在ASP.NET MVC 5中路由可选参数

I am creating an ASP.NET MVC 5 application and I have some issues with routing. We are using the attribute Route to map our routes in the web application. I have the following action:

我正在创建一个ASP.NET MVC 5应用程序，我遇到了一些路由问题。我们使用属性Route来映射Web应用程序中的路由。我有以下行动：

[Route("{type}/{library}/{version}/{file?}/{renew?}")]
public ActionResult Index(EFileType type, 
                          string library, 
                          string version, 
                          string file = null, 
                          ECacheType renew = ECacheType.cache)
{
 // code...
}

We only can access this URL if we pass the slash char / in the end of url, like this:

如果我们在url的末尾传递斜杠char /，我们只能访问此URL，如下所示：

type/lib/version/file/cache/

It works fine but does not work without /, I get a 404 not found error, like this

它工作正常，但没有/没有工作，我得到404未找到错误，像这样

type/lib/version/file/cache

or this (without optional parameters):

或者这个（没有可选参数）：

type/lib/version

I would like to access with or without / char at the end of url. My two last parameters are optional.

我想在url的末尾使用或不使用/ char访问。我的最后两个参数是可选的。

My RouteConfig.cs is like this:

我的RouteConfig.cs是这样的：

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapMvcAttributeRoutes();
    }
}

How can I solve it? Make the slash / be optional too?

我该如何解决？斜杠/也是可选的？

Maybe you should try to have your enums as integers instead?

也许你应该尝试将你的枚举改为整数？

This is how I did it

这就是我做到的

public enum ECacheType
{
    cache=1, none=2
}

public enum EFileType 
{
    t1=1, t2=2
}

public class TestController
{
    [Route("{type}/{library}/{version}/{file?}/{renew?}")]
    public ActionResult Index2(EFileType type,
                              string library,
                              string version,
                              string file = null,
                              ECacheType renew = ECacheType.cache)
    {
        return View("Index");
    }
}

And my routing file

和我的路由文件

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

    // To enable route attribute in controllers
    routes.MapMvcAttributeRoutes();

    routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional });
}

I can then make calls like

然后我就可以打电话了

http://localhost:52392/2/lib1/ver1/file1/1
http://localhost:52392/2/lib1/ver1/file1
http://localhost:52392/2/lib1/ver1

要么

http://localhost:52392/2/lib1/ver1/file1/1/
http://localhost:52392/2/lib1/ver1/file1/
http://localhost:52392/2/lib1/ver1/

and it works fine...

它工作得很好......

//its working with mvc5
[Route("Projects/{Id}/{Title}")]
public ActionResult Index(long Id, string Title)
{
