asp.net mvc - Html.ActionLink (): new { route value} is acting strangely. I don't know where length = 17 parameter is coming from -

I have a link on this page

  & lt;% = html.ActionLink ( Item title, "edit", "article management," new {id = item.ArticleDataID})%>  

and a simple method to get the article ID

  edit public functioning (int id) {// something}  < / Pre> 
 Unfortunately, I'm getting an error " There is a zero value for the parameter ID of int32 to edit in the parameter dictionary ... " 
 
 When I check url, I'm looking for something like " " 
 
 " Length = 17 " What is it? And what is he doing there? Anyway, by now I am working with a collection on which there are only 3 items. 
 
 Thanks for helping 
 

To add you the tap as the last parameter Required:

  & lt;% = html.ActionLink ("title", "edit", "article management", new {id = 1}, new {@class = "link -class ", attr =" attribute value "})%>  

I think it uses root values ​​as HTML values ​​without zero.
