asp.net mvc - Razor actionlink autogenerating ?length=7 in URL?

Question

I have the link below on a razor page:

@Html.ActionLink("Create New Profile", "Create", "Profile", new { @class="toplink" })

It appears in thes source of view page as shown below:

<a href="/admin/profile/create?length=7" class="toplink">Create New Profile</a>

When I click on the link the URL is like this:

http://localhost:54876/admin/profile/create?length=7

I don't want ?length=7. Why is this auto generated?

The ActionLink override you are using matches to the (string linkText, string actionName, Object routeValues, Object htmlAttributes) override. So your "Profile" value is being passed to the routeValues parameter. The behavior of this function with respect to this parameter is to take all public properties on it and add it to the list of route values used to generate the link. Since a String only has one public property (Length) you end up with "length=7".

The correct overload you want to use is the (string linkText, string actionName, string controllerName, Object routeValues, Object htmlAttributes) and you call it loke so:

@Html.ActionLink("Create New Profile", "Create", "Profile", new {}, new { @class="toplink"})
