Url.Action parameters?

In listing controller I have,

 public ActionResult GetByList(string name, string contact)
 {        
     var NameCollection = Service.GetByName(name);    
     var ContactCollection = Service.GetByContact(contact);           
     return View(new ListViewModel(NameCollection ,ContactCollection));
 }

In ASPX page I call,

 <a href="<%:Url.Action("GetByList","Listing" , new {name= "John"} , new {contact="calgary, vancouver"})%>"><span>People</span></a>

I have a problem in the ASPX code... I can pull the records for the name john. but when I give the contact="calgary, vancouver", the webpage goes to error.

How can I call two parameters in the Url.Action. I tried the below but that seems wrong too.

  <a href="<%:Url.Action("GetByList","Listing" , new {name= "John" , contact= " calgary, vancouver" })%>"><span>People</span></a>

The following is the correct overload (in your example you are missing a closing } to the routeValues anonymous object so your code will throw an exception):

<a href="<%: Url.Action("GetByList", "Listing", new { name = "John", contact = "calgary, vancouver" }) %>">
    <span>People</span>
</a>

Assuming you are using the default routes this should generate the following markup:

<a href="/Listing/GetByList?name=John&amp;contact=calgary%2C%20vancouver">
    <span>People</span>
</a>

which will successfully invoke the GetByList controller action passing the two parameters:

public ActionResult GetByList(string name, string contact) 
{
    ...
}

This works for MVC 5:

<a href="@Url.Action("ActionName", "ControllerName", new { paramName1 = item.paramValue1, paramName2 = item.paramValue2 })" >
    Link text
</a>

you can returns a private collection named HttpValueCollection even the documentation says it's a NameValueCollection using the ParseQueryString utility. Then add the keys manually, HttpValueCollection do the encoding for you. And then just append the QueryString manually :

var qs = HttpUtility.ParseQueryString(""); 
qs.Add("name", "John")
qs.Add("contact", "calgary");
qs.Add("contact", "vancouver")

<a href="<%: Url.Action("GetByList", "Listing")%>?<%:qs%>">
    <span>People</span>
</a>

Here is another simple way to do it

<a class="nav-link"
   href='@Url.Action("Print1", "DeviceCertificates", new { Area = "Diagnostics"})\@Model.ID'>Print</a>

Where is @Model.ID is a parameter

And here there is a second example.

<a class="nav-link"
   href='@Url.Action("Print1", "DeviceCertificates", new { Area = "Diagnostics"})\@Model.ID?param2=ViewBag.P2&param3=ViewBag.P3'>Print</a>

You can also do the following at ASP.Net MVC

<a href="@Url.Action("GetByList", "Listing",new {area = "Admin"})'
+ @Model.Id + '?name ="John"&contact ="calgary, vancouver"'+'"'>
    <span>People</span>
</a>
