Default.aspx代码如下:

<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<body>
    <form id="form1" runat="server">
    <div>
        <table style="font-size: 9pt">
            <tr>
                <td style="width: 61px">

            </tr>
            <tr>
                <td style="width: 61px">
                    性别:</td>
                <td style="width: 100px">
                    <asp:RadioButton ID="rbtnSex1" runat="server" Checked="True" Text="男" GroupName="Sex" />

            <tr>
                <td style="width: 61px">
                </td>

            </tr>
        </table>
    
    </div>
    </form>
</body>
</html>

Default.aspx.cs代码如下:

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class _Default : System.Web.UI.Page 
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void btnOK_Click(object sender, EventArgs e)
    {
        string name=this.txtName.Text;
        string sex="先生";
        if(rbtnSex2 .Checked)
            sex="女士";
        Response.Redirect("~/welcome.aspx?Name="+name+"&Sex="+sex);
    }
}

welcome.aspx代码如下:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="welcome.aspx.cs" Inherits="welcome" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">

<body>
    <form id="form1" runat="server">
    <div>
        &nbsp;</div>
    </form>
</body>
</html>

welcome.aspx.cs代码如下:

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class welcome : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        string name = Request.Params["Name"];
        string sex = Request.Params["Sex"];
        Response.Write("欢迎"+name+sex+"!");
    }
   
}

CodeFile改CodeBehind试试。

<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>

======>

<%@ Page Language="C#" AutoEventWireup="true"  CodeBehind="Default.aspx.cs" Inherits="_Default" %>
CodeBehind

如果还是不行,改成无codeilfe模式的,就是新建aspx页面取消勾选将代码放到单独文件中,aspx直接内嵌代码

img


<%@ Page Language="C#"  %>
<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
    }
    protected void btnOK_Click(object sender, EventArgs e)
    {
        string name=this.txtName.Text;
        string sex="先生";
        if(rbtnSex2 .Checked)
            sex="女士";
        Response.Redirect("~/welcome.aspx?Name="+name+"&Sex="+sex);
    }

vs2019按照你的代码建立aspx和cs文件没问题。之前碰到一个也是用2010开发导入别人的项目,运行没问题,但是vs就是提示无法找到控件。。不知道那里配置出问题了。。

txtName的TextBox控件相关的全部删掉,然后编译运行。没有错误后,再添加txtName的TextBox及其逻辑,然后再试。
