1.新建一个UserHelper 和 tb_User 类
public static class UserHelper ???{ ???????public static string UserShow(this HtmlHelper<tb_User> helper) ???????{ ???????????var user = helper.ViewData.Model; ???????????if (user.UserName == "dzw") ???????????{ ???????????????return string.Format("<div>我是{0}</div>", user.UserName); ???????????} ???????????else ???????????{ ???????????????return "<div>找不到</div>"; ???????????} ???????} ???}2.controller返回视图
???????public ActionResult IndexTwo() ???????{ ???????????return View(new tb_User { UserName = "dzw"}); ???????}3.页面引用UserHelper相同的命名空间
@model MvcModelApp.Models.tb_User@using MvcModelApp.Helper@{ ???Layout = null;}<!DOCTYPE html><html><head> ???<meta name="viewport" content="width=device-width" /> ???<title>IndexTwo</title></head><body> ???<div> ????????@Html.Raw(Html.UserShow()) ???</div></body></html>运行显示结果如下：
