How do I get @ajax.actionlink to work with 2 parameters?

I have an MVC application in which I am using ActionLinks like the one below to run a stored procedure in SQL Server via a Web API and display the results in a div element. The two parameters are input parameters to the stored procedure. Not to confuse, ObjType is just a regular variable name, not referring to an OOP object type.

The below ActionLink command creates this URL, which gives a 404 (not found) error. Notice that it handles the two parameters differently.
-----------------------------------------------------------------------------------
http://localhost:58641/api/ControllerName/Get/1?ObjType=Gizmo

But if I change the URL manually to this, it works and returns the desired data.
-----------------------------------------------------------------------------------
http://localhost:58641/api/ControllerName/Get?id=1&ObjType=Gizmo

Question: Searching the internet so far hasn't helped on this one.
How can I get the Ajax.ActionLink command to give me the correct URL?

What I have tried:

C#

@Ajax.ActionLink("LOCUS", "Get", "api/ControllerName", 
                  new { id = 1, ObjType = "Gizmo" },
                  AjaxOptions
	             HttpMethod = "GET",
	             UpdateTargetId = "divResult",
	             InsertionMode = InsertionMode.Replace
                })

Here:

C#

new { id = 1, ObjType = "Gizmo" }

Do something like this:

C#

new { id = 1, ObjType = "Gizmo", param1 = "value1", param2 = "value2" }

On the server side you should have a Get method with the proper parameter list...

C#

Get(string id, string ObjType, string param1, string param2)

Thanks. Actually, id and objType are the two parameters. ObjType is probably not a good choice on my part, as it looks like I'm referring to an object type, but it's just a normal parameter. The issue I'm running into is the Ajax.ActionLink handles the first parameter differently than the rest. So instead of it appending after the action with ?id=1&objType=Gizmo, it appends with instead with /1?objType-Gizmo. It treats the first parameter like it's the action name.

SOLVED

I discovered that it causes a problem if I name the first parameter 'id'. If I name it 'id' and put

new (id = 1, objType = 'Gizmo'),

then the URL comes out as

<controllername>/<actionname>/1?ObjType=Gizmo

which is not accepted by the controller action method. But if I name it anything else besides 'id' or an obvious keyword, e.g. ClientID, then the URL comes out correctly as

<controllername>/<actionname>?ClientID=1&ObjType=Gizmo
