现在做程序都要将动态的页面转换成静态页面,今天教大家在ASP.NET 中实现静态页面的生成方法。

using System;
  using System.Data;
  using System.Configuration;
  using System.Web;
  using System.Web.Security;
  using System.Web.UI;
  using System.Web.UI.WebControls;
  using System.Web.UI.WebControls.WebParts;
  using System.Web.UI.HtmlControls;
  using System.IO;
  using System.Text;
  ///  
  /// WriteFile 的摘要说明
  ///  
  public class WriteFile
  {
  public WriteFile()
  {
  }
  public static bool createHtml(string[] strnewsHtml,string[] stroldHtml,string strModeFilePath,string strPath)
  {
  bool flag = false;
  StreamReader sr = null;
  StreamWriter sw = null;
  string filepath = HttpContext.Current.Server.MapPath(strModeFilePath);
  Encoding code = Encoding.GetEncoding("gb2312");
  string s = string.Empty;
  try
  {
  sr = new StreamReader(filepath,code);
  s = sr.ReadToEnd();
  }
  catch (Exception ex)
  {
  throw ex;
  }
  finally
  {
  sr.Close();
  }
  try
  {
  for (int i = 0; i < strnewsHtml.Length; i  )
  {
  s = s.Replace(stroldHtml[i], strnewsHtml[i]);
  }
  sw = new StreamWriter(HttpContext.Current.Server.MapPath(strPath), false, code);
  sw.Write(s);
  flag = true;
  }
  catch (Exception ex)
  {
  flag = false;
  throw ex;
  }
  finally
  {
  sw.Flush();
  sw.Close();
  }
  return flag;
  }
  public static bool UpdateHtmlPage(string[] strNewsHtml, string[] strStartHtml, string[] strEndHtml, string strHtml)
  {
  bool Flage = false;
  StreamReader ReaderFile = null;
  StreamWriter WrirteFile = null;
  string FilePath = HttpContext.Current.Server.MapPath(strHtml);
  Encoding Code = Encoding.GetEncoding("gb2312");
  string strFile = string.Empty;
  try
  {
  ReaderFile = new StreamReader(FilePath, Code);
  strFile = ReaderFile.ReadToEnd();
  }
  catch (Exception ex)
  {
  throw ex;
  }
  finally
  {
  ReaderFile.Close();
  }
  try
  {
  int intLengTh = strNewsHtml.Length;
  for (int i = 0; i < intLengTh; i  )
  {
  int intStart = strFile.IndexOf(strStartHtml[i])   strStartHtml[i].Length;
  int intEnd = strFile.IndexOf(strEndHtml[i]);
  string strOldHtml = strFile.Substring(intStart, intEnd - intStart);
  strFile = strFile.Replace(strOldHtml, strNewsHtml[i]);
  }
  WrirteFile = new StreamWriter(FilePath, false, Code);
  WrirteFile.Write(strFile);
  Flage = true;
  }
  catch (Exception ex)
  {
  throw ex;
  }
  finally
  {
  WrirteFile.Flush();
  WrirteFile.Close();
  }
  return Flage;
  }
  }
  调用公共类:
  ----------------------------------------------------------------------------
  protected void Button2_Click(object sender, EventArgs e)
  {
  string NewsTitle = this.TextBox1.Text;
  string NewsKindName = this.DropDownList1.SelectedItem.Text;
  string NewsBody = this.WebEditor1.Text;
  DateTime PubTime = DateTime.Now;
  string UserName = Session["UserName"].ToString();
  Response.Write(NewsKindName);
  string[] strNewsHtml = new string[] { NewsTitle, NewsKindName, NewsBody, PubTime.ToString(), UserName };
  string[] strOldHtml = new string[] { "@Title", "@NewsKInd", "@NewsBody", "@PubTime", "@UserName" };
  string strFileName = DateTime.Now.ToString("ddhhmmss")   ".html";
  string strFilePath = string.Format("NewsHtml/{0}", strFileName);
  try
  {
  if (WriteFile.createHtml(strNewsHtml, strOldHtml, "mode.htm", strFilePath))
  {
  this.Label1.Text = "生成成功!";
  }
  else
  {
  this.Label1.Text = "生成失败!";
  }
  }
  catch
  {
  this.Label1.Text = "生成失败!";
  }
  }
  protected void Button3_Click(object sender, EventArgs e)
  {
  string[] strNewsHtml=new string[]{"到此一游!"};
  string[] strStartHtml=new string[]{""};
  string[] strEndHtml=new string[]{""};
  if (WriteFile.UpdateHtmlPage(strNewsHtml, strStartHtml, strEndHtml, "NewsHtml/02011139.html"))
  {
  this.Label1.Text="生成首页成功!";
  }
  else
  {
  this.Label1.Text="生成首页失败!";
  }
  }
