Question

当我在应用程序中发现内存泄漏时，我使用分析工具来检测非托管内存是否在不断增加;然后我使用二进制搜索方法来定位可能导致内存问题的API。这意味着如果在函数上下文中调用API，则存在内存问题;如果API在代码中被注释，则内存问题不会显示出来。附上代码供您参考：

class Program
{

    private static void Main(string[] args)
    {
        Accelerometer acc = Accelerometer.GetDefault();
        if (acc == null)
        {
            Console.WriteLine("NULL instance received");
            return;
        }
        Console.WriteLine("acc created taking sample");
        var reading = acc.GetCurrentReading();
        if (reading == null)
        {

        }
        else
        {

        }
        acc.ReadingChanged += acc_ReadingChanged; ;
        Console.WriteLine("Press enter to exit");
        Console.ReadLine();

    }

    private static void acc_ReadingChanged(Accelerometer sender, AccelerometerReadingChangedEventArgs args)
    {
        var reading = args.Reading;
        // below code is the place where memory leak happens 
        // actually nothing is done here
        // start
        foreach (var item in reading.Properties)
        {
        }
        // end
        double[] Data = new[] { reading.AccelerationX, reading.AccelerationY, reading.AccelerationZ };

        Console.WriteLine(Data[0].ToString() + Data[1].ToString()+Data[2].ToString());
    }
}

代码是否有任何问题，例如使用foreach或KeyPairValue？API链接：https://docs.microsoft.com/en-us/uwp/api/windows.devices.sensors.accelerometerreading

调用C＃Windows API＆＃34;属性＆＃34;
