Saya melakukan layanan web ASP.NET MVC 3 dan saya terus mendapatkan pengecualian ini sesekali.
Jejak tumpukan:

Ini mungkin terkait dengan fakta bahwa Route Debugger menunjukkan bahwa saya memiliki beberapa rute lama yang telah saya ubah atau hapus dan tidak akan hilang (bahkan setelah me-reboot mesin saya). Pelacakan tumpukan juga mengacu pada file sumber yang telah lama dihapus dan aplikasi saya telah dipindahkan ke lokasi baru, dibersihkan dan dibangun kembali sejak saat itu. Apa yang saya lewatkan?
Ini semua kode registrasi rute saya:
// 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 }
);
}
}
