序列化列表进入谷歌图表 json 数据表
我正在寻找一种将对象列表序列化为 google 图表 json 数据格式的通用方法。
此示例非常接近,但它使用数据表..
我希望这会涉及一些反射以及模型属性上的一些属性。 谁能指点我去图书馆之类的地方吗?
如果我可以将这样的查询序列化为谷歌图表格式,那就更好了:
var results = from m in be.cmsMember
where m.FirstLogin != null
&& m.FirstLogin >= BitCoinGoLive
group m by
new { Year = m.FirstLogin.Value.Year, Month = m.FirstLogin.Value.Month, Day = m.FirstLogin.Value.Day } into grp
select new
{
Year = grp.Key.Year,
Month = grp.Key.Month,
Day = grp.Key.Day,
Count = grp.Count()
};
I'm looking for a generic way of serializing a List of objects into the google charts json data format.
This example is quite close, but it's using a datatable..
I expect this would involve some reflection and some maybe attrbutes on the model properties.
Can anyone point me to a library or something?
Even better would be if I could serialize a query like this into the google charts format:
var results = from m in be.cmsMember
where m.FirstLogin != null
&& m.FirstLogin >= BitCoinGoLive
group m by
new { Year = m.FirstLogin.Value.Year, Month = m.FirstLogin.Value.Month, Day = m.FirstLogin.Value.Day } into grp
select new
{
Year = grp.Key.Year,
Month = grp.Key.Month,
Day = grp.Key.Day,
Count = grp.Count()
};

我将创建自己的与 Google API 相匹配的类层次结构,然后使用 JSON.NET 对其进行序列化。可能的数据模型:
然后是一个示例用法:
您可以使用 Linq 的 Select() 将数据转换为 Google 的数据模型,然后将其序列化为 JSON。
I would create my own class hierarchy that matches Google's API and then use JSON.NET to serialize it. The possible data model:
Then an example usage:
You can use Linq's Select() to transform your data into Google's data model, then serialize it to JSON.
这是一个完整的工作函数,也适用于匿名类型。
但要小心日期:这些也需要在客户端上解析:例如
Here's a full working funciton which also works with anonymous types.
Carefull with dates though: these need to parsed on the client as well:e.g.
查看 JSON.NET。这是一个很棒的库,可以根据您的类生成 json,此页面将为您提供如何序列化的示例: http://james.newtonking.com/pages/json-net.aspx。
希望这能为您指明正确的方向,
Have a look at JSON.NET. It's a great library to generate json based on your class, this page will give you examples of how to serialise : http://james.newtonking.com/pages/json-net.aspx.
Hopefully this will point you in the right direction,
我建议使用与 google 图表 JSON 格式相匹配的类组合,并结合 Json.net。基本步骤是。
这是 @emfurry 和 @TWith2Sugars 的两个建议的组合。
因此,使用类似于@emfurrys的类(也许添加一些构造函数来消除对对象初始化程序的需要)有点像:
bob是你的叔叔。注意 Bob 未经测试,他在这里只是作为一个小例子,他做了一些假设,但他希望给出如何快速从任何数据源到 Google 图表 JSON 格式的概述。
I recommend using a combination of classes matching google's JSON format for the charts, combined with Json.net. Essential steps are.
This is a combination of the two suggestions by @emfurry and @TWith2Sugars.
So with classes similar to @emfurrys in place (maybe add some constructors to remove need for object initialiser) Something a bit like :
bob's your uncle. N.B Bob is untested, he's here just as a little example, he assumes a fair bit, but he hopefully gives the outline of how to go quickly from any data source to Google's chart JSON format.
我使用 Google DataTable .Net Wrapper,可在 Nuget。我的博客中有一篇关于它的小文章 http://nicholasbering.ca/dot-net/2014/10/24/google-data-table-dot-net-wrapper/,但总而言之,你可以做类似的事情 下列的。
上面的示例适用于数组,但它应该适用于任何
IEnumrable
。I use Google DataTable .Net Wrapper, available on Nuget. I have a little article about it in my blog at http://nicholasbering.ca/dot-net/2014/10/24/google-data-table-dot-net-wrapper/, but to sum it up you could do something like the following.
The example above is working on an array, but it should work on any
