以编程方式访问Motorola MC9500运动传感器？

Question

我目前正在使用Motorola MC9500的{​​{1}}的Windows移动应用程序。Windows Mobile 6.5。 我已经尝试使用Symbol的EMDK库来访问设备的内置运动传感器而没有任何运气。

EMDK for .NET v2.7中有Symbol.Sensor类库，应该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();

我在这里得到一个MissingMethodException例外，说......  “找不到PInvoke DLL SensorsAPI.dll。”

如何使用C＃访问运动传感器？

如果还有其他选择，请告诉我们。

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

using System;
using System.Runtime.InteropServices;

namespace changeHour
{   

public class cDateTime  
{       

    [StructLayout(LayoutKind.Sequential)]       
    private struct SystemTime

Answer 2

这是我到目前为止得出的结论...... Motorola MC9500的传感器无法以编程方式访问。
