It seems because you are not using proper URL format in browser while calling that action. By default, while running the application URL would be something like "http://localhost:32215/" and in this case you will get Null for id.

If we write: http://localhost:32215/Home/index/2321321
Then I am getting 2321321 as Id. (Replace "localhost:32215" with your default address)

Thanks.

Solution 2

Hello,

The id is always coming null because you may not be using properly to assign the id.

First of all the parameter you have written is int? x
The default behaviour of MVC route you have mentioned in the route is
id = UrlParameter.Optional . So you should have your parameter as id not x.

If you wish to use x, then you should access your url like:-

C#

/Home/showAll?x=123

Then you will see the value 123 when the action method debugger gets hit.
I hope you understand what I meant.
Please post back your queries if any.
Thanks

Yes you can use two or more parameters using & operator.
like /Home/Index?x=123&y=345
and the @Html.ActionLink("A name to Show","Action","Controller",new{all your parameters here})
