C# 从Cookie获取对象数组

我知道如何在cookies中保存一些对象数组，并使用json将其取回，但如何从Request.cookies中以C#代码获取该数组

function onAddToBasket(id, price) {
  var items = getItems()
  items.push({ ID: id, Price: price });
  $.cookie("ubasubasket", JSON.stringify(items), { path: '/' });
}

//Getting date from cookies
function getItems() {
  var items = [];
  if ($.cookie('ubasubasket') != undefined) {
      items = JSON.parse($.cookie('ubasubasket'));
  }
  return items;
}


//C# action in controller
public void Test()
{
   var r2 = Newtonsoft.Json.JsonConvert.DeserializeObject(Request.Cookies["ubasubasket"].Value);
  /*And here i get ERROR:
  {"Unexpected character encountered while parsing value: %. Path '', line 0, position 0."} */
}

怎么样

   public void Test()
   {
       MyCookie = Request.Cookies["ubasubasket"];
       //Grab all values for single cookie into an object array.
       String[] arr2 = MyCookie.Values.AllKeys;

       //Loop through cookie Value collection and print all values.
       for (loop2 = 0; loop2 < arr2.Length; loop2++) 
       {
          Response.Write("Value" + loop2 + ": " + Server.HtmlEncode(arr2[loop2]) + "<br>");
       }
   }

公共无效测试（）
{
MyCookie=Request.Cookies[“ubasubasaket”]；
//将单个cookie的所有值捕获到对象数组中。
字符串[]arr2=mycokie.Values.AllKeys；
//循环执行cookie值集合并打印所有值。
for（loop2=0；loop2”；
}
}

结果是“Value0:”在尝试反序列化“Request.Cookies[“ubasubasaket”].Value”之前，“Request.Cookies[“ubasubasaket”].Value”的内容是什么
