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：
