Public Overridable Function UpdateAsync (twins As IEnumerable(Of ClientTwin), Optional onlyIfUnchanged As Boolean = false, Optional cancellationToken As CancellationToken = Nothing) As Task(Of BulkRegistryOperationResult)
Parameters
- twins
- IEnumerable<ClientTwin>
List of ClientTwins with updated fields.
- onlyIfUnchanged
- Boolean
If false, this operation will be performed even if the provided device identity has an out of date ETag. If true, the operation will throw a IotHubServiceException with PreconditionFailed if the provided device identity has an out of date ETag. An up-to-date ETag can be retrieved using GetAsync(String, String, CancellationToken).
- cancellationToken
- CancellationToken
Task cancellation token.
Returns
updated module twin.
Exceptions
When the provided twins
is null.
When the provided twins
enumeration is empty.
When a twin is missing an expected ETag.
If IoT hub responded to the request with a non-successful status code. For example, if the provided request was throttled, IotHubServiceException with ThrottlingException is thrown. For a complete list of possible error cases, see IotHubServiceErrorCode.
If the HTTP request fails due to an underlying issue such as network connectivity, DNS failure, or server certificate validation.
If the provided cancellationToken
has requested cancellation.
Applies to
UpdateAsync(String, ClientTwin, Boolean, CancellationToken)
Updates the mutable fields of a module's twin.

Public Overridable Function UpdateAsync (deviceId As String, twinPatch As ClientTwin, Optional onlyIfUnchanged As Boolean = false, Optional cancellationToken As CancellationToken = Nothing) As Task(Of ClientTwin)
Parameters
- deviceId
- String
The device Id.
- twinPatch
- ClientTwin
Twin with updated fields.
- onlyIfUnchanged
- Boolean
If false, this operation will be performed even if the provided device identity has an out of date ETag. If true, the operation will throw a IotHubServiceException with PreconditionFailed if the provided device identity has an out of date ETag. An up-to-date ETag can be retrieved using GetAsync(String, String, CancellationToken).
- cancellationToken
- CancellationToken
Task cancellation token.
Returns
Updated device twin.
Exceptions
When the provided deviceId
or twinPatch
is null.
If the deviceId
is empty or white space.
If IoT hub responded to the request with a non-successful status code. For example, if the provided request was throttled, IotHubServiceException with ThrottlingException is thrown. For a complete list of possible error cases, see IotHubServiceErrorCode.
If the HTTP request fails due to an underlying issue such as network connectivity, DNS failure, or server certificate validation.
If the provided cancellationToken
has requested cancellation.
Applies to

Parameters
- deviceId
- String
The device Id.
- moduleId
- String
The module Id.
