.net實現後台登入驗證

這篇文章主要為大家詳細介紹了.net後台頁面統一驗證是否登入的方法，具有一定的參考價值，感興趣的小夥伴們可以參考一下

本文執行個體為大家分享了.net後台頁面統一驗證是否登入的具體代碼，供大家參考，具體內容如下

首先新寫一個PageBase類

using System;using System.Collections.Generic;using System.Web;namespace DepartmentMIS.Web.myclass{  public class PageBase : System.Web.UI.Page  {    public PageBase()    {      this.Load += new EventHandler(BasePage_Load);    }    private void BasePage_Load(object sender, EventArgs e)    {      if (Session["UserNo"] == null || Session["UserNo"].ToString() == "")      {        Response.Redirect("~/Login.aspx");      }    }  }}

Login頁面後台部分代碼

protected void btnLogin_Click(object sender, EventArgs e)    {      if (rblRole.SelectedValue == "1")      {        DataSet ds = AdminBLL.GetList("userName = '" + tbxUserName.Text.Trim() + "' and password = '" + tbxPassword.Text.Trim()+"' and isDeleted = 0");        if (ds.Tables[0].Rows.Count == 1)        {          int id = Convert.ToInt32(ds.Tables[0].Rows[0]["id"]);          Session["UserNo"] = ds.Tables[0].Rows[0]["id"];          Session["UserName"] = ds.Tables[0].Rows[0]["userName"];          Response.Redirect("admin/adminIndex.aspx");        }        else        {          Response.Write("<script>alert('使用者名稱或密碼錯誤！')</script>");        }      }      if (rblRole.SelectedValue == "2")      {        DataSet ds = StuBLL.GetList("stuNo = '" + tbxUserName.Text.Trim() + "' and password = '" + tbxPassword.Text.Trim() + "' and isDeleted = 0");        if (ds.Tables[0].Rows.Count == 1)        {          int id = Convert.ToInt32(ds.Tables[0].Rows[0]["id"]);          Session["UserNo"] = ds.Tables[0].Rows[0]["id"];          Session["UserName"] = ds.Tables[0].Rows[0]["stuName"];          Response.Redirect("student/stusIndex.aspx");        }        else        {          Response.Write("<script>alert('使用者名稱或密碼錯誤！')</script>");        }      }

以stuWishChoices頁面為例，繼承PageBase類

using System.Web.UI.WebControls.WebParts;using System.Data.SqlClient;using System.Collections;namespace cbmis.ProDocumentMng{  public partial class DocumentList : BasePage //繼承  {      protected void Page_Load(object sender, EventArgs e)      {          }    }  }}
