利用Adapter对象将数据填充到DataTable(或DataSet)的例子
前:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="DataAdapter对象.aspx.cs" Inherits="WebApplication1.DataAdapter对象" %> <!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></title> </head> <body> <form id="form1" runat="server"> <div> <table border="1" cellpadding="0" cellspacing="0"> <tr><td>编号</td><td>账号</td><td>真实姓名</td><td>年龄</td><td> 性别</td><td>手机</td><td>电话</td><td>电子邮件</td></tr> <% ShowData(); %> </table> </div> </form> </body> </html>
后台CS代码:
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Data.SqlClient; using System.Data; namespace WebApplication1 { public partial class DataAdapter对象 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } public void ShowData() { SqlConnection connection = new SqlConnection(@"server=Rose-PC\SQLEXPRESS;Database=User;User Id=sa;password="); SqlCommand command = new SqlCommand(" Select * from UserInfo where Sex=0",connection); //conn.Open(); SqlDataAdapter adapter = new SqlDataAdapter(command); /* 下面被注释掉的代码与上面的代码是等效的 SqlDataAdapter adapter = new SqlDataAdapter("Select * from UserInfo where Sex=0",connection); */ DataTable data = new DataTable(); adapter.Fill(data); /*下面被注释掉的代码与上面的填充DataTable效果是等效的 DataSet ds=new DataSet(); adapter.Fill(ds,"UserInfo"); DataTable data=ds.Tables["UserInfo"] */ for (int i = 0; i < data.Rows.Count; i++) { Response.Write("<tr><td>"+data.Rows[i] ["ID"].ToString()+"</td>"); Response.Write("<td>" + data.Rows[i] ["UserName"].ToString() + "</td>"); Response.Write("<td>" + data.Rows[i] ["RealName"].ToString() + "</td>"); Response.Write("<td>" + data.Rows[i] ["Age"].ToString() + "</td>"); Response.Write("<td>" + (bool.Parse(data.Rows[i] ["Sex"].ToString())==true?"男":"女") + "</td>"); Response.Write("<td>" + data.Rows[i] ["Mobile"].ToString() + "</td>"); Response.Write("<td>" + data.Rows[i] ["Phone"].ToString() + "</td>"); Response.Write("<td>" + data.Rows[i] ["Email"].ToString() + "</td></tr>\n"); } } } }
