從mailchimp campaignEmailStatsAIMAll

Question

在C＃中使用JSON我試圖程序.NET C＃代碼來讀取調用的結果campaignEmailStatsAIMAll()。

這裏是JSON結果我得到的一個樣本：

{ 
    "total":3, 
    "data":{ 
     "some...@company.com":[ 
     { 
      "action":"click", 
      "timestamp":"2012-10-18 20:55:52", 
      "url":"http:\/\/www.someurl.com?ct=t(First_Chimp_Test10_18_2012)", 
      "ip":"66.66.666.666" 
     }, 
     { 
      "action":"open", 
      "timestamp":"2012-10-18 20:55:52", 
      "url":null, 
      "ip":"66.66.666.666" 
     } 
     ], 
     "anothe...@corporation.com":[ 
     { 
      "action":"open", 
      "timestamp":"2012-10-18 20:18:05", 
      "url":null, 
      "ip":"22.222.222.222" 
     }, 
     { 
      "action":"open", 
      "timestamp":"2012-10-18 20:18:18", 
      "url":null, 
      "ip":"22.222.222.222" 
     }, 
     { 
      "action":"click", 
      "timestamp":"2012-10-18 20:18:18", 
      "url":"http:\/\/www.someurl.com?ct=t(First_Chimp_Test10_18_2012)", 
      "ip":"22.222.222.222" 
     }, 
     { 
      "action":"click", 
      "timestamp":"2012-10-18 20:21:57", 
      "url":"http:\/\/www.someurl.com?ct=t(First_Chimp_Test10_18_2012)", 
      "ip":"22.222.222.222" 
     } 
     ], 
     "thir...@business.com":[ 

     ] 
    } 
} 

我遇到的問題是如何定義的C＃對象接受這個JSON字符串。這些電子郵件地址被視爲JSON名稱/值對的名稱部分。我知道有對.NET的第三方包裝，但我只想把這個API（也許其他幾個上下行），並寧願代碼它自己。我希望能夠遍歷該對象以提取電子郵件地址，然後爲每個對象提供action/timestamp/url。

當我把這個JSON成json2sharp.com對象的創建者，我得到這個：

public class SomebodyCompanyCom {  
    public string action { get; set; }  
    public string timestamp { get; set; }  
    public string url { get; set; }  
    public string ip { get; set; } 
} 

public class AnotherpersonCorporationCom {  
    public string action { get; set; }  
    public string timestamp { get; set; }  
    public string url { get; set; }  
    public string ip { get; set; } 
} 

public class Data {  
    public List<SomebodyCompanyCom> __invalid_name__somebody@company.com { get; set; }  
    public List<AnotherpersonCorporationCom> __invalid_name__anotherperson@corporation.com { get; set; }  
    public List<object> __invalid_name__thirdguy@business.com { get; set; } 
} 

public class RootObject {  
    public int total { get; set; }  
    public Data data { get; set; } 
}

就像一臺發電機只能永遠做最好的猜測。由於JSON通常是無模式的，因此您需要分析數據並找出建模的最佳方式。

你的情況，你有兩種基本類型：

1. 由行動，時間戳，URL的各個條目和IP
2. 整體容器總和數據

一合理的模式可能是這樣的：

public class ItemInfo {  
    public string action { get; set; }  
    public string timestamp { get; set; }  
    public string url { get; set; }  
    public string ip { get; set; } 
} 

public class ContainerType { 
    public int total; 
    public Dictionary<string, ItemInfo[]> data; 
} 

如果你使用一個體面的JSON庫利柯JSON.Net，你可以反序列化JSON字符串轉換爲ContatinerType結構如下所示：

string rawJsonString = MagicallyGetTheJsonFromAWebservice(); 
ContainerType container = JsonConvert.DeserializeObject<ContainerType>(rawJsonString); 

它可能需要一些調整，以獲得反序列化類型準確的工作，但這是最基本的想法。

編輯：樣本控制檯程序做反序列化：
