我最近開始使用vb.net的一個項目,我正在努力弄清楚如何獲取Mid類中的幾個項目的數據o,h,l, c轉換爲double並加載到數組中,最終對它們執行一些數學函數。以下是我希望使用的JSON數據的一小部分(1000箇中的3個)樣本。在VB.NET中反序列化嵌套的JSON進行轉換
{
"instrument": "EUR_USD",
"granularity": "M1",
"candles": [
{
"complete": true,
"volume": 18,
"time": "2017-07-21T04:13:00.000000000Z",
"mid": {
"o": "1.16281",
"h": "1.16284",
"l": "1.16274",
"c": "1.16281"
}
},
{
"complete": true,
"volume": 96,
"time": "2017-07-21T20:58:00.000000000Z",
"mid": {
"o": "1.16640",
"h": "1.16642",
"l": "1.16628",
"c": "1.16628"
}
},
{
"complete": true,
"volume": 32,
"time": "2017-07-21T20:59:00.000000000Z",
"mid": {
"o": "1.16628",
"h": "1.16652",
"l": "1.16628",
"c": "1.16641"
}
}
]
}
下面是相關代碼:
Imports Newtonsoft.Json
Public Class Rootobject
Public Property instrument As String
Public Property granularity As String
Public Property candles() As List(Of Candle)
End Class
Public Class Candle
Public Property complete As Boolean
Public Property volume As Integer
Public Property time As String
Public Property mid As Mid
End Class
Public Class Mid
Public Property o As String
Public Property h As String
Public Property l As String
Public Property c As String
End Class
... 'jsonstring loaded with data here
Dim obj = JsonConvert.DeserializeObject(Of Rootobject)(jsonstring)
我試圖做類似下面的東西用一個循環只接收錯誤。
Dim obj2 = obj.candles(0).mid.o
我也試圖找到使用JObject.Parse(jsonstring)沒有任何成功的方法。那麼,具體來說,將Mid類中的值加載到數組中以便進一步處理的最佳方法是什麼?
在此先感謝。
