Url.Action无法与使用路由注释的控制器中指定的路由一起使用

Question

I have an AdminController that looks like the following:

AdminController [Route("admin")]

Index() (landing page for all administrative content)

UserIndex() - [Route("users")]
UserDetails() - [Route("users/details/{id}")]

RoleIndex() - [Route("roles")]
RoleDetails() - [Route("roles/details/{id}")]

These equal the following URL patterns:

admin/users
admin/users/details/1

However, if I try to do the following in my view it does not work:

Url.Action("UserDetail", "Admin")

shouldn't this be smart enough to output: '/admin/users/details'?

It only works if I do Url.Action("Index", "Admin") since there is no route tag with it.

Update:

I am attempting to use Kendo Template Syntax with a Kendo Grid ClientTemplate column:

    columns.Bound(c => c.Id).ClientTemplate(
        "<a href='" +
            Url.Action("UserDetails", "Admin") +
            "/#= Id #'" +
        ">Details</a>"
    );

The link for each row ends up looking like the following: 'localhost:9000/123' The /admin/users/detail is completely being ignored...

And here is my exact declaration of the method I am trying to call in the AdminController:

// GET: Users/Details/5
[Route("users/details/{id}")]
public async Task<IActionResult> UserDetails(string id)
{
}

Recheck the routes and actions for controller

[Route("admin")]
public class AdminController : Controller {
    // GET admin
    [Route("")]
    public IActionResult Index() {...}

    //GET admin/users
    [Route("users")]
    public IActionResult UserIndex() {...}

    //GET admin/users/details/1
    [Route("users/details/{id}")]
    public IActionResult UserDetails(string id) {...}

    //GET admin/roles 
    [Route("roles")]
    public IActionResult RoleIndex() {...}

    //GET admin/roles/details/1
    [Route("roles/details/{id}")]
    public IActionResult RoleDetails(string id) {...} 

}

shouldn't this be smart enough to output: '/admin/users/details'?

according to your routes setup /admin/users/details does not exist.

Its waiting for a request to /admin/users/details/{id} where {id} is a userid . So when Url.Action("UserDetail", "Admin") is requested, there is nothing to match.

Url.Action("UserDetail", "Admin", new { id = "1" })

You can make the id parameter optional by updating the route

[Route("users/details/{id?}")]

This will allow users/details to work. but the value of id parameter will default to null .

It only works if I do Url.Action("Index", "Admin") since there is no route tag with it

It only works with Url.Action("Index", "Admin") because convention matches Index by default.
