Fields

DefaultOperationTimeoutInMilliseconds

Default operation timeout.

Properties

DiagnosticSamplingPercentage	Diagnostic sampling percentage value, [0-100]; 0 means no message will carry on diagnostics info
OperationTimeoutInMilliseconds	Stores the timeout used in the operation retries. Note that this value is ignored for operations where a cancellation token is provided. For example, SendEventAsync(Message) will use this timeout, but SendEventAsync(Message, CancellationToken) will not. The latter operation will only be canceled by the provided cancellation token.
ProductInfo	Stores custom product information that will be appended to the user agent string that is sent to IoT hub.
RetryPolicy	Obsolete. Stores the retry strategy used in the operation retries.

Dispose()	Releases the unmanaged resources used by the DeviceClient and optionally disposes of the managed resources.

GetFileUploadSasUriAsync(FileUploadSasUriRequest, CancellationToken)	Get a file upload SAS URI which the Azure Storage SDK can use to upload a file to blob for this device See this documentation for more details.
GetTwinAsync()	Retrieve the device twin properties for the current device. For the complete device twin object, use Microsoft.Azure.Devices.RegistryManager.GetTwinAsync(string deviceId).
GetTwinAsync(CancellationToken)	Retrieve the device twin properties for the current device. For the complete device twin object, use Microsoft.Azure.Devices.RegistryManager.GetTwinAsync(string deviceId).
OpenAsync()	Explicitly open the DeviceClient instance.
OpenAsync(CancellationToken)	Explicitly open the DeviceClient instance.
ReceiveAsync()	Receive a message from the device queue using the default timeout. After handling a received message, a client should call CompleteAsync(Message), AbandonAsync(Message), or RejectAsync(Message), and then dispose the message.
ReceiveAsync(CancellationToken)	Receive a message from the device queue using the cancellation token. After handling a received message, a client should call CompleteAsync(Message, CancellationToken), AbandonAsync(Message, CancellationToken), or RejectAsync(Message, CancellationToken), and then dispose the message.
ReceiveAsync(TimeSpan)	Receive a message from the device queue using a timeout. After handling a received message, a client should call CompleteAsync(Message, CancellationToken), AbandonAsync(Message, CancellationToken), or RejectAsync(Message, CancellationToken), and then dispose the message.

SendEventBatchAsync(IEnumerable<Message>)	Sends a batch of events to IoT hub. Use AMQP or HTTPs for a true batch operation. MQTT will just send the messages one after the other.
SetConnectionStatusChangesHandler(ConnectionStatusChangesHandler)	Sets a new delegate for the connection status changed callback. If a delegate is already associated, it will be replaced with the new delegate. Note that this callback will never be called if the client is configured to use HTTP, as that protocol is stateless.
SetDesiredPropertyUpdateCallback(DesiredPropertyUpdateCallback, Object)	Obsolete. Set a callback that will be called whenever the client receives a state update (desired or reported) from the service. This has the side-effect of subscribing to the PATCH topic on the service.
SetDesiredPropertyUpdateCallbackAsync(DesiredPropertyUpdateCallback, Object, CancellationToken)	Set a callback that will be called whenever the client receives a state update (desired or reported) from the service. Set callback value to null to clear.
SetDesiredPropertyUpdateCallbackAsync(DesiredPropertyUpdateCallback, Object)	Set a callback that will be called whenever the client receives a state update (desired or reported) from the service. Set callback value to null to clear.
SetMethodDefaultHandlerAsync(MethodCallback, Object, CancellationToken)	Sets a new delegate that is called for a method that doesn't have a delegate registered for its name. If a default delegate is already registered it will replace with the new delegate. A method handler can be unset by passing a null MethodCallback.
SetMethodDefaultHandlerAsync(MethodCallback, Object)	Sets a new delegate that is called for a method that doesn't have a delegate registered for its name. If a default delegate is already registered it will replace with the new delegate. A method handler can be unset by passing a null MethodCallback.
SetMethodHandler(String, MethodCallback, Object)	Obsolete. Sets a new delegate for the named method. If a delegate is already associated with the named method, it will be replaced with the new delegate.
SetMethodHandlerAsync(String, MethodCallback, Object, CancellationToken)	Sets a new delegate for the named method. If a delegate is already associated with the named method, it will be replaced with the new delegate. A method handler can be unset by passing a null MethodCallback.
SetMethodHandlerAsync(String, MethodCallback, Object)	Sets a new delegate for the named method. If a delegate is already associated with the named method, it will be replaced with the new delegate. A method handler can be unset by passing a null MethodCallback.
SetReceiveMessageHandlerAsync(ReceiveMessageCallback, Object, CancellationToken)	Sets a new delegate for receiving a message from the device queue using a cancellation token. After handling a received message, a client should call CompleteAsync(Message, CancellationToken), AbandonAsync(Message, CancellationToken), or RejectAsync(Message, CancellationToken), and then dispose the message. If a null delegate is passed, it will disable the callback triggered on receiving messages from the service.
SetRetryPolicy(IRetryPolicy)	Sets the retry policy used in the operation retries. The change will take effect after any in-progress operations.
UpdateReportedPropertiesAsync(TwinCollection, CancellationToken)	Push reported property changes up to the service.
UpdateReportedPropertiesAsync(TwinCollection)	Push reported property changes up to the service.
UploadToBlobAsync(String, Stream, CancellationToken)	Obsolete. Uploads a stream to a block blob in a storage account associated with the IoTHub for that device. If the blob already exists, it will be overwritten.
UploadToBlobAsync(String, Stream)	Obsolete. Uploads a stream to a block blob in a storage account associated with the IoTHub for that device. If the blob already exists, it will be overwritten.
