复制代码 代码如下:

<?xml version="1.0" encoding="utf-8" ?>
<!--overred-->
<configuration>
<configSections>
<sectiontype="URLRewriter.Config.RewriterConfigSerializerSectionHandler, URLRewriter" />
</configSections>
<RewriterConfig>
<Rules>
<RewriterRule>
<LookFor>~/d(/d+)/.aspx</LookFor>
<SendTo>~/default.aspx?id=$1</SendTo>
</RewriterRule>
</Rules>
</RewriterConfig>
<system.web>
<httpHandlers>
<add verb="*" path="*.aspx" type="URLRewriter.RewriterFactoryHandler, URLRewriter" />
</httpHandlers>
</system.web>
</configuration>

复制代码 代码如下:

namespace ActionlessForm
{
public class Form : System.Web.UI.HtmlControls.HtmlForm
{
protected override void RenderAttributes(HtmlTextWriter writer)
{
writer.WriteAttribute("name", this.Name);
base.Attributes.Remove("name");
writer.WriteAttribute("method", this.Method);
base.Attributes.Remove("method");
this.Attributes.Render(writer);
base.Attributes.Remove("action");
if (base.ID != null)
writer.WriteAttribute("id", base.ClientID);
}
}
}

复制代码 代码如下:

using System;
using System.IO;
using System.Web;
using System.Web.UI;
namespace URL
{
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)
{

}
base.WriteAttribute(name, value, encode);
}}}
