In this article, we share the specific code of. net background page system 1 to verify whether to log in for your reference. The specific contents are as follows
First, write a new PageBase class
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 page background part code
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(' Wrong username or password! ')</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(' Wrong username or password! ')</script>");
}
}
Take the stuWishChoices page as an example and inherit the PageBase class
using System.Web.UI.WebControls.WebParts;
using System.Data.SqlClient;
using System.Collections;
namespace cbmis.ProDocumentMng
{
public partial class DocumentList : BasePage // Inheritance
{
protected void Page_Load(object sender, EventArgs e)
{
}
}
}
}
