asp.net靜態頁面執行個體

protected void Button1_Click(object sender, EventArgs e)
{
string url = "http://" + Request.Url.Authority + "/default.aspx";
new System.Net.WebClient().DownloadFile(url, Server.MapPath("~/default.html"));
Response.Redirect("default.html");
}

這個代碼方案也是參考了很多人的代碼寫出的。在此對這些無名的奉獻者表示感謝。

貼一個核心的代碼吧：

using System;
using System.Web;
using System.Web.UI;
using System.IO;
using System.Text;
using System.Text.RegularExpressions;
using System.Configuration;

namespace BLL
{
/// <summary>
/// PageBase 的摘要說明。
/// </summary>
    public class PageBase : Page
    {
private static object obj = new object();

//// <summary>
///  重寫預設的HtmlTextWriter方法，修改form標記中的value屬性，使其值為重寫的URL而不是真實URL。
/// </summary>
/// <param name="writer"></param>
        protected override void Render(HtmlTextWriter writer)
        {
string url = Request.RawUrl.ToLower();
if (Request.RequestType.ToLower().Equals("get"))
            {
                URLRewrite u = (URLRewrite)HttpContext.Current.Items["siteurl"];
if (u != null && u.Cache > 0)
                {
string CacheFile = Server.MapPath("/Cache" + url + ".html");

                    FileUtil.CreateDirectory(CacheFile);

lock (obj)
                    {
using (StreamWriter sw = new StreamWriter(CacheFile, false, Encoding.UTF8))
                        {

base.Render(new FetchHtmlWriter(writer, sw));
                            sw.Flush();
                            sw.Close();
                            sw.Dispose();
                        }
                        Cache.Add(url, string.Empty, null, DateTime.Now.AddSeconds(u.Cache), TimeSpan.Zero, System.Web.Caching.CacheItemPriority.High, null);
return;
                    }
                }
            }
if (writer is System.Web.UI.Html32TextWriter)
            {
                writer = new FormFixerHtml32TextWriter(writer.InnerWriter);
            }
else
            {
                writer = new FormFixerHtmlTextWriter(writer.InnerWriter);
            }

base.Render(writer);
        }
    }

public class FormFixerHtml32TextWriter : System.Web.UI.Html32TextWriter
    {
public FormFixerHtml32TextWriter(TextWriter writer)
            : base(writer)
        {
        }

public override void WriteAttribute(string name, string value, bool encode)
        {
// 如果當前輸出的屬性為form標記的action屬性，則將其值替換為重寫後的虛假URL
            if (string.Compare(name, "action", true) == 0)
            {
                value = HttpContext.Current.Request.RawUrl;
            }
base.WriteAttribute(name, value, encode);
        }
    }


public class FormFixerHtmlTextWriter : System.Web.UI.HtmlTextWriter
    {
public FormFixerHtmlTextWriter(TextWriter writer)
            : base(writer)
        {
        }

public override void WriteAttribute(string name, string value, bool encode)
        {
if (string.Compare(name, "action", true) == 0)
            {
                value = HttpContext.Current.Request.RawUrl;
            }

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

有不清楚的地方，可以加QQ群：49745612一起探討。

跟前一種，產生靜態頁面的方案比，這種複雜得多，個人更喜歡前面的實現方式。
