最近在AJAX 开发中,需要调用业务函数,操作C# Dataset,读取数据集,具体操作方法如下:
新建一 WEB 项目,创建一业务类:操作C# Dataset代码如下所示:
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;
using System.Text;
/**//// <summary>
/// test 的摘要说明
/// </summary>
public class test
{
public test()
{
//
// TODO: 在此处添加构造函数逻辑
//
}
// 数据集传递测试
[Ajax.AjaxMethod()]
public DataSet GetDataSet()
{
OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;
Data Source=D:工作项目分析 estdb.mdb;Persist Security Info=True;");
DataSet ds = new DataSet();
try
{
OleDbCommand cmd = conn.CreateCommand();
cmd.CommandText = "select * from t_name";
cmd.CommandType = CommandType.Text;
OleDbDataAdapter da = new OleDbDataAdapter(cmd);
da.Fill(ds);
return ds;
}
catch
{
conn.Close();
throw;
}
}
}创建好业务类以后,再新建一 Aspx 页面,在页面的 Page_Load 中注册业务类:
protected void Page_Load(object sender, EventArgs e)
{
Ajax.Utility.RegisterTypeForAjax(typeof(test));
}页面代码如下: <%@ Page Language="C#" AutoEventWireup="true"
CodeFile="read_dataset.aspx.cs" Inherits="read_dataset" %>
<!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>read_dataset</title>
<script language="JavaScript">
function getDataSet()
{
var ds =test.GetDataSet().value;
if(ds != null && typeof(ds) == "object" && ds.Tables != null)
{
var s = new Array();
s[s.length] = "<table style='border: #000000 1px solid; color: #993333;
font-family: 'Microsoft Sans Serif'; background-color: #ffff99;'>";
for(var i=0; i<ds.Tables[0].Rows.length; i++)
{
s[s.length] = "<tr>";
s[s.length] = "<td>" + ds.Tables[0].Rows[i].id + "</td>";
s[s.length] = "<td>" + ds.Tables[0].Rows[i].f_date + "</td>";
s[s.length] = "<td>" + ds.Tables[0].Rows[i].f_name + "</td>";
s[s.length] = "</tr>";
}
s[s.length] = "</table>";
document.getElementById("div1").innerHTML = s.join("");
}
else
{
alert("调用Ajax接口函数错误!");
}
}
</script>
</head>
<body>
<form id="form1" runat="server">
<input type="button" value="dataset" onclick="getDataSet();" />
<div id="div1">
</div>
</form>
</body>
</html>
