Question

我想为外部控制电路创建一个库类，通过串口进行通信。该电路具有内置功能，以使用串行通信获得/设置各种设置（例如，发送“SR，HC，01,1，\ r”将传感器1打开）。有大约100个功能分为以下类别：传感器设置，输出设置和环境设置。这是我试过的。

public class CircuitController
{
   // Fields.
   private SerialPort controllerSerialPort;
   private SensorSettings sensorSettings;
   private OutputSettings outputSettings;
   private EnvironmentSettings environmentSettings;
   ...

  // Properties.
  // Properties to get sensorSettings, outputSettings, and environmentSettings.

  // Methods.
  public string SendReceive(string sendCommand)   // Send command and receive response.
  {
     ...
  }

  // Nested classes.
  public class SensorSettings
  {
     // Fields.
     // The various sensor settings here.

     // Properties.
     // Properties to get/set the sensor settings. Note: Get/Set is done through calling one of the following methods.

     // Methods.
     public double GetSensorUnits(int sensorNumber)
     {
        ...
        string commandToSend = String.Format("HE,WL,1,{0}", sensorNumber);   // Setup command string.
        string commandResponse = SendReceive(commandToSend);   // Send command and receive response. ERROR here, cannot access higher level, non-static methods.
        // Logic to process commandResponse.
        ...
     }

     // Other methods to create, send, and process the circuit's sensor settings "functions".

  }

  public class OutputSettings
  {
     // Same logic as SensorSettings class.
  }

  public class EnvironmentSettings
  {
     // Same logic as SensorSettings class.
  }
}

我认为这样就不会在CircuitController类下填充100个方法/属性。例如，我可以使用get属性来获取sensorSettings实例，然后调用所需的方法/属性：circuitControllerInstance.GetSensorSettingsProperty.GetSensorUnits(1);。我收到一个编译错误，我试图从嵌套类访问SendReceive()。有没有办法做到这一点？

谢谢！

嵌套类不会“看到”其主机中声明的内容。

您应该将主机引用传递给任何嵌套类，例如，在构造函数中。
