在同一页面中有两个登录按钮

Question

在登录页面中，两个按钮用于授权用户，一个按钮用于Lecturer，另一个按钮用于学生，如何使用单个按钮执行讲师和学生使用if else语句...此项目使用C＃ASP.NET

学生

protected void log_Click(object sender, EventArgs e)
{
    Session["id"] = txtId1.Text;
    FormsAuthentication.Initialize();
    SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["connection"].ConnectionString);
    SqlCommand com = conn.CreateCommand();
    com.CommandText = "select [id], [name],[password], [rol] FROM [Student] WHERE [id] =@id AND [password]= @pass";
    com.Parameters.Add("@id", txtId1.Text);
    com.Parameters.Add("@pass", EncryptPassword(txtPass1.Text));
    conn.Open();
    SqlDataReader rd = com.ExecuteReader();

    if (rd.Read())
    {

        var _id = rd["id"].ToString();
        var _role = rd["rol"].ToString();
        var _fname = rd["name"].ToString();

        FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(

           1,
           _id,
           DateTime.Now,
           DateTime.Now.AddMonths(1),
           true,
           _role + "." + _fname,
           FormsAuthentication.FormsCookiePath);
        string hashed_ticket = FormsAuthentication.Encrypt(ticket);
        HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, hashed_ticket);

        if (ticket.IsPersistent) cookie.Expires = ticket.Expiration;

        Response.Cookies.Add(cookie);

        // Response.Redirect("~/Admin/Profile.aspx");

        if (_role == "student")
        {
            Response.Redirect("~/Student/Profile.aspx");

        }


        rd.Close();
        conn.Close();


    }

    else
    {
        lb1.Text = "Invalid username or password.";

    }
}

    {

        var _id = rd["id"].ToString();
        var _role = rd["role"].ToString();
        var _fname = rd["fname"].ToString();

        FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(

           1,
           _id,
           DateTime.Now,
           DateTime.Now.AddMonths(1),
           true,
           _role + "." + _fname,

        HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, hashed_ticket);

        if (ticket.IsPersistent) cookie.Expires = ticket.Expiration;

        Response.Cookies.Add(cookie);

        // Response.Redirect("~/Admin/Profile.aspx");

        if (_role == "Admin")

        }

        else if (_role == "Lecturer")

如何使用一个按钮执行学生和讲师登录按钮。

Answer 1

理想情况下，您需要3个表，并且只允许用户输入用户名和密码。用户通过身份验证后，将根据用户的授权角色重定向到页面。

• 用户表
• UsersInRoles表
• 角色表

然而，这不是你原来的问题。

您需要RadioButtonList或DropDownList来选择人的类型。然后根据选择更改CommandText。
