Json字符转化成对象

//后台  

string jsonArray = "";//此处json对象的属性必须和类库一样
  JavaScriptSerializer json = new JavaScriptSerializer();
  List<payParameter> list = new List<Reconciliation.payParameter>();
  payParameter user = json.Deserialize<payParameter>(jsonArray);

//类库

    [Serializable]
    public class payParameter
    {

　　　　    public string TotalItems { get; set; }
         　　 public SaveReconciliationDtoList[] SaveReconciliationDtoList { get; set; }

    }

    [Serializable]
    public class SaveReconciliationDtoList
    {
        public string MerCustId { get; set; }
        public string UsrCustId { get; set; }

    }
