名为“默认路由”的路由已经路线收藏。路线名称必须是唯一 [英] A route named 'DefaultRoute' is already in the route collection. Route names must be unique

问题描述

当我发布 ASP.NET的WebAPI 解决远程 IIS服务器，我得到错误信息：

  

留言信息：System.ArgumentException：名为默认路由的路由已经路线收藏。路线名称必须是唯一的。

我看了<一个href=\"http://stackoverflow.com/questions/10986909/a-route-named-x-is-already-in-the-route-collection-route-names-must-be-unique\">this同样的问题线程，但没有上工作过。我曾尝试：

1. 删除的所有项目的所有斌/ OBJ文件夹。


2. 清洁/重建


3. 删除关闭远程服务器上的文件发布前


4. 重命名项目

反正我可以找出是否有一个陈旧的文件。我做了一些重命名文件和我听说，这可能会导致一个问题？

不知道这是否重要，但我使用ASP.NET的WebAPI与RestSharp一起让我休息的电话。

这是我的的Global.asax启动有：？它是多余的。

  AreaRegistration.RegisterAllAreas（）;
WebApiConfig.Register（GlobalConfiguration.Configuration）;
RouteConfig.RegisterRoutes（RouteTable.Routes）;
 

解决方案

当我有code，明确设定使用 RouteAttribute 路线名字，我得到这个错误，当我试图建立，将取决于它是否被调用HTTP GET或HTTP POST采取不同参数的路线：

  [HTTPGET]
[路线（MyApiMethodNAME =MyApiMethod）]
公共MyApiMethod PropertyData（...）
{
    ...
}//错误：导致System.ArgumentException：名为默认路由的路由已经是路由集合的路线名称必须是唯一的。
[HttpPost]
[路线（MyApiMethodNAME =MyApiMethod）]
公共MyApiMethod PropertyData（...）
{
    ...
}
 

这是没有立即对我来说很明显，但问题原来是什么错误消息说：我有两个路径具有相同名称值。只是改变那些名称值是唯一的（无需顶部更改路线本身或方法签名）解决了该问题：

  [HTTPGET]
[路线（MyApiMethodNAME =MyApiMethod-GET）]
公共MyApiMethod PropertyData（...）
{
    ...
}[HttpPost]
[路线（MyApiMethodNAME =MyApiMethod-POST）]
公共MyApiMethod PropertyData（...）
{
    ...
}
 

When I publish an ASP.NET WebAPI solution to a remote IIS Server, I get the error message:

Message: System.ArgumentException: A route named 'DefaultRoute' is already in the route collection. Route names must be unique.

I saw this thread with the same problem, but nothing on it has worked. I have tried:

1. Deleting all bin/obj folders in all projects.
2. Cleaning/Rebuilding
3. Deleting files off the the remote server before publishing
4. Renaming the project

Is there anyway I can find out if there is a stale file. I did rename some files and I heard that this can cause a problem?

Not sure if this matters, but I am using the ASP.NET WebApi along with RestSharp to make my rest calls.

This is what my Global.asax startup has: Is it redundant?

AreaRegistration.RegisterAllAreas();
WebApiConfig.Register(GlobalConfiguration.Configuration);
RouteConfig.RegisterRoutes(RouteTable.Routes);

解决方案

I got this error when I had code that explicitly setting route names using a RouteAttribute, when I was trying to set up a route that would take different arguments depending on whether it was called with HTTP GET or HTTP POST:

[HttpGet]
[Route("MyApiMethod", Name = "MyApiMethod")]
public MyApiMethod PropertyData(...)
{
    ...
}

// ERROR: Causes "System.ArgumentException: A route named 'DefaultRoute' is already in the route collection. Route names must be unique."
[HttpPost]
[Route("MyApiMethod", Name = "MyApiMethod")]
public MyApiMethod PropertyData(...)
{
    ...
}

This wasn't immediately obvious to me, but the problem turned out to be exactly what the error message says: I had two routes with the same Name value. Just changing those Name values to be unique (without needing top change the route itself or the method signatures) fixed the issue:

[HttpGet]
[Route("MyApiMethod", Name = "MyApiMethod-GET")]
public MyApiMethod PropertyData(...)
{
    ...
}

[HttpPost]
[Route("MyApiMethod", Name = "MyApiMethod-POST")]
public MyApiMethod PropertyData(...)
{
    ...
}
