首先写一个login.ashx的一般处理程序，引用Nvelocity动态类库,在写一个数组一个list集合和一个字典集合.
放入到参数中，并且指定模版的网页。
public void ProcessRequest(HttpContext context) { context.Response.ContentType = "text/html"; Dictionary<string, string> dict = new Dictionary<string, string>(); dict["tom"] = "斯坦福"; dict ["jim"]="家里蹲"; dict["yxk"] = "北大"; string[] strs = new string[] { "路id恶化","万恶","山鸡"}; List<Person> list = new List<Person>(); list.Add(new Person { Age =30,Name ="杨中科"}); list.Add(new Person { Age =10,Name ="扬中"}); list.Add(new Person { Age =12,Name ="杨"}); VelocityEngine vltEngine = new VelocityEngine();//实例化一个velocity模版引擎 vltEngine.SetProperty(RuntimeConstants.RESOURCE_LOADER, "file"); vltEngine.SetProperty(RuntimeConstants.FILE_RESOURCE_LOADER_PATH, System.Web.Hosting.HostingEnvironment.MapPath("~/templates"));//模板文件所在的文件夹 vltEngine.Init(); VelocityContext vltContext = new VelocityContext(); vltContext.Put("ps",dict );//设置参数，在模板中可以通过$data来引用 //把person对象作为传入p vltContext.Put("mingrens",strs ); vltContext.Put("persons",list ); Template vltTemplate = vltEngine.GetTemplate("test3.htm"); System.IO.StringWriter vltWriter = new System.IO.StringWriter(); vltTemplate.Merge(vltContext, vltWriter); string html = vltWriter.GetStringBuilder().ToString();//得到html这个模板 context.Response.Write(html); }
写一个模板网页，在一个无序的列表中，#标记是nvelocity语法。
<body>
1:
<!-- $ps.tom<br />-->
<ul>
#foreach($mr in $mingrens)
<li>$mr</li>
#end
</ul>
<ul>
#foreach($p in $persons)
<li>$p.Name,$p.Age</li>
#end
</ul>
</body>
</html>
