.net 中URL 重写post提交后的地址变为了原地址问题的解决

.net 中URL 重写post提交后的地址变为了原地址
让Page类继承OLPage 类就可以了，如：public partial class Bottom : gcy.Utility.OLPage
 {
 protected void Page_Load(object sender, EventArgs e)
 { }
 }-----------------------------------------------------------------------
gcy.Utility namespace :using System;
using System.IO;
using System.Web;
using System.Web.UI;
namespace gcy.Utility
{
 public class OLPage : Page
 {
 public OLPage()
 {

 }
 protected override void Render(HtmlTextWriter writer)
 {
 if (writer is System.Web.UI.Html32TextWriter)
 {
 writer = new FormFixerHtml32TextWriter(writer.InnerWriter);
 }
 else
 {
 writer = new FormFixerHtmlTextWriter(writer.InnerWriter);
 }
 base.Render(writer);
 }
 } internal class FormFixerHtml32TextWriter : System.Web.UI.Html32TextWriter
 {
 private string _url; // 假的URL
 internal FormFixerHtml32TextWriter(TextWriter writer):base(writer)
 {
 _url = HttpContext.Current.Request.RawUrl;
 }
 public override void WriteAttribute(string name,string value,bool encode)
 {
 if (_url != null && string.Compare(name,"action",true) == 0)
 {
 value = _url;
 }
 base.WriteAttribute(name,value,encode);
 }
 }
 internal class FormFixerHtmlTextWriter : System.Web.UI.HtmlTextWriter
 {
 private string _url;
 internal FormFixerHtmlTextWriter(TextWriter writer):base(writer)
 {
 _url = HttpContext.Current.Request.RawUrl;
 }
 public override void WriteAttribute(string name,string value,bool encode)
 {
 if (_url != null && string.Compare(name,"action",true) == 0)
 {
 value = _url;
 }
 base.WriteAttribute(name,value,encode);
 }
 }}
