我总是遇到这个错误：编译错误消息：CS0103：当前上下文中不存在名称'txtUserName'

mypage.aspx

<% @Page Language="C#" Inherits="myclass" Src="myclass.cs" %> 
<html xmlns="http://www.w3.org/1999/xhtml">

myclass.cs

using System;
using System.Data;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.IO;
using System.Net;
using System.Text;

public class myclass:Page 
{
    protected void WriteData(object sender, EventArgs e){

    string customer_id=txtUserName.Text;



    string postData="customer_id="+customer_id;

    byte[] data= Encoding.UTF8.GetBytes (postData);

    // Prepare web request...
    HttpWebRequest myRequest =
        (HttpWebRequest)WebRequest.Create("http://myserverurl.com/mypage.php");
    myRequest.Method = "POST";
    myRequest.ContentType="application/x-www-form-urlencoded";
    myRequest.ContentLength = data.Length;
    Stream newStream=myRequest.GetRequestStream();
    // Send the data.
    newStream.Write(data,0,data.Length);
    newStream.Close();
    }
}

这里有任何帮助吗？

谢谢，

尝试将类声明更改为“public partial class myclass：System.Web.UI.Page”。我认为，partial关键字对于编译器来说至关重要，因为他们知道类定义的平衡是在临时/中间文件中创建的，否则就不会知道。
