HttpResponse作爲字符串 - 將數字轉換爲字母

我連接到一個Web API並要求響應，但我的響應顯示不正確，如「高」：4.166e-5當我期望像0.00004166像數字I我要求的是BTC的市場價格，我認爲這是一個32位整數的問題，但它的一個字符串，所以我失去了。對不起，如果我沒有解釋得很好。HttpResponse作爲字符串 - 將數字轉換爲字母

這是我讀的響應：

`{"date":1493626200,"high":4.166e-5,"low":4.158e-5,"open":4.166e-5,"close":4.158e-5,"volume":0.05681982,"quoteVolume":1364.65936831,"weightedAverage":4.163e-5}]

這是怎麼IM格式化的HttpResponse

` Dim response As HttpResponseMessage = client.PostAsync(privUrl, myContent).Result 

     If response.IsSuccessStatusCode Then 
      Dim json As String = response.Content.ReadAsStringAsync().Result 
      Return json 
     End If

，然後用這個

 Dim json As String = JsonConvert.DeserializeObject(responseFromServer).ToString()

編輯解串***

現在我使用EuX0示例，但仍然出現錯誤無法反序列化當前的JSON數組（例如， [1,2,3]）轉換成類型 'class_test.FormatOutputData'，因爲類型需要JSON對象

Dim responseFromServer As String = apiSettings.TradingApi("returnTradeHistory&currencyPair=BTC_XRP") 
TextBox1.AppendText(responseFromServer) 'so i can see whats coming in 
Dim jsonString As String = responseFromServer 
**Dim obj As FormatOutputData = JsonConvert.DeserializeObject(Of FormatOutputData)(jsonString)** 
obj.outputValues()

這是輸出的整個JSON輸出[{"globalTradeID":116229026,"tradeID":"4728521","date":"2017-05-01

第一個問題是您的JSON字符串不完整。它應該以「]」結尾而不是逗號。所以，如果你能提供完整的字符串，那就太棒了。此外，您的例子JSON字符串包含FormatOutPutData對象不止一個，所以你需要做的是這樣的：昏暗的OBJ（）作爲FormatOutPutData = JsonConvert.DeserializeObject（中FormatOutputData（））（jsonString），然後顯示它像：OBJ（X）.outputValues（） – EuX0

我已經更新了JSON，輸出我現在有你的例子是全球TradeID：116226661 TradeID：4728312 高：0 低：0 開放：0 關閉：0 容量：0 QuoteVolume：0 加權平均：0，但這些都缺少信息 –

你的json字符串仍然搞砸我相信在它的中間不應該是「jsonString：」。此外，信息不存在，因爲您的json字符串只包含globalTradeID，tradeID，日期，費率，金額，總額，費用，訂單編號，類型和類別。查看我的原始答案更新代碼。 – EuX0

非常感謝您的時間EuX0，我知道我現在需要什麼，只有一個問題，爲什麼數字原來會像4.166e-5一樣回來？什麼讓數字轉換爲字母？ –

如果它是從服務器那裏傳來的，那恐怕我不知道。一種可能性是發送4.166e-5而不是0.00004166超過數百萬的請求爲您節省一些帶寬，但這純粹是猜測。編輯：爲了將數字轉換爲字母，它被稱爲電子符號。 – EuX0

非常感謝，祝你有美好的一天。 –
