C# 使用C编写LoginStatus和LogoutStatus的代码#

我的登录页面控件代码为：

<table class="auto-style9">
   <tr>
       <td class="auto-style12" colspan="2" style="font-family: 
         Georgia; font-size: medium; font-weight: bold; 
         text-transform: uppercase; color: #000000">Login
       </td>
   </tr>
   <tr>
       <td class="auto-style15">User name</td>
       <td class="auto-style15">
         <asp:TextBox ID="UserNameTextBox" runat="server"></asp:TextBox>
       </td>
   </tr>
   <tr>
       <td class="auto-style15">Password </td>
       <td class="auto-style15">
         <asp:TextBox ID="PasswordTextBox" runat="server" TextMode="Password">            
         </asp:TextBox>
       </td>
   </tr>
   <tr>
       <td class="auto-style15">&nbsp;</td>
       <td class="auto-style15">
         <asp:Button ID="ButtonLogin" runat="server" 
          CommandName="Login" Text="Login!" 
          OnClick="ButtonLogin_Click" BackColor="Black" 
          ForeColor="Yellow" />
       </td>
   </tr>
 </table>

我的问题是如何制作cookie，如何在c#中为loginStatus编码，请帮助编写一些代码来实现，谢谢。

因此，基本上，您需要确定用户是否登录

您可以使用

Session

变量或

Cookie

变量

在您的

按钮登录\u单击else部分的

，成功登录后， 添加这些行

  else
  {
     LabelLoginValidity.Text = "Login Successfull!";
     Session["loggedIn"]=true;
     //or you can create cookie like this

      HttpCookie myCookie = new HttpCookie("myCookie");

      //Add key-values in the cookie
      myCookie.Values.Add("userid", objUser.id.ToString());

      //set cookie expiry date-time. Made it to last for next 30 minutes.
      myCookie.Expires = DateTime.Now.AddMinutes(30);

      //Most important, write the cookie to client.
      Response.Cookies.Add(myCookie);
  }

现在，通过这个会话或Cookie变量，您可以检查内部页面。差不多 在你的主页里

 protected void Page_load(object sender, EventArgs e)
 {
       if(Session["loggedIn"]==null)
       {
          //Session doesn't exist, redirect the user to login page
          Response.Redirect("Login.aspx");
       }
 }

您必须在注销按钮单击时销毁会话或Cookie变量，即

protected void btnLogout_Click(object sender, EventArgs e)
{
   Session.Abandon();
   //or
   //Session.Remove("loggedIn");
}

所以基本上，

Session

和

Cookie

都是状态管理技术

请不要重新发明轮子；而是使用ASP.Net的

它比编写自己的登录逻辑更安全

protected void ButtonLogin_Click(object sender, EventArgs e)
{
    using(BerouDataContext Data = new BerouDataContext())
    {
      var UsernameCheck = UserNameTextBox.Text;
      var PasswordCheck = PasswordTextBox.Text;
      var UserExist = Data.Memberships.Single(s => s.Username == UsernameCheck);
      if (UserExist == null || UserExist.Password != PasswordCheck)
      {
        LabelLoginValidity.Text = "Login Details are incorrect.";
      }
      else
      {
        FormsAuthentication.SetAuthCookie(UserNameTextBox.Text, false);
        LabelLoginValidity.Text = "Login Successfull!";
      }
   }
}
