asp.net登录页面继承属性c＃

Question

i keep getting this following error:

ASPNET: Make sure that the class defined in this code file matches the 'inherits' attribute, and that it extends the correct base class (eg Page or UserControl).

it tells me the error is with the following: Login.aspx.cs Line: 1

Line 1:  using System;
Line 2:  using Entities;
Line 3:  namespace Pages.Account

here is the code for my login.aspx file

<%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Login.aspx.cs" Inherits="Pages.Account.Pages_Account_Login" %>

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
    <table>
        <tr>
            <td><b>Login: </b></td>
            <td>
                <asp:TextBox ID="txtLogin" runat="server"></asp:TextBox>
                <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" 
                    ErrorMessage="*" ControlToValidate="txtLogin"></asp:RequiredFieldValidator>
            </td>
        </tr>
        <tr>
            <td><b>Password: </b></td>
            <td>
                <asp:TextBox ID="txtPassword" runat="server" TextMode="Password"></asp:TextBox>
                <asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" 
                    ErrorMessage="*" ControlToValidate="txtPassword"></asp:RequiredFieldValidator>
            </td>
        </tr>
        <tr>
            <td>
                <asp:Button ID="btnLogin" runat="server" Text="Login" 
                    onclick="btnLogin_Click" /><br/>
                <asp:Label ID="lblError" runat="server" Text=""></asp:Label>
                <br />
                <asp:LinkButton ID="LinkButton2" runat="server" 
                    PostBackUrl="~/Pages/Account/Registration.aspx">Register</asp:LinkButton>
            </td>
        </tr>
    </table>
</asp:Content>

here is the code for my login.aspx.cs file:

using System;
using Entities;

namespace Pages.Account
{
    public partial class Pages_Account_Login : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void btnLogin_Click(object sender, EventArgs e)
        {
            User user = ConnectionClass.LoginUser(txtLogin.Text, txtPassword.Text);

            if(user != null)
            {
                //Store login variables in session
                Session["login"] = user.Name;
                Session["type"] = user.Type;

                Response.Redirect("~/Pages/Home.aspx");
            }
            else
            {
                lblError.Text = "Login failed";
            }

        }
    }
}

any help would be greatly appreciated.

Thank you.

Answer 1

I see the problem in your code; Inherits and Code Behind Class are different.

Ideally, class name should be -

public partial class Login : System.Web.UI.Page 
{
    ...
}

and Inherits should be

<%@ Page ... CodeFile="Login.aspx.cs" Inherits="Pages.Account.Login" %>

For Web Application Project, it should be CodeBehind .

<%@ Page ... CodeBehind="Login.aspx.cs" Inherits="Pages.Account.Login" %>

Answer 2

I don't see anything wrong on the surface.

When I hit the voodoo asp.net errors.

I do the following:

1. Rename MyProblemPage.aspx to MyProblemPageOLD.aspx.

2. Create a new MyProblemPage.aspx.

3. REMOVE FROM PROJECT (do not delete) MyProblemPageOLD.aspx

4. Compile. Should be no errors.

5. Move the code from aspx and .cs from MyProblemPageOLD.aspx, MyProblemPageOLD.aspx.cs

6. Compile. It should work.

7. If it compiles now, delete MyProblemPageOLD*.*

I know its not a fix, but it will get you moving again.
