Asp.Net不包含buttonClick的定义吗? [英] Asp.Net does not contain a definition for buttonClick?
问题描述
我试图在Visual Studio asp.net上构建程序，但是每当我尝试单击带有OnClick事件的按钮时，都会出现以下错误:
I am attempting to build a program on visual studio asp.net but whenever I try to click a button with an OnClick event I get the following error:
"CS1061:'ASP.test_aspx'不包含'buttonClick'的定义，并且找不到扩展方法'buttonClick'接受类型为'ASP.test_aspx'的第一个参数(您是否缺少using指令或程序集引用?)"
"CS1061: 'ASP.test_aspx' does not contain a definition for 'buttonClick' and no extension method 'buttonClick' accepting a first argument of type 'ASP.test_aspx' could be found (are you missing a using directive or an assembly reference?)"
这是我的HTML供参考:
Here is my HTML for reference:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="test.aspx.cs" Inherits="MRAApplication.test" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button id="b1" Text="Submit" runat="server" OnClick="buttonClick" />
<asp:TextBox id="txt1" runat="server" />
</div>
</form>
</body>
</html>
这是我后面的代码:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace MRAApplication
{
public partial class test : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
void buttonClick(Object sender, EventArgs e)
{
txt1.Text = "Text";
}
}
}
请保持解释尽可能简单，因为我是编码新手.感谢您提供的所有帮助. :)
Please keep explanations as simple as possible as I am new to coding. Thank you for any and all help. :)
推荐答案
您需要将事件处理程序声明为受保护的:
You need to declare your event handler as protected:
protected void buttonClick(Object sender, EventArgs e)
{
txt1.Text = "Text";
}
标记本质上是一个从后面的代码继承的类.为了使成员可以访问，必须对其进行保护或公开.
The markup is essentially a class that inherits from the code behind. In order for members to be accessible, they need to be protected or public.
