Question

我有一个Web应用程序。它有大约25-30个webforms，我在网络上将iis发布给用户。我的问题是＆＃34; a＆＃34;用户登录并使用应用程序＆＃34; b＆＃34;用户登录并突然＆＃34; a＆＃34;用户成为＆＃34; b＆＃34;用户。我怎么解决这个问题？

我尝试过会话并获得＆amp;设置用户ID的方法，但仍然在网络上更改用户。

这是登录页面，

        cn.Open();

        SqlCommand cmd = new SqlCommand("select id, sifre,aktif from Kullanici where id='" + TextBox1.Text + "' and sifre='" + TextBox2.Text + "' and aktif='1'", cn);
        SqlDataReader dr = cmd.ExecuteReader();
        string login = TextBox1.Text;
        string pwd = TextBox2.Text;
        bool bayrak = false;
        while (dr.Read())
        {
            bayrak = true;
            if ((dr["id"].ToString() == login) && (dr["sifre"].ToString() == pwd) && (dr["aktif"].ToString() == "1"))
            {
                Session["id"] = login;

                Response.Redirect("~/WebForm2.aspx");
            }

        }

这是webform2代码

        WebForm1 form1 = new WebForm1();

        kullanici = Session["id"].ToString();

        if (IsPostBack == false)
        {



            cn.Open();
            SqlCommand komutad = new SqlCommand("select ad from kullanici where id='" + kullanici + "'", cn);
            SqlCommand komutsoyad = new SqlCommand("select soyad from kullanici where id='" + kullanici + "'", cn);
            SqlCommand komutadmin = new SqlCommand("select admin from kullanici where id='" + kullanici + "'", cn);
            try{
                name = komutad.ExecuteScalar().ToString();
            surname = komutsoyad.ExecuteScalar().ToString();
            admin = komutadmin.ExecuteScalar().ToString();
            }
        catch
        {
            Response.Redirect("~/WebForm1.aspx");
        }
            DateTime tarih = DateTime.Today;

            Label1.Text = tarih.ToString().Substring(0, 10) + " --- Welcome " + name + " " + surname;
            cn.Close();

            if (admin == "0" && TreeView1.Nodes.Count == 4)
            {
                TreeView1.Nodes.RemoveAt(0);
            }
        }

name和surname成为每个用户的最后一个登录用户。
