Asp.net动态页面静态化之字典哈希表的输出已及遍历判断的实现

Asp.net动态页面静态化之字典哈希表的输出已经遍历判断的实现using System;using System.Collections.Generic;using System.Linq;using System.Web;using NVelocity.Runtime;using NVelocity;using NVelocity.App;using System.Collections;namespace czbk{/// <summary>/// dictionary 的摘要说明/// </summary>public class dictionary : IHttpHandler{public void ProcessRequest(HttpContext context){context.Response.ContentType = "text/html";//新建一个带索引字典Dictionary<string, string> dict = new Dictionary<string, string>();dict["java"] = "java工程师";dict["net"] = "net工程师";dict["c"] = "c工程师";//新建hash表//DictionaryHashTable//强类型弱类型//内存小内存多//Dictionary<key,value>为HashTable的泛型版本只是 Dictionary<key,value>对存入数据类型有要求，而HashTable可以存入任何类型。Hashtable hash = new Hashtable();hash.Add("adc", "寒冰射手");hash.Add("apc", "九尾妖狐");//新建数组string[] strs = new string[] { "ef","linq","mvc","jQueery"};//新建集合List<Role> newrole=new List<Role>();newrole.Add(new Role { Roleid = "001", Rolename = "青铜" });newrole.Add(new Role { Roleid = "002", Rolename = "白银" });newrole.Add(new Role { Roleid = "003", Rolename = "黄金" });newrole.Add(new Role { Roleid = "004", Rolename = "铂金" });VelocityEngine vltEngine = new VelocityEngine();vltEngine.SetProperty(RuntimeConstants.RESOURCE_LOADER, "file");vltEngine.SetProperty(RuntimeConstants.FILE_RESOURCE_LOADER_PATH, System.Web.Hosting.HostingEnvironment.MapPath("~/"));//模板文件所在的文件夹vltEngine.Init();VelocityContext vltContext = new VelocityContext();vltContext.Put("dict", dict);//设置参数，在模板中可以通过$data来引用);vltContext.Put("hash", hash);vltContext.Put("strs", strs);vltContext.Put("newrole", newrole);Template vltTemplate = vltEngine.GetTemplate("dictionary.htm");System.IO.StringWriter vltWriter = new System.IO.StringWriter();vltTemplate.Merge(vltContext, vltWriter);string html = vltWriter.GetStringBuilder().ToString();context.Response.Write(html);}public bool IsReusable{get{return false;}}}}
