c# - 以编程方式访问 Motorola MC9500 运动传感器？

Question

我目前正在为 Motorola MC9500 开发 Windows Mobile 应用程序，该应用程序具有 Windows Mobile 6.5。 我尝试过使用 Symbol 的 EMDK 库来访问设备的内置运动传感器，但没有成功。

.NET v2.7 的 EMDK 中有 Symbol.Sensor 类库，该类库应该可以访问所有内置传感器，但我不知道如何使用它。

Symbol.Sensor.SensorManager manager = new Symbol.Sensor.SensorManager();

我在这里收到一个 MissingMethodException 异常，说... “找不到 PInvoke DLL SensorsAPI.dll。”

我应该如何使用 C# 访问运动传感器？

如果还有其他选择，请告知。

我将发布一个 dllImport 示例作为@HemendraSharma 评论的继续。上面的代码是为移动设备编写的，用于更改系统时间。
