                    //-------------将用户和密码保存到cookie里
                    HttpCookie bcookie = new HttpCookie("UserInfo");
                    bcookie.Values.Add("User_Name",DBClass.EncryptCookie( tbUserName.Value.Replace(" ", "")));
                    bcookie.Values.Add("User_Pwd", MD5(TextBox_Pwd.Text));
                    bcookie.Values.Add("User_Power", DBClass.EncryptCookie("0"));
                    //--------------读取要保存的时间
                    bcookie.Expires = DateTime.Now.AddDays(1);
                    Response.Cookies.Add(bcookie);

                 HttpCookie cookies = Request.Cookies["UserInfo"];
                Label1.Text = DBClass.DecryptCookie(cookies.Values["User_Name"]);

谢谢各位大侠参与 ... 愚人认为 知道 cookies 怎么用 这个问题就基本上解决了 !

直接用forms验证，你可以去看看

[itliyi]

<script language="javascript" type="text/javascript">
       function getCookies()
       {
           var cookies = document.cookie.split(";");
          for(var i=0; i<cookies.length; i++)
         {
               var cookInfo = cookies[i].split("=");
               if(cookInfo[0] == "userInfo") 
               {
                    var userInfo = cookInfo[1].split("#");
                   if(document.getElementById("txtName").value == userInfo[0])
                   {
                      document.getElementById("txtPwd").value = userInfo[1];
                     alert(userInfo[1]);
                   } 
               } 
         }
       } 
  
   </script> 
 <form id="form1" runat="server">
    <div>
        <asp:TextBox ID="txtName" runat="server"></asp:TextBox>
        <br />
        <asp:TextBox ID="txtPwd" runat="server" TextMode="Password"></asp:TextBox>
        <br />
        <asp:CheckBox ID="chkCookie" runat="server" Text="记住密码" />
        <asp:Button ID="btnLogin" runat="server" OnClick="btnLogin_Click" Text="Login" /></div>
    </form>

if (chkCookie.Checked)

    cookies.Value = txtName.Text + "#" + txtPwd.Text;
