我正在做一个 ASP.NET MVC 3 Web 服务,并且我不断地间歇性地收到这个异常。
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 Route Debugger 显示我有一些旧路由已修改或删除并且不会消失(即使在重新启动我的机器后)这一事实有关。堆栈跟踪还引用了一个早已被删除的源文件,并且我的应用程序已移动到新位置,从那时起进行了清理和重建。我错过了什么?
这是我所有的路线注册代码:
// 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 }
);
}
}
