Question

这是我的查询输出：

        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

我需要为amcharts创建以下样式的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}];

我不知道如何从查询结果中排除重复的月份列，并继续将相应的行作为参数添加到同一个json对象中。我正在使用字符串构建器在我的MVC应用程序中创建一个json。任何帮助都会非常值得赞赏！

使用下面的代码，您应该每个月收集字典集，其中每个字典的键值为SARType，值为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);
