关于Nvelocity的主要语法和一些代码示例
context.Response.ContentType = "text/html"; VelocityEngine vltEngine = new VelocityEngine(); 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(); //匿名类 把类的定义和对象的声明初使化放到一起 var news = new { Title = "ffff", Author = "AL", PostDate = "2013-11-8", Msg = "公布消息细节" }; VelocityContext vltContext = new VelocityContext(); vltContext.Put("people", news);//设置参数,在模板中可以通过$data来引用 Template vltTemplate = vltEngine.GetTemplate("displayNews.htm"); System.IO.StringWriter vltWriter = new System.IO.StringWriter(); vltTemplate.Merge(vltContext, vltWriter); string html = vltWriter.GetStringBuilder().ToString(); context.Response.Write(html); //输出html代码
下面是Html里的模板引擎的语法写法 和C#很相似
