在mvc4此对象定义无参数的构造函数

using Michell.ClaimsAuditAdmin.Models; 
using Mitchell.ClaimsAuditAdmin.Repositories; 
using Mitchell.ClaimsAuditAdmin.Web.Models; 
using System.Web.Mvc; 

namespace Mitchell.ClaimsAuditAdmin.Web.Controllers 
{ 
    public class ClaimAuditAdminController : Controller 
    { 
     private readonly IClaimsAuditAdminRepository claimAuditAdminRepository; 


     public ClaimAuditAdminController(IClaimsAuditAdminRepository claimAuditAdminRepository) 
     { 
      this.claimAuditAdminRepository = claimAuditAdminRepository; 
     } 

     public ActionResult Index() 
     { 
      return View("SearchResultTest"); 
     } 

     public ActionResult TestView() 
     { 
      return View("TestView"); 
     } 


     public ViewResult DisplayClaimAuditView() 
     { 
      return View("_ClaimAuditAdminView"); 
     } 

     public ActionResult SearchResultTest() 
     { 
      return View(); 
     } 

     public ActionResult ClaimAuditReviewFilter() 
     { 
      //ClaimAuditModel objClaimAudit = new ClaimAuditModel(); 
      //objClaimAudit.ClaimAudit_ID = 1; 
      //objClaimAudit.ClaimAudit_Name = "Claim1"; 
      //objClaimAudit.FromDate = DateTime.Now.AddYears(-1); 
      //objClaimAudit.FromDate = DateTime.Now; 
      return PartialView("_ClaimAuditAdminView"); 
     } 



    } 
}

我知道这个问题已经被问了很多次，但阅读这些SO类似的问题后，我不能够追踪我的error.I已经把调试器在我的控制器构造函数（ClaimAuditAdminController）但调试器不会去那里。我Route.Config是在mvc4此对象定义无参数的构造函数

public class RouteConfig 
    { 
     public static void RegisterRoutes(RouteCollection routes) 
     { 
      routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); 

      routes.MapRoute(
       name: "Default", 
       url: "{controller}/{action}/{id}", 
       defaults: new { controller = "ClaimAuditAdmin", action = "DisplayClaimAuditView", id = UrlParameter.Optional } 
      ); 
     }

和我的错误的屏幕截图是

激活试图建立与乌尔构造parametrless控制器。但是虽然您的控制器构造函数具有参数

public ClaimAuditAdminController(IClaimsAuditAdminRepository claimAuditAdminRepository) <--this place 
    { 
     this.claimAuditAdminRepository = claimAuditAdminRepository; 
    }

发生异常。尝试从构造函数中删除param或尝试覆盖DefaultControllerFactory 并使用参数创建控制器。
