下面是全部代码，已经编译通过。
chuandi（传递）是名字空间

webform1:
<%@ page language="c#" codebehind="webform1.aspx.cs" inherits="chuandi.webform1" %>
<html>
<head>
  <title>webform1</title>
</head>
<body>
  <form id="form1" method="post" runat="server">
   <asp:textbox id="textbox1" runat="server"></asp:textbox>
   <asp:button id="button1" runat="server" text="传"></asp:button>
  </form>
</body>
</html>
using system;
namespace chuandi
{
public class webform1 : system.web.ui.page
{
  protected system.web.ui.webcontrols.textbox textbox1;
  protected system.web.ui.webcontrols.button button1;
  public string text1
  {
   get
   {
    return this.textbox1.text;
   }
  }
  private void page_load(object sender, system.eventargs e)
  {}
  override protected void oninit(eventargs e)
  {
   initializecomponent();
   base.oninit(e);
  }
  private void initializecomponent()
  {
   this.button1.click += new system.eventhandler(this.button1_click);
   this.load += new system.eventhandler(this.page_load);
  }
  private void button1_click(object sender, system.eventargs e)
  {
   server.transfer("webform2.aspx");
  }
}
}

webform2:
