在MVC ASP.NET中的解决方案中的两个不同应用程序项目的不同视图之间导航

Question

我正在进行一个项目，其中我将必须开发两个应用程序。 我正在使用n层Artitecture，并且在解决方案中有以下项目

1. DAL
2. BLL
3. 商业实体
4. 应用1
5. 应用2

现在，我想知道如何在这两个应用程序的视图之间导航。通常，我们执行以下操作以在应用程序中导航

@Url.Action("ActionName", "ControllerName", OtherStuff..)

现在，我如何从一个应用程序的操作导航到第二个应用程序的操作。 谢谢

Answer 1

1. 我通常使用区域来处理此问题。

     var url = Url.Action("Index", "Home", new {Area = "Myarea"}); var url = Url.Action("Index", "Home", new {Area = "area2"}); 

2. 如果您喜欢以这种方式添加其他项目，则可以使用Custom ViewEngine。 这样，首先添加如下路由规则：

    routes.MapRoute( name: "app", url: "{application}/{controller}/{action}/{id}", defaults: new {application = "MyApplication1", controller = "Panel", action = "Index", id = UrlParameter.Optional } ); 

第二：添加您的应用程序的虚拟路径：

 public class CustomAreaViewEngine : VirtualPathProviderViewEngine
{
    public CustomAreaViewEngine()
    {
        MasterLocationFormats = new string[]
        {
            "~/Views/{1}/{0}.master",
        "~/Views/{1}/{0}.cshtml",
        "~/Views/Shared/{0}.master",
        "~/Views/Shared/{0}.cshtml",
        "~/Areas/{2}/Views/{1}/{0}.master",
        "~/Areas/{2}/Views/{1}/{0}.cshtml",
        "~/Areas/{2}/Views/Shared/{0}.master",
        "~/Areas/{2}/Views/Shared/{0}.cshtml",
        "~/Areas/{2}/{2}/Views/{1}/{0}.master",
        "~/Areas/{2}/{2}/Views/{1}/{0}.cshtml",
        "~/Areas/{2}/{2}/Views/Shared/{0}.master",
        "~/Areas/{2}/{2}/Views/Shared/{0}.cshtml",
        "~/{2}/Views/{1}/{0}.master",
        "~/{2}/Views/{1}/{0}.cshtml",
        "~/{2}/Views/Shared/{0}.master",
        "~/{2}/Views/Shared/{0}.cshtml",
        "~/{2}/{2}/Views/{1}/{0}.master",
        "~/{2}/{2}/Views/{1}/{0}.cshtml",
        "~/{2}/{2}/Views/Shared/{0}.master",
        "~/{2}/{2}/Views/Shared/{0}.cshtml",

        };
        ViewLocationFormats = new string[]
        {
        "~/Areas/{2}/Views/{1}/{0}.aspx",
        "~/Areas/{2}/Views/{1}/{0}.ascx",
        "~/Areas/{2}/Views/{1}/{0}.cshtml",
        "~/Areas/{2}/Views/Shared/{0}.aspx",
        "~/Areas/{2}/Views/Shared/{0}.ascx",
        "~/Areas/{2}/Views/Shared/{0}.cshtml",
        "~/Areas/{2}/{2}/Views/{1}/{0}.aspx",
        "~/Areas/{2}/{2}/Views/{1}/{0}.ascx",
        "~/Areas/{2}/{2}/Views/{1}/{0}.cshtml",
        "~/Areas/{2}/{2}/Views/Shared/{0}.aspx",
        "~/Areas/{2}/{2}/Views/Shared/{0}.ascx",
        "~/Areas/{2}/{2}/Views/Shared/{0}.cshtml",
        "~/{2}/Views/{1}/{0}.aspx",
        "~/{2}/Views/{1}/{0}.ascx",
        "~/{2}/Views/{1}/{0}.cshtml",
        "~/{2}/Views/Shared/{0}.aspx",
        "~/{2}/Views/Shared/{0}.ascx",
        "~/{2}/Views/Shared/{0}.cshtml",
        "~/{2}/{2}/Views/{1}/{0}.aspx",
        "~/{2}/{2}/Views/{1}/{0}.ascx",
        "~/{2}/{2}/Views/{1}/{0}.cshtml",
        "~/{2}/{2}/Views/Shared/{0}.aspx",
        "~/{2}/{2}/Views/Shared/{0}.ascx",
        "~/{2}/{2}/Views/Shared/{0}.cshtml",
        "~/Views/{1}/{0}.aspx",
        "~/Views/{1}/{0}.ascx",
        "~/Views/{1}/{0}.cshtml",
        "~/Views/Shared/{0}.aspx",
        "~/Views/Shared/{0}.ascx",
        "~/Views/Shared/{0}.cshtml"
        };
        PartialViewLocationFormats = ViewLocationFormats;
    }

并且您要更改global.asax：

 protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);

        ViewEngines.Engines.Clear();
        ViewEngines.Engines.Add(new CustomAreaViewEngine());
    }

最后，您应该在主应用程序名称空间中实现ur控制器。 您还需要这样解释吗？

如果您愿意，可以开发CustomAreaViewEngine，该应用程序可以将您的应用程序放置到MyModules等自定义目录中。

最好的选择是将条目与两个站点的根路径一起放入两个Web.Config文件中。 无论如何，您都不想要硬编码。 然后使用它们来处理从Url.Action()获得的字符串，您可以使用它们使用任何所需的字符串，它永远不会检查它们是否与您的项目实际匹配。

Web.config （其他站点的反向输入值）：

<appSettings>
    <add key="MyRoot" value="/Site1" />
    <add key="OtherRoot" value="/Site2" />
</appSettings>

码：

var myRoot = WebConfigurationManager.AppSettings["MyRoot"];
var otherRoot = WebConfigurationManager.AppSettings["OtherRoot"];
var url = Url.Action("Bla", "YadaYadaYada");
var otherUrl = otherRoot + url.Substring(myRoot.Length);

您可能希望在每个站点等上创建一个帮助程序或单例类，以对其进行优化，但是概念保持不变。
