Answer 1

You did not show what exactly is your view's model, according to the error you got it seems you did not specify it at all (using the #model directive).
Try this
public ActionResult Index()
{
var model = (from p in am.AMS_Page_Accesses
where p.Role_id == "m"
select new linktab
{
Id = p.Id,
Link = p.Link,
Name = p.Name
}).ToList();
var abc = new linkname
{
menu = model
}
return View(abc);
}
In your view:
#model linkname
#foreach (var a in Model.menu)
{
<div>a.Name</div>
<div>a.Id</div>
<div>a.Link</div>
}

You're sending an Empty collection change you action like this,
I'm assuming that your view it's strongly typed to the List of linktab
public ActionResult Index()
{
var model = (from p in am.AMS_Page_Accesses
where p.Role_id == "m"
select new linktab{
Name = p.Name,
id = p.Id,
link = p.Link
}).ToList();
return View(model);
}
If it's not the case and your model it's strongly type to the class linkname you should do your action like this
public ActionResult Index()
{
var model = (from p in am.AMS_Page_Accesses
where p.Role_id == "m"
select new linktab{
Name = p.Name,
id = p.Id,
link = p.Link
}).ToList();
linkname abc= new linkname
{
menu = model
}
return View(abc);
}
And you may change the code in your view something like this
#foreach (var a in Model.menu)
{
<div>a.Name</div>
<div>a.Id</div>
<div>a.Link</div>
}
