檢索字典在C＃.NET

Question

我有這樣

{ 
    "A" : { 
    "A1" : { 
     "er" : false, 
     "hy" : false, 
     "fv" : false, 
     "fr" : false 
      }, 
    "A2" : { 
     "fr" : false, 
     "ty" : false, 
     "ty" : false, 
      }, 
    "B" : { 
    "B1" : { 
     "er" : false, 
     "hy" : false, 
     "fv" : false, 
     "fr" : false 
     }, 
    "B2" : { 
     "fr" : false, 
     "ty" : false, 
     "ty" : false, 
    }, 
    } 
} 

一本字典我試圖找回A1和A2字典的值作爲一個單獨的字典

我已經試過

Dictionary<string, Dictionary<string, object>> dict = 
jss.Deserialize<Dictionary<string, Dictionary<string, object>>>json.ToString()); 

     Dictionary<string, object> dict1 = dict["A"]; 

Dictionary<string, object> dict2 = dict1["A1"];//error here 

不能將類型'object'隱式轉換爲'System.Collections.Generic.Dictionary'。存在明確的轉換（您是否缺少演員？）

如何解決此問題？

Answer 1

我認爲這將解決這個問題：

Dictionary<string, object> dict2 = (Dictionary<string, object>) dict1["A1"];
