ASP.NET Parser Error Cannot load code behind

Question

Hey I am getting the following error

Parser Error Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

Parser Error Message: Could not load type '_AddToCart'.

Source Error:

Line 1:  <%@ Page Language="C#" AutoEventWireup="true" Codebehind="AddToCart.aspx.cs" Inherits="_AddToCart" Title="Untitled Page" %>
Line 2:  
Line 3:  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">


Source File: /FSAICart/AddToCart.aspx    Line: 1

Where I do have the matching code behind file which is defined as follows

    using System;
  public partial class _AddToCart : System.Web.UI.Page {

Any Ideas ?

Generally its a best practice to have same name to both the class and the file.try cleaning the solution and building again. — Aravind

Try changing CodeBehind:

<%@ Page Language="C#"
AutoEventWireup="true"
**Codebehind**="AddToCart.aspx.cs"
Inherits="_AddToCart" Title="Untitled
Page" %>

To CodeFile:

<%@ Page Language="C#"
AutoEventWireup="true"
**CodeFile**="AddToCart.aspx.cs"
Inherits="_AddToCart" Title="Untitled
Page" %>

ASP .NET 1.1 used CodeBehind for compiling code in a separate file. ASP .NET 2.0 introduced the CodeFile syntax for compilation of partial classes.

See here for a more detailed explanation.

Specify the namespace of the Inherits property of Page directive

Look at codebehind of your page. It looks like:

namespace MyWebSite
{
     public partial class _AddToCart : System.Web.UI.Page 
     {
        //...
     }           
}

So you must change Page directive to:

<%@ Page Language="C#" AutoEventWireup="true" Codebehind="AddToCart.aspx.cs" Inherits="MyWebSite._AddToCart" Title="Untitled Page" %>
