首先做一个Session验证父类，需要验证的aspx页面继承该类
Code
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>
/// IdentifyCheck 的摘要说明
/// </summary>
public class IdentifyCheck:Page
{
public IdentifyCheck()
{
}
protected override void OnLoad(EventArgs e)
{
if (Session["UserName"] == null || Session["UserName"].ToString().Trim().ToLower() != "admin")
{
//Response.Redirect(ResolveUrl("~/Manager/login.aspx"));
Response.Redirect(ResolveUrl("~/manager/login.aspx"));
}
}
}
登陆页面 login.aspx.cs
Code
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.Xml;
public partial class Manager_login : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Session["UserName"] = null;
Session["PassWord"] = null;
}
}
protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
{
if (IdentifyCheck(this.Login1.UserName, this.Login1.Password))
{
Session["UserName"] = this.Login1.UserName;
Session["PassWord"] = this.Login1.Password;
this.Response.Redirect("default.aspx");
}
}
bool IdentifyCheck(string strName, string strPass)
{
try
{
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(Server.MapPath("user.xml"));
XmlNode root = xmlDoc.SelectSingleNode("user");
XmlNodeList childList = root.ChildNodes;
foreach (XmlNode node in childList)
{
XmlNodeList childPersonLst = node.ChildNodes;
if (childPersonLst[0].InnerText.ToString() == this.Login1.UserName &&
childPersonLst[1].InnerText.ToString() == this.Login1.Password)
{
return true;
}
}
}
catch (Exception ex)
{
Response.Write(ex.Message);
return false;
}
return false;
}
}

存储帐号信息的 xml 文件
Code

其它页面.cs
Code
public partial class Manager_ModifyNews : IdentifyCheck

protected override void OnLoad(EventArgs e)
{
base.OnLoad(e); //调用base's Onload进行验证
if (!IsPostBack)
{
#region Data Bind
this.DDownClass.DataSource = NewsDAL.getAllClass();
