MVC路由問題，需要幫助插入參數

Question

我有一個表格在partialView

 @using (Html.BeginForm(null, null, new { controller = "Module", action="ModuleIndex", module="" }, FormMethod.Get, new { id = "frmMDR" })) 
     { 
      @Html.RadioButton("mdrSelector", "Maintenance", false, new { id = "rdoMaintenance" })<label for="rdoMaintenance">M</label> 
      @Html.RadioButton("mdrSelector", "Diagnostics", false, new { id = "rdoDiagnostics" })<label for="rdoDiagnostics">D</label> 
      @Html.RadioButton("mdrSelector", "Repair", false, new { id = "rdoRepair" })<label for="rdoRepair">R</label> 
      @Html.Hidden("hdnVehicle", null, new { id="hdnVehicle"}) 
     } 

當我選擇一個單選按鈕，我怎麼能填充模塊參數與所選擇的單選按鈕值？我正在使用jQuery在單選按鈕更改事件上提交表單。

$(':radio').change(function() { 

      $('#frmMDR').submit(); 
     }); 

這裏是我的控制器方法

public ActionResult ModuleIndex(string module) 
    { 

     switch (module) 
     { 
      case "Maintenance": 
       return RedirectToRoute(new { area = module, controller = "Maintenance" }); 

      case "Diagnostics": 
       return RedirectToRoute(new { area = module, controller = "Diagnostics" }); 

      case "Repair": 
       return RedirectToRoute(new { area = module, controller = "Repair" }); 

      default: 
       return RedirectToRoute(new { area = module, controller = "Maintenance" }); 

     } 

    } 

，最後這裏是我的路由配置

routes.MapRoute(
      "Module", // Route name 
      "Module/ModuleIndex/{module}", 
      new { controller = "Module", action = "ModuleIndex", module = "" } 
     ); 

什麼我不這樣做是否正確？任何提示或幫助總是表示讚賞。

據對this MSDN網站上的第一個例子，第一個字符串參數必須是相同的控制器參數名：

@Html.RadioButton("module", "Maintenance", false) 
@Html.RadioButton("module", "Diagnostics", false) 
@Html.RadioButton("module", "Repair", false)
