CS1061:编译错误消息 [英] CS1061: Compilation Error Message

问题描述

我已经在页面上添加了一个linkbutton并在调试时显示错误消息:

i have added a linkbutton to my page and get error when debugging says:

CS1061:"ASP.uilayer_test_aspx"不包含"lbl_Click"的定义，并且找不到扩展方法"lbl_Click"接受类型为"ASP.uilayer_test_aspx"的第一个参数(您是否缺少using指令或程序集参考?)

CS1061: 'ASP.uilayer_test_aspx' does not contain a definition for 'lbl_Click' and no extension method 'lbl_Click' accepting a first argument of type 'ASP.uilayer_test_aspx' could be found (are you missing a using directive or an assembly reference?)

.aspx包含:

<asp:LinkButton ID="lbl" runat="server" OnClick="lbl_Click">LinkButton</asp:LinkButton>

页面指令:

<%@ Page Language="C#" MasterPageFile="~/UILayer/UI.Master" AutoEventWireup="true" CodeBehind="Test.aspx.cs" Inherits="WebApp.UILayer.Test" Title="Untitled Page" %>

.cs包含:

namespace WebApp.UILayer
{
    public partial class Test : System.Web.UI.Page
    {
        private void lbl_Click(object sender, EventArgs e)
        {
        } 
    }
}

推荐答案

您必须使 lbl_Click 受保护而不是私有.

You have to make lbl_Click protected and not private.

这样做的原因是从aspx源创建了一个自己的类，称为 ASP.uilayer_test_aspx .该类是您的 Test 类的继承.子类不可见私有方法，因此必须对其进行保护.

The reason for this is that an own class, called like ASP.uilayer_test_aspx is created from the aspx source. This class inherits from your Test class. Private methods are not visible to child classes, so it has to be protected.
