asp.net-mvc - 为什么 Response.Write 会渲染而 Html.ActionLink 不会？

Question

Asp.net Mvc1 在我的Views/home/Index.aspx上哪些路线从 http://localhost/DefectSeverityAssessmentMvcBeta/

这会渲染

  Response.Write("<a href=\"");
  Response.Write(Url.Action("Create", "Registration"));
  Response.Write("\">Begin Registration</a>");

但对于链接地址http://localhost/DefectSeverityAssessmentMvcBeta/Registration/Create返回404

虽然这不会在 View 源中渲染或显示，但不会导致任何异常:

Html.ActionLink("Begin Registration", "Create", "Registration");

我有一个 RegistrationController 和一个 /Views/Registration/Create.aspx 注册 Controller 在 Index() 和 Create() 上有断点，但它们没有被命中。

我不知道如何使用<%= %>在这种情况下，因为它位于以下代码块内:

<% if (ViewData.ContainsKey("user"))
     {
         if (ViewData.ContainsKey("registered") && (bool)ViewData["registered"] == true)
         {
             //Html.RouteLink("Resume Assessment", "Assessment", new { controller = "Assessment", action = "Index" });
             Response.Write("<a href=\"");
             // Html.ActionLink("Resume Assessment", "Index", "Assessment");

             Response.Write("\">Resume Assessment</a>");
         }
         else
         {
             //Html.RouteLink("Begin", "Registration", new { controller = "Registration", action = "Edit" });
             // Html.ActionLink("Begin Registration", "Create", "Registration");
             Html.RouteLink("Begin", "Default", new { controller = "Registration", action = "Edit" });
             //Response.Write("<a href=\"");

             //Response.Write(Url.Action("Create", "Registration"));
             //Response.Write("\">Begin Registration</a>");
         }


     }
     else
     { Response.Write("Authentication failed"); }
             %>

Answer 1

您是否在 HTML 中为 Response.Write 和 Html.ActionLink 使用 <% %>？尝试使用 <%= %> 表示 Html.ActionLink(...);

添加的等号在幕后调用 Response.Write，从而将代码写入屏幕。
