从案例语句C#中获取数据

问题描述

我使用的是我们购买的热成像仪的SDK。实际上我是一个PHP Web开发人员,现在我必须用.Net编写代码

一个案例,但我真的不知道如何从中获取数据。

 private void OnDetect(CallbackEventArgument callbackArgument)
 {
    var detectionResult = callbackArgument.GetDetectionResult();
    var firstDetection = detectionResult.Sequence.Items.First();

    var message = string.Empty;
    ImageArgument fullSizeImage = null;
    switch (detectionResult.Type)
    {
       case T3DDetectionType.OBSERVATION:
          message = "Track ID: " + firstDetection.TrackId;
          fullSizeImage = detectionResult.RGBImage;
          break;
       case T3DDetectionType.DEPTH_LIVEnesS:
       case T3DDetectionType.THERMAL_LIVEnesS:
          message = "Track ID: " + firstDetection.TrackId + " score: " + (firstDetection as Liveness).score.ToString("N0");
          fullSizeImage = detectionResult.FullImage;
          break;
       case T3DDetectionType.TEMPERATURE:
          message = "Temperature: " + (firstDetection as Temperature).MeasurementValueCelsius.ToString("N1") + "°C";
          fullSizeImage = detectionResult.FullImage;
          break;
    }

因此,我想做的是能够在案件之后获取(firstDetection as Liveness).score.ToString("N0")firstDetection.TrackId(firstDetection as Temperature).MeasurementValueCelsius.ToString("N1") + "°C"的数据并创建一个JSON。

创建json可行,但是我无法调用数据。

解决方法

如果您希望在switch语句中使用某些内容,则只需执行以下操作:

  • 在switch语句之前声明一个变量
string firstDetection = string.Empty;
  • 然后将所需的值分配给开关盒内的该变量。
case T3DDetectionType.TEMPERATURE:
   message = "Temperature: " + (firstDetection as Temperature).MeasurementValueCelsius.ToString("N1") + "°C";
   firstDetection = (firstDetection as Temperature).MeasurementValueCelsius.ToString("N1") + "°C";
   fullSizeImage = detectionResult.FullImage;
   break;

现在,在switch语句之后,您将在变量firstDetection中拥有所需的值。
