleDb.4.0;Data Source=C:/Documents and Settings/nan/My Documents/Visual Studio 2005/WebSites/WebSite3/App_Data/myData.mdb");
    }
    public static int insertScore(student myStu)
    {
            string cmdText = "insert into student(sname,score) values('" + myStu.sname + "','" + myStu.score + "')";
            OleDbConnection con = MyClass.creatCon();
            con.Open();
            OleDbCommand cmd = new OleDbCommand(cmdText, con);
            int result = Convert.ToInt32(cmd.ExecuteNonQuery());
            con.Close();
            return result;

    }
}

student.cs的主要代碼如下:

using System;
using System.Data;
using System.Configuration;
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;

/// <summary>
/// student 的摘要說明
/// </summary>
public class student
{
    public string sname;
    public int score;
}
