InvokeDeviceMethodAsync(String, CloudToDeviceMethod, CancellationToken)

以交互方式在设备上调用 方法。 cloudToDeviceMethod 中的超时时间增加了 15 秒，以考虑连接请求所花费的时间

public virtual System.Threading.Tasks.Task<Microsoft.Azure.Devices.CloudToDeviceMethodResult> InvokeDeviceMethodAsync (string deviceId, Microsoft.Azure.Devices.CloudToDeviceMethod cloudToDeviceMethod, System.Threading.CancellationToken cancellationToken = default);

abstract member InvokeDeviceMethodAsync : string * Microsoft.Azure.Devices.CloudToDeviceMethod * System.Threading.CancellationToken -> System.Threading.Tasks.Task<Microsoft.Azure.Devices.CloudToDeviceMethodResult>
override this.InvokeDeviceMethodAsync : string * Microsoft.Azure.Devices.CloudToDeviceMethod * System.Threading.CancellationToken -> System.Threading.Tasks.Task<Microsoft.Azure.Devices.CloudToDeviceMethodResult>

Public Overridable Function InvokeDeviceMethodAsync (deviceId As String, cloudToDeviceMethod As CloudToDeviceMethod, Optional cancellationToken As CancellationToken = Nothing) As Task(Of CloudToDeviceMethodResult)

参数

deviceId

String

cancellationToken

CancellationToken

用于取消操作的取消标记。

返回

Task<CloudToDeviceMethodResult>

CloudToDeviceMethodResult

例外

ArgumentNullException

当 cloudToDeviceMethod 为 NULL 时。
