我正在做一个ASP.NET MVC3Web服务,并且我总是间歇性地得到这个异常。
堆栈跟踪:
Server Error in '/' Application.
A route named 'ListTables' is already in the route collection. Route names must be unique.

这可能与如下事实有关: Route Debugger显示我有一些已修改或删除的旧路由,并且不会消失(即使在重启我的机器之后)。堆栈跟踪也指的是一个已经被删除很久的源文件,我的应用程序已经被移动到一个新的位置,从那时起,我的应用程序被清理和重建。我遗漏了什么?
这是我所有的路线注册码:
// in Global.asax.cs:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default2", // Route name
"Api/{controller}/{action}/{id}", // URL with parameters
new { controller = "DataSource", action = "Index", area = "Api", id = UrlParameter.Optional } // Parameter defaults
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
}
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RegisterRoutes(RouteTable.Routes);
}
// in ApiAreaRegistration.cs:
public class ApiAreaRegistration : AreaRegistration
{
public override string AreaName { get { return "Api"; } }
public override void RegisterArea(AreaRegistrationContext context)
{
// DataSources
// Tables
context.MapRoute(
"ListTables",
// example:
// /api/DataSources/DataSource/1/schemata/schema/dbo/tables
"Api/DataSources/DataSource/{dataSourceId}/schemata/{schemaName}/tables",
new
{
controller = "Tables",
action = "TableList",
schemaName = "dbo",
dataSourceId = "DefaultId"
}
);
// Schemata
context.MapRoute(
"Schema",
// example:
// /api/DataSources/DataSource/1/schemata/schema/dbo
"Api/DataSources/DataSource/{dataSourceId}/schemata/{schemaName}",
new
{
controller = "Schema",
action = "Schema",
dataSourceId = "DefaultId",
schemaName = UrlParameter.Optional
}
);
// // DataSources
context.MapRoute(
"SingleDataSource",
"Api/DataSources/DataSource/{dataSourceId}",
new
{
controller = "DataSource",
action = "DataSource",
dataSourceId = UrlParameter.Optional
}
);
context.MapRoute(
"ListDataSources",
"Api/DataSources",
new
{
controller = "DataSource",
action = "DataSourceList",
dataSourceId = "DefaultId"
}
);
context.MapRoute(
"Api_default",
"Api/{controller}/{action}/{id}",
new { action = "Index", id = UrlParameter.Optional }
);
}
}

为了解决这个问题,我不得不进入我的项目的bin文件夹,删除所有的DLL文件,然后重建,这样就解决了这个问题。

这个错误可能是由多种原因造成的,我也遇到过同样的错误,并通过修改Global.asax类解决了这个问题。
Global.asax.cs的Application_Start方法类似于:
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RouteConfig.RegisterRoutes(RouteTable.Routes);
RouteConfig.RegisterRoutes(RouteTable.Routes);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
BundleConfig.RegisterBundles(BundleTable.Bundles);
}
以下代码行在此方法中出现两次:
RouteConfig.RegisterRoutes(RouteTable.Routes);
这确保了该路由被两次添加到路由列表中,同时导致错误。
我更改了Application_Start方法,如下所示,错误消失了:
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RouteConfig.RegisterRoutes(RouteTable.Routes);
AreaRegistration.RegisterAllAreas();
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
BundleConfig.RegisterBundles(BundleTable.Bundles);
}
这可能不是你的问题的答案,但也许可以在未来帮助其他人。我没有在其他人之间看到这个答案,所以我决定添加这个。

在我重命名之前,我发现Global.asax引用的是该站点的DLL文件的一个旧版本。当我做Build > Clean up时,DLL没有被清理,因为VS项目/解决方案不再引用它。似乎有时只使用较新版本的DLL,允许站点正常工作,但最终会加载这两个DLL,从而导致路由冲突。
