                };
        var Location = from d in location orderby d ascending select d;

        ViewData["Location"] = new MultiSelectList(Location);

view form code

<% using(Html.BeginForm("candidatesearch","Process",FormMethod.Post)){ %>
<%:Html.ListBox("location", ViewData["Location"] as MultiSelectList)%><br />
<input id="location" type="submit" value ="Search"/>

another action method is

    public ActionResult candidatesearch(string location )
   {
 string rg = "";
         string[] candidatelocation = location.Split(',');
                for (int i = 0; i <= candidatelocation.Length;i++ )
                {
                     rg=rg+candidatelocation[i];

                }
                Response.Write(rg);
}

but this controller get only single value i can select multiple value

Change

public ActionResult candidatesearch(string location )

To

public ActionResult candidatesearch(string[] location )

Each item in the list should be an index in the array. Instead of your split you can then do:

foreach(var item in location)
{
    //do something with item
}

Hope this helps.
