那么有谁能帮我解决这个问题呢

您的default.aspx页面（前端）似乎缺少所需的页面声明-这就是告诉它要使用哪个codebehind的原因

它应该位于default.aspx文件的最上面一行

默认页面声明示例：

<%@ Page Title="Home Page" Language="VB.net" MasterPageFile="~/Site.Master" 
AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebTest._Default" %>
这将告诉
ASP.net
引擎要与页面关联的文件和类名

您确定没有意外删除该行并保存文件吗

这应该很容易恢复，只需从另一个文件复制并修复
codebeahind
和
Inherits
（和
Title
）属性，使其具有正确的值

<%@ Page Title="Home Page" Language="VB.net" MasterPageFile="~/Site.Master" 
AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebTest._Default" %>

CodeBehind="Default.aspx.cs" 
Inherits="WebTest._Default"
