JSON字符串到对象数组C＃

Question

My test json is as below..

 string json = "[{Name:'John Simith',Age:35},{Name:'Pablo Perez',Age:34}]"; 

The json could have any key values and so I do not have a class to deserialize it with.. I can deserialize it as IEnumerable as below

IEnumerable<dynamic> data = JsonConvert.DeserializeObject<IEnumerable<dynamic>>(json);

I need to convert it to 2D object arrays : object[,] as below..

[
['John Simith',35],['Pablo Perez',34]
]

Any help is sincerely appreciated. Thanks

Answer 1

If you don't have a C# class to deserialize it to, the best thing to do is to use the dynamic LINQ objects that JSON.NET provides, meaning JObject , JArray and so on. This lets you query the structure dynamically, read types values and so on, without having to fight with C#'s type system:

It would be much easier to traverse the JSON tree and convert to object[,] from those objects.

Answer 2

You can change from dynamic to IDictionary<string, object> in order to be able to enumerate unknown keys. Then a LINQ expression can convert it to an array, like this:

var json = "[{Name:'John Simith',Age:35},{Name:'Pablo Perez',Age:34}]";
var data = JsonConvert.DeserializeObject<IEnumerable<IDictionary<string, object>>>(json);

var array = data.Select(d => d.Values.ToArray()).ToArray();
