Asp.net Mvc Ajax Json(后阵列)

Question

JavaScript的\ jQuery的:

 var items = new Array();

 var obj { Begin: "444", End: "end" };

 items.push(obj);
 items.push(obj);

  var request = {
             DateStart: $("#DateStart").val(),
             mass: items
         };


 $.post("/Home/Index", request, null,
 "json");

C#Mvc索引控制器

 public class MyClass
     {
        public string Begin;
        public string End;
     }

     [AcceptVerbs(HttpVerbs.Post)]        
     public ActionResult Index(            
         string DateStart,            
         MyClass []mass)
     {
         System.Diagnostics.Debug.WriteLine(mass[0].Begin);
     }

如何执行此代码？谢谢.
