如何在VB.net中获取JSON数组或对象的值？

Question

我有以下数据的JSON文件。我只想获取“命名”和“单位”的数据。请协助我如何在VB.net中执行此操作？

[
        {
            "customerId": "999",
            "deviceId": "XXX999",
            "searchDeviceId": "D_XXX999",
            "utc": "2016-04-28T03:37:00.000Z",
            "lat": 22.5691,
            "lng": 120.3058,
            "sensors": [
                {
                    "naming": "ABC123",
                    "factor": null,
                    "unit": "k",
                    "period": null
                },
                {
                    "naming": "XYZ123",
                    "factor": null,
                    "unit": "c",
                    "period": null
                },
                .
                .
                .
                .
                .
            ]
        }
    ]

对于C＃：

JObject jResults = JObject.Parse("JsonString");
String naming = jResults["sensors"]["naming "];
String unit = jResults["sensors"]["unit "];

对于VB：

Dim jResults As JObject = JObject.Parse("JsonString")
Dim naming As [String] = jResults("sensors")("naming ")
Dim unit As [String] = jResults("sensors")("unit ")

您可以这样实现。
