.亲爱的开发人员:)

我正在学习ASP.NET MVC3,当我使用Response.WriteSubsitution()方法时,我陷入困境.

每当我尝试在页面中使用它时,替换文本总是出现在页面顶部(此处截图).

            ViewBag.Message = "Welcome to ASP.NET MVC!";
            return View();
        }

        [OutputCache(Duration=20)]

        {
            ViewBag.Date = DateTime.Now;
            return View();
        }
}

About.cshtml中的代码:

@using MvcApplication1;
@{
    ViewBag.Title = "About Us";
}

<h2>About</h2>
<p>
    Date : @ViewBag.Date<br />
    Random Substitued number : @{ Response.WriteSubstitution(MvcApplication1.Helpers.Test); }
</p>

我的助手课程:

namespace MvcApplication1
{
    public static class Helpers
    {
        public static string Test(HttpContext context)
        {
            Random r = new …
