[英]Deserialize JSON Objects to .Net List (C#)
I have a JSON-String (below). 我有一个JSON-String(如下)。 I want to deserialize it to a C# Object and get the data as a list.
我想将其反序列化为C#对象并以列表的形式获取数据。 My problem is, that the data is not available in an JSON array.
我的问题是,该数据在JSON数组中不可用。 How do I need to prepare my solution that I can get data in this structure:
我需要如何准备解决方案以获取以下结构的数据:
For Sensor 1 - n I just need the GUIDs in a list. 对于传感器1-n,我只需要列表中的GUID。 The data behind is not relevant.
后面的数据无关紧要。
In the Code I replaced all GUIDs with "GUID" 在代码中,我将所有GUID替换为“ GUID”
{
"object": {
"GUID": {
"type": "sensor",
"owner": "GUID",
"time": 1482499665,
"description": "Temperatursensor 1",
"sdevice": "00003639",
"model": "SOLUCON Industry Temperature",
"tag": [
"GUID",
"GUID"
]
},
"GUID": {
"type": "sensor",
"owner": "GUID",
"time": 1482499758,
"description": "Wassersensor 1",
"sdevice": "000056d9",
"model": "SOLUCON Industry Water",
"tag": [
"GUID",
"GUID"
]
},
"GUID": {
"type": "sensor",
"owner": "GUID",
"time": 1482499797,
"description": "Rauchmelder 1",
"sdevice": "00008519",
"model": "TG551A",
"tag": [
"GUID",
"GUID"
]
},
"GUID": {
"type": "sensor",
"owner": "GUID",
"time": 1483888365,
"description": "SOLUCON Industry Multi 2",
"sdevice": "0000d409",
"model": "SOLUCON Industry Multi",
"tag": [
"GUID",
"GUID"
]
}
},
"status": "ok"
}
You could use the Newtonsoft.Json package like so: 您可以像这样使用Newtonsoft.Json包:
var jsonString = ...
var result = JsonConvert.DeserializeObject<IDictionary<string, object>>(jsonString);
var obj = (JObject)result["object"];
foreach (var prop in obj.Properties())
{
Console.WriteLine(prop.Name);
}
This will print all the GUID properties of the object
node. 这将打印
object
节点的所有GUID属性。
And if you wanted to get the extra objects you could define a model: 如果您想获得额外的对象,则可以定义一个模型:
public class Item
{
public string Type { get; set; }
public Guid Owner { get; set; }
public string Description { get; set; }
public IList<string> Tag { get; set; }
...
}
and then you could get the sensor like this: 然后您可以像这样获得传感器:
foreach (var prop in obj.Properties())
{
Console.WriteLine(prop.Name);
Sensor sensor = prop.Value.ToObject<Sensor>();
}
Structure you provided looks like a dictionary so it should deserialize to: 您提供的结构看起来像字典,因此应反序列化为:
class Data
{
public Dictionary<Guid, Sensor> Object {get;set;}
}
From this you can extract list of keys ( data.Object.Keys
) that will contain your list of Guids. 从中可以提取将包含
data.Object.Keys
列表的键列表( data.Object.Keys
)。
