Route 认为有 2 个控制器。

Question

我正在开发一个 mvc 应用程序，并且在解决路由时遇到多个控制器冲突。只有一个控制器，站点中只有一个 dll 有控制器。这是一个很大的dll，这个dll中有很多控制器。其他 MVC 路线工作正常。为什么会这样？

我知道有 2 个同名的控制器应该被命名空间。我知道拥有一个新旧 dll 都会在应用程序中加载并导致冲突，这不是问题。 - Multiple types were found that match the controller named 'Home'

The request for 'Nelson' has found the following matching controllers:
MyWebsite.Areas.Controllers.NelsonController
MyWebsite.Areas.Controllers.NelsonController

[InvalidOperationException: Multiple types were found that match the controller named 'Nelson'. This can happen if the route that services this request ('Nelson/NelsonGridView/{NelsonGVM}') does not specify namespaces to search for a controller that matches the request. If this is the case, register this route by calling an overload of the 'MapRoute' method that takes a 'namespaces' parameter.

The request for 'Nelson' has found the following matching controllers:
MyWebsite.Areas.Controllers.NelsonController
MyWebsite.Areas.Controllers.NelsonController]

//路线

context.MapRoute(
    "Nelson 603 Grid View",
    "Nelson/NelsonGridView/{NelsonGVM}",
    new { controller = this.AreaName, action = "NelsonGridView", NelsonGVM = new NelsonGVM() }
);

唯一的可能是您最终可能会在 bin 文件夹中拥有重复的 dll。你有没有机会重命名你的项目命名空间？因为这将触发 VS.NET 生成新程序集，并将旧程序集并排留在 bin 文件夹中。

请清理 bin 文件夹。重建并尝试它。
