Is it possible to pass variables from the controller to the view and create multiple different URLs? - asp.net-mvc-3

Question

I have only recently begun using MVC. I have a situation in my view where I need to create several different links to several different places. Currently I am using a switch statement using their type as a parameter, and writing them out individually. Example here:
switch (link.Type)
{
case "type1": %>
<a href='<%= Url.RouteUrl("A", new { controller = "Controller1", action = "Action1",
param1 = x, param2 = y, newWindow = "yes" }) %>' target="_blank"><%: link.Name %></a> <%
break;
case "type2": %>
<a href='<%= Url.RouteUrl("B", new { controller = "Controller2", action = "Action2",
param1 = x, param2 = y, newWindow = "yes" }) %>' target="_blank"><%: link.Name %></a> <%
break;
}
As you can see from the example above, there are only very minor changes between the URLs. I believe I will have 10-20 of these types, and obviously solution where I would only have this once on the page would be ideal.
Is it possible to pass in variables to replace "A", "Controller1", "Action1"?
EDIT1: Erik already nailed my question but out of curiosity, is it also possible to supply parameter names through variables as well? So instead of having a parameter called "param2" I could have "param2" or "param3" decided through a variable?
EDIT2:
x and y in the example are ints that the used when the Url.RouteUrl link is clicked.
So for example, I have my two parameters that are projectId and recordId in my application. When the user clicks a link they are taken to a different controller/view and proceed from there. projectId is consistent in all links, but sometimes instead of recordId it might be tableId, articleId, etc. Is there a way to deal with these different parameters?

Answer 1

MVC is a Acronym for Model, View and Controller. The Controller should more often then not, create a Model and pass it into the view:
So you might have a class like:
public class IndexViewModel
{
public string SomeString { get; set; }
public string Controller { get; set; }
public string Action { get; set; }
}
Then a controller like:
public ActionResult Index()
{
var model = new IndexViewModel();
model.SomeString = "A";
model.Controller = "Controller1";
model.Action = "Action1";
return View(model);
}
Then the view:
#model IndexViewModel
<a href='<%= Url.RouteUrl(Model.SomeString,
new { controller = Model.Controller,
action = Model.Action,
param1 = x, param2 = y, newWindow = "yes" }) %>'
target="_blank"><%: link.Name %></a>
Update 1: You can't assign a value to a class in the constructor/initializer of an anonymous class.
var myvar = new MyClass;
var myanon = new { x = 1, MyClass.Prop = 2 };
//------------------------^
// You can't do this, it doesn't make sense
Update 2: The UrlHelper.RouteUrl() Method has a number of overrides. Instead of trying to dynamically create an object for the signature RouteUrl(String, Object) use the signature RouteUrl(String, RouteValueDictionary):
model:
public class IndexViewModel
{
public string SomeString { get; set; }
public RouteValueDictionary RouteValues { get; set; }
}
controller:
public ActionResult Index()
{
var model = new IndexViewModel();
model.SomeString = "A";
model.RouteValues = new RouteValueDictionary();
model.RouteValues.Add("Controller", "Controller1");
model.RouteValues.Add("Action", "Action1");
model.RouteValues.Add("param1", x);
model.RouteValues.Add("param2", y);
return View(model);
}
view:
#model IndexViewModel
<a href='<%= Url.RouteUrl(Model.SomeString,
Model.RouteValues) %>'
target="_blank"><%: link.Name %></a>

public ActionResult Index()
{
var model = new IndexViewModel();
ViewBag.Link1="A";
ViewBag.Link2="B";
ViewBag.Link13"C";
ViewBag.Link3="D";
return View("ViewName",model);
}
Inside View
//.Link1
if(ViewBag.Link1)
{
}
if(ViewBag.Link2)
{
}
if(ViewBag.Link3)
{
}
if(ViewBag.Link4)
{
}
