如何創建帶有重複列值

Question

JSON對象這是我的查詢輸出：

 Month SARType Count 
     --------------------------- 
     April Data Protection Breach 2 
     April Miscellaneous - Employee Matters/Fraud 1 
     April Miscellaneous - Information Security 2 
     April Miscellaneous - Unusual Calls/Correspondence 1 
     April Theft - Damage/Theft/Lost Company Property 1 
     March Code of Conduct - Disclosure of Password 1 
     March Data Protection Breach 2 
     March Information Security - Phishing/Spear Phishing 1 
     March Miscellaneous - Employee Matters/Fraud 2 
     March Miscellaneous - Information Security 10 
     March Miscellaneous - Unusual Calls/Correspondence 5 

我需要創建amcharts在下面的風格JSON：

var chartData = [{ 
    month: "April", 
    Data Protection Breach: 2, 
    Miscellaneous - Employee Matters/Fraud: 1, 
    Miscellaneous - Information Security: 2, 
    Miscellaneous - Unusual Calls/Correspondence: 1}, 
    { 
    month: "March", 
    Data Protection Breach: 2, 
    Miscellaneous - Employee Matters/Fraud: 1, 
    Miscellaneous - Information Security: 2, 
    Miscellaneous - Unusual Calls/Correspondence: 1}]; 

我不知道如何從查詢結果中排除重複的月份列，並繼續將相應的行作爲參數添加到同一個json對象。我正在使用字符串生成器在我的MVC應用程序中創建一個json。任何幫助將非常可觀！

有了下面的代碼，你應該得到的字典集合每月，每一個地方都有字典鍵作爲的SARType值和值由`Month`然後創建字典/名稱值Count

var data = 
    yourDataTable.AsEnumerable() 
       .GroupBy(row => row.Field<string>("Month")) 
       .Select(group => 
       { 
        var temp = new Dictionary<string, object> 
        { 
         { "month", group.Key } 
        } 

        foreach(var row in group) 
        { 
         temp.Add(row.Field<string>("SARType"), row.Field<int>("Count")); 
        } 

        return temp; 
       }); 

serializedData = Newtonsoft.Json.JsonConvert.SerializeObject(data);
