Extension Methods
| Name | Description |
![Public Extension Method](template/packages/core-dotnet/images/extensionmethod.png) | ChangeDataSetFieldSubscription | Overloaded. Changes parameters of an existing dataset field subscription. |
![Public Extension Method](template/packages/core-dotnet/images/extensionmethod.png) | ChangeDataSetSubscription | Changes parameters of an existing dataset subscription, specifying a new filter. |
![Public Extension Method](template/packages/core-dotnet/images/extensionmethod.png) | GetSubscribeDataSetFieldArguments | Obtains parameters of a specified dataset subscription. |
![Public Extension Method](template/packages/core-dotnet/images/extensionmethod.png) | PullDataSetMessage | Attempts to pull a dataset message event notification subscribed to by the SubscribeDataSet method. |
![Public Extension Method](template/packages/core-dotnet/images/extensionmethod.png) | PullResolverAccess | Attempts to pull a resolver access notification. |
![Public Extension Method](template/packages/core-dotnet/images/extensionmethod.png) | PullSubscriptionResolved | Attempts to pull a subscription resolved notification. |
![Public Extension Method](template/packages/core-dotnet/images/extensionmethod.png) | SubscribeDataSet | Overloaded. Subscribes to a dataset, using a PubSub connection descriptor, and no filter. |
![Public Extension Method](template/packages/core-dotnet/images/extensionmethod.png) | SubscribeDataSetField | Overloaded. Subscribes to a single dataset field from a dataset, using arguments object. |
![Public Extension Method](template/packages/core-dotnet/images/extensionmethod.png) | TestConnection | Overloaded. Tests whether an OPC UA PubSub connection can be successfully established. Synchronous.
The method tests synchronously whether an OPC UA PubSub connection can be successfully established. It returns normally when the test passes. The method throws a OpcLabs.EasyOpc.UA.OperationModel.UAException when there is an error establishing the connection.
Due to asynchronous nature of some communication channels, successful test outcome does not always imply that a connection has been fully established.
The waitMilliseconds parameter is not a timeout in its traditional sense, i.e. a maximum time allowed for the operation. Here, this method actually waits for the time given by waitMilliseconds parameter unless a failure occurs. |
![Public Extension Method](template/packages/core-dotnet/images/extensionmethod.png) | TestConnectionAsync | Overloaded. Tests whether an OPC UA PubSub connection can be successfully established. Asynchronous.
The method tests asynchronously whether an OPC UA PubSub connection can be successfully established.

![Public Extension Method](template/packages/core-dotnet/images/extensionmethod.png) | UnsubscribeDataSetField | Unsubscribes from a dataset field specified by its integer handle. |

![Event](template/packages/core-dotnet/images/Event.png) | ResolverAccess | Raised when the OPC UA PubSub resolver accesses its target. |
![Event](template/packages/core-dotnet/images/Event.png) | SubscriptionResolved | Raised when the OPC UA PubSub has resolved the dataset subscription. |
