C# Dictionary 字典嵌套 循環遍歷

調用接口，獲取到JSon數據后轉Dictinoary，結果是字典嵌套字典，內層字典是object類型，根本沒法foreach，最后在監視里面我發現內層的數據類型是這樣的，所以我就想着把object強制轉化成Dictionary 然后再進行遍歷得到我想要的數據
以下是我的全部遍歷Demo

 

 Dictionary<String, object> dt_acount = subaccount.JsonToDic();
                                    foreach (string key in dt_acount.Keys)
                                    {
                                        //object s = dt_acount["key"];
                                        if (key.Contains("SubAccount"))
                                        {
                                            Dictionary<String, object> acount = (Dictionary<String, object>)dt_acount["SubAccount"];
                                            foreach (string item in acount.Keys)
                                            {
                                                if (item.Contains("subAccountSid"))
                                                {
                                                    model.ytx_subaccount = acount["subAccountSid"].ToString();
                                                }
                                                else if (item.Contains("subToken"))
                                                {
                                                    model.ytx_subpass = acount["subToken"].ToString();
                                                }
                                                else if (item.Contains("voipAccount"))
                                                {
                                                    model.ytx_subvoipaccount = acount["voipAccount"].ToString();
                                                }
                                                else if (item.Contains("voipPwd"))
                                                {
                                                    model.ytx_subvoippass = acount["voipPwd"].ToString();
                                                }
                                            }
                                        }
                                    }
