如何将页面名称调用为folder而不是pagename.aspx

<system.webServer>
  <modules>
    <add name="UrlRewriteModule" type="System.Web.RewriteModule" />
  </modules>
</system.webServer>

<rewrite>
  <rules>
    <rule name="FolderRewrite" stopProcessing="true">
      <match url="^(.*)/$" />
      <conditions>
        <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
      </conditions>
      <action type="Rewrite" url="{R:1}.aspx" />
    </rule>
  </rules>
</rewrite>

protected void Application_Start(object sender, EventArgs e)
{
    var rules = new System.Web.Configuration.UrlRewriteSection().Rules;
    foreach (System.Web.Configuration.Rule rule in rules)
    {
        RouteTable.Routes.Add(new System.Web.Routing.Route(rule.Name, new System.Web.Routing.UrlRewriteHandler(rule.Name, rule.Action)));
    }
}
