Suppose I:
- Have a route
{controller}/{action}/{id}
in myGlobal.asax
file. - A Controller
Foo
and ActionBar(String id)
returning a view. - A very simple View containing a URL rendered by
@Url.Action("bar", "foo")
- explicitly NOT specifying anid
. - If I browse to
/foo/bar/test
, the view will show the rendered URL as/foo/bar/test
. I would have expected that it should be/foo/bar
as I didn't specify a value forid
.
Why would it include the current id even when I didn't specify it, and is there any way of 开发者_开发技巧preventing this (apart from 'hard-coding' the URL directly)?
You did specify the value for id when you put /foo/bar/test
in the browser address bar. You are essentially calling the method Bar
with the parameter "test" in your foo controller. Your simple view is irrelevant when you browse directly.
To answer your last question you may need to have a re-look at the way you are using MVC.
I believe this is a regression bug in MVC3, as discussed by Phil Haack here: http://haacked.com/archive/2011/02/20/routing-regression-with-two-consecutive-optional-url-parameters.aspx
