在MVC ASP.NET中的解決方案中的兩個不同應用程序項目的不同視圖之間導航

Question

我正在進行一個項目，其中我將必須開發兩個應用程序。 我正在使用n層Artitecture，並且在解決方案中有以下項目

1. DAL
2. BLL
3. 商業實體
4. 應用1
5. 應用2

現在，我想知道如何在這兩個應用程序的視圖之間導航。通常，我們執行以下操作以在應用程序中導航

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

現在，我如何從一個應用程序的操作導航到第二個應用程序的操作。 謝謝

Answer 1

1. 我通常使用區域來處理此問題。

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

2. 如果您喜歡以這種方式添加其他項目，則可以使用Custom ViewEngine。 這樣，首先添加如下路由規則：

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

第二：添加您的應用程序的虛擬路徑：

 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;
    }

並且您要更改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，您應該在主應用程序名稱空間中實現ur控制器。 您還需要這樣解釋嗎？

如果您願意，可以開發CustomAreaViewEngine，該應用程序可以將您的應用程序放置到MyModules等自定義目錄中。

最好的選擇是將條目與兩個站點的根路徑一起放入兩個Web.Config文件中。 無論如何，您都不想要硬編碼。 然后使用它們來處理從Url.Action()獲得的字符串，您可以使用它們使用任何所需的字符串，它永遠不會檢查它們是否與您的項目實際匹配。

Web.config （其他站點的反向輸入值）：

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

碼：

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

您可能希望在每個站點等上創建一個幫助程序或單例類，以對其進行優化，但是概念保持不變。
