使用模板替换
public static bool WriteFile(string strText) 
  { 
  string path = HttpContext.Current.Server.MapPath("Html/"); 
  System.Text.Encoding code = System.Text.Encoding.GetEncoding("gb2312"); 
  string temp = HttpContext.Current.Server.MapPath("Html/A.html"); 
  StreamReader sr = null; 
  StreamWriter sw = null; 
  string str = ""; 
  try 
  { 
  sr = new StreamReader(temp, code); 
  str = sr.ReadToEnd(); 
  } 
  catch (Exception exp) 
  { 
  HttpContext.Current.Response.Write(exp.Message); 
  HttpContext.Current.Response.End(); 
  sr.Close(); 
  } 
  string htmlfilename = DateTime.Now.ToString("yyyyMMddHHmmss") + ".html"; 
  try 
  { 
  sw = new StreamWriter(path + htmlfilename, false, code); 
  sw.Write(str); 
  sw.Flush()
