Inherits="Default2" 换成 Inherits="like" --------------------编程问答-------------------- like.aspx
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="like.aspx.cs" Inherits="like" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
你这是类名不一致造成的 --------------------编程问答-------------------- <%@ Page Language="C#" AutoEventWireup="true" CodeFile="like.aspx.cs" Inherits="Default2" %>
public class like : System.Web.UI.Page
把第一句改成
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="like.aspx.cs" Inherits="like" %>
绝对就OK了 --------------------编程问答--------------------
对，我以前也遇到过这样的问题
就是类名不一致 --------------------编程问答-------------------- 父类有没有这个方法？ --------------------编程问答--------------------
补充：.NET技术 , ASP.NET
