[英]Converting a JSON.NET JObject's Properties/Tokens into Dictionary Keys
[英]Converting a Dictionary to JSON with JSON.NET
我在将dictonairy转换为JSON.NET时遇到了问题。 我确定我错过了一些观点。 此外,我使用JSON的经验很小,我主要通过php而不是c#来实现。
它增加&qout我缺少
//GENERAL NOTE: IT's a school project (so not much focus on security)
//C#
public ActionResult GetChartData(string startDate, string endDate)
{
Dictionary<Movie, double> profitList = //Gets data from repository
//in the json list i want the movie names not the objects so I make another dictonairy to convert to json
Dictionary<string, double> plist = profitList.ToDictionary(keyValuePair => keyValuePair.Key.Title, keyValuePair => keyValuePair.Value);
//Code from other stackoverflow post
//http://stackoverflow.com/questions/3739094/serializing-deserializing-dictionary-of-objects-with-json-net
string json = JsonConvert.SerializeObject(plist, Formatting.Indented, new JsonSerializerSettings
{
TypeNameHandling = TypeNameHandling.All,
TypeNameAssemblyFormat = FormatterAssemblyStyle.Simple
});
//ViewModel i Use
FinancialViewModel viewModel = new FinancialViewModel
{
ProfitList = profitList,
ProfitListJson = json,
Start = start,
End = end
};
return PartialView("_FinancialPartialView", viewModel);
}
//JS
<script>
var chart = AmCharts.makeChart("chart_6", {
"type": "pie",
"theme": "light",
"fontFamily": "Open Sans",
"color": "#888",
"dataProvider": @Model.ProfitListJson,
"valueField": "movie", //the name from the movie
"titleField": "profit", //the profit from the movie
"exportConfig": {
menuItems: [
{
icon: Metronic.getGlobalPluginsPath() + "amcharts/amcharts/images/export.png",
format: "png"
}
]
}
});
</script>
这是我想要的结果
"dataProvider": [{
"movie": "Title of movie 1",
"profit": Profit of movie 1
}, {
"movie": Title 2c",
"profit": Profit 2
}],
"valueField": "movie",
"titleField": "profit",
调试时我在控制器中得到的当前结果
铬的结果
我已经尝试了很多其他Stackoverflow的答案。 我不知道该怎么办了。
谢谢到目前为止!
为了获得具有电影和利润属性的JSON,您需要创建一个DTO(数据传输对象)Eg
public class MovieProfit
{
public string Title { get; set; }
public double Profit { get; set; }
}
然后使用Linq将您的字典转换为此DTO的列表
List<MovieProfit> plist = profitList.Select(keyValuePair => new MovieProfit() { Title = keyValuePair.Key.Title, Profit = keyValuePair.Value }).ToList();
您现在将获得序列化所需的JSON。
关于引号,这是因为您将对象序列化为JSON字符串并将字符串传递回ViewModel。 如果您将对象或对象列表传回,则不会遇到此问题。
首先,您应该删除TypeNameHandling = TypeNameHandling.All
设置。 这就是你的JSON包含$type
属性的原因。
其次,你应该使用@Html.Raw(Model.ProfitListJson)
来渲染你的JSON字符串而不是"
。
您的视图中有类似的内容:
var jsonObj = @Html.Raw(Model.ProfitListJson);
var chart = AmCharts.makeChart("chart_6", {
//...
"dataProvider": jsonObj,
//...
});
你的控制器里有这样的东西:
string json = JsonConvert.SerializeObject(plist,
Formatting.Indented,
new JsonSerializerSettings
{
TypeNameAssemblyFormat = FormatterAssemblyStyle.Simple // I don't think this is needed, but leaving it in in case you had a reason for it
});
答案应该是这样的使用jobject(newtonsoft.json.linq)
JObject o = new JObject
(
new JProperty("DataProvider",
new JArray(
from m in List
select new JObject(
new JProperty("title",m.Key),
new JProperty("profit",m.Value))))
);
这就是你可以使用o.tostring()显示
输出是这样的
{ "DataProvider": [ { "title": "movie1", "profit": 2121.0 }, { "title": "movie2", "profit": 47877.0 } ] }
