GetSystemHistoryAsync(DateTime)

编辑

异步获取特定时间的传感器读数。

public:
 static IAsyncOperation<IVectorView<PedometerReading ^> ^> ^ GetSystemHistoryAsync(DateTime fromTime);

/// [Windows.Foundation.Metadata.Overload("GetSystemHistoryAsync")]
/// [Windows.Foundation.Metadata.RemoteAsync]
 static IAsyncOperation<IVectorView<PedometerReading>> GetSystemHistoryAsync(DateTime const& fromTime);

[Windows.Foundation.Metadata.Overload("GetSystemHistoryAsync")]
[Windows.Foundation.Metadata.RemoteAsync]
public static IAsyncOperation<IReadOnlyList<PedometerReading>> GetSystemHistoryAsync(System.DateTimeOffset fromTime);

function getSystemHistoryAsync(fromTime)

Public Shared Function GetSystemHistoryAsync (fromTime As DateTimeOffset) As IAsyncOperation(Of IReadOnlyList(Of PedometerReading))

参数

fromTime: DateTime DateTimeOffset

要检索读取的时间。

IAsyncOperation<IVectorView<PedometerReading>>

IAsyncOperation<IReadOnlyList<PedometerReading>>

异步返回表示传感器相关信息的 PedometerReading 对象的列表。

属性: OverloadAttribute RemoteAsyncAttribute
