我正在关注这篇文章以建立简单的网站。我有一个带有对象的数据库，每个对象代表 dist 上的文件和几个属性（大小、名称等），我有几个问题：

  1. 在运行我的应用程序后添加本文中的控制器（分钟 1:45）后，它不是导航到我的主页而是导航到此索引页面，并且只有在按下主页按钮后我才能看到我的主页 - 如何修复它？

  2. 在此示例中，每个人都有几个操作：删除、更新、详细信息...我只想选择Download将此文件下载到我的系统中（所有文件位置都在具有访问权限的网络文件夹中）-我该怎么做？

索引.schtml：

    ViewBag.Title = "Home Page";

当您在新控制器中编写代码并使用它来显示站点的默认主页时，您需要使用此更改文件中global.asax或RouteConfig文件中的路由（无论您在哪里注册路由），

    routes.MapRoute(
                    name: "Default",
                    url: "{controller}/{action}/{id}",
                    defaults: new { controller = "New", action = "Index", 
                                   id = UrlParameter.Optional }
                );

要下载文件，您需要一个控制器操作才能返回FileResult

public FileResult Download()
{
    byte[] fileBytes =/*fetch your file here and read it*/;
    string fileName = "example";
    return File(fileBytes, System.Net.Mime.MediaTypeNames.Application.Octet,
                  fileName);
}
