Razor view syntax question

The following syntax Razor View I


@ Html.ActionLink (item.Name, "Detail", "Restaurant", new {id = item.ID})

which implies the generation of the following link wrong:
http://localhost:49237/restaurant/Detail?Length=10

If I add a null parameter as follows
@ Html.ActionLink (item.Name, "Detail", "Restaurant", new {id = item.ID}, null)
the link is correct
http://localhost:49237/Restaurant/Detail/2


I want to know why you need to pass the parameter to null, and what it means
thanks

public static string ActionLink(this HtmlHelper htmlHelper,  string linkText,  string actionName,                                string controllerName, object values, object htmlAttributes)

The parameter you meant is htmlattributes where as it used to pass any HTML attribute to the action link.

Please refer: http://stackoverflow.com/questions/7329041/how-to-merge-htmlattributes-for-html-actionlink-mvc3

It calls this overload of ActionLink

By passing null value for 5th argument we make it invoke following overloaded method

I would have preferred an explanation of the behavior of the function with 4 parameters and a few more example.
