	CallMethod	Overloaded. Calls (invokes) a method (or methods) in an OPC server. This method calls (invokes) a method (or methods) in an OPC server. Input and output arguments can be passed to/from methods.
	ChangeDataChangeSubscription	Changes parameters of a data change subscription. Specify the handle, a new sampling interval and absolute deadband value.
	ChangeMonitoredItemSubscription	Overloaded. Changes parameters of a subscription to a particular monitored item. It is more efficient to change multiple subscriptions using `MultipleMonitoredItemSubscriptions` method.
	ChangeMultipleDataChangeSubscriptions	Changes parameters of multiple data change subscriptions. Specify the handles, a new sampling interval and absolute deadband value.
	ChangeMultipleMonitoredItemSubscriptions	Overloaded. Changes parameters of multiple subscriptions. Specify the handles, and a new sampling interval.
	DiscoverGlobalApplications	Overloaded. Globally discovers OPC-UA applications, using the specified GDS endpoint. This method globally discovers OPC-UA applications that meet the specified filters and returns information about them, using the specified GDS endpoint.
	DiscoverGlobalServers	Overloaded. Globally discovers OPC-UA servers, using the specified GDS endpoint. This method globally discovers OPC-UA servers and returns information about them, using the specified GDS endpoint, and an empty filter.
	DiscoverLocalApplications	Overloaded. Discovers OPC-UA applications available on the discovery host. This method discovers available OPC-UA applications and returns information about them, using the specified discovery host, and filtering by specified application types. It uses the so-called Local Discovery Server (LDS). You can influence how the discovery works using the properties in static EasyUAClientCore.SharedParameters. Invokes the FindServers service. See also in Knowledge Base: Technical note-OPC UA Discovery in QuickOPC.
	DiscoverLocalEndpoints	Overloaded. Discovers available endpoints for a given server discovery URL. The query is performed using a GetEndpoints service of an OPC server specified by its discovery endpoint. See also in Knowledge Base: Technical note-OPC UA Discovery in QuickOPC.
	DiscoverLocalServers	Overloaded. Discovers OPC-UA servers available on the discovery host. This method discovers OPC-UA servers and returns information about them, using the specified discovery host. It uses the so-called Local Discovery Server (LDS). You can influence how the discovery works using the properties in static EasyUAClientCore.SharedParameters. Invokes the FindServers service. See also in Knowledge Base: Technical note-OPC UA Discovery in QuickOPC.
	DiscoverNetworkServers	Overloaded. Discovers available OPC-UA servers on the network. This method discovers available OPC-UA servers on the network and returns information about them. It uses the so-called Local Discovery Server with Multicast Extensions (LDS-NE). You can influence how the discovery works using the properties in EasyUAClientCore.SharedParameters. Invokes the FindServersOnNetwork service. See also in Knowledge Base: Technical note-OPC UA Discovery in QuickOPC.
	Equals	(Inherited from object)
	FindLocalApplications	Overloaded. Discovers available OPC-UA applications, using the specified discovery URI strings. This method discovers available OPC-UA applications and returns information about them, using the specified discovery URI strings and filtering by specified application types. It uses the discovery services on specified discovery endpoints. Invokes the FindServers service. The discovery may be attempted in parallel on the specified endpoints, depending on component settings. See also in Knowledge Base: Technical note-OPC UA Discovery in QuickOPC.
	GetHashCode	Serves as the default hash function. (Inherited from object)
	GetType	Gets the System.Type of the current instance. (Inherited from object)
	PullDataChangeNotification	Attempts to pull an OPC data change notification subscribed to by the SubscribeMultipleMonitoredItems or SubscribeDataChange method.
	PullEventNotification	Attempts to pull an OPC event notification subscribed to by the SubscribeMultipleMonitoredItems or SubscribeEvent method.
	Read	Overloaded. Reads attribute data from an OPC server. Value, status code, and timestamps are returned.
	ReadMultiple	Overloaded. Reads values of multiple attributes.
	ReadMultipleValues	Overloaded. Reads values of multiple attributes.
	ReadValue	Overloaded. Reads an attribute from an OPC server. Only the attribute's value is returned (status code and timestamps are not returned). The status code must be 'good' for this method to succeed; otherwise, a OpcLabs.EasyOpc.UA.OperationModel.UAException is thrown.
	SubscribeDataChange	Overloaded. Subscribe to a data change. Specify an endpoint descriptor, node id, and sampling interval.
	SubscribeEvent	Overloaded. Subscribe to an event. Specify an endpoint descriptor, node id, and sampling interval.
	SubscribeMonitoredItem	Overloaded. Subscribe to changes of a particular monitored item. For each significant monitored item change, either the IEasyUAClient.DataChangeNotification event is generated, or a specified callback method is invoked. It is more efficient to subscribe to multiple monitored items using SubscribeMultipleMonitoredItems method.
	SubscribeMultipleDataChanges	Subscribe to changes of multiple OPC monitored items with a data change callback method. The IEasyUAClient.DataChangeNotification event will be generated for each significant item change, and a specified callback method will be invoked.
	SubscribeMultipleEvents	Subscribe to changes of multiple OPC monitored items with an event notification callback method. The IEasyUAClient.EventNotification event will be generated for each significant item change, and a specified callback method will be invoked.
	SubscribeMultipleMonitoredItems	Subscribe to changes of multiple OPC monitored items. The IEasyUAClient.DataChangeNotification or IEasyUAClient.EventNotification event will be generated for each significant item change.
	ToString	Returns a string that represents the current object. (Inherited from object)
	UnsubscribeMonitoredItem	Unsubscribe from changes of a particular monitored item. Unsubscribe from monitored item, specifying its handle.
	Write	Overloaded. Writes into an attribute in an OPC server. Value, status code and timestamps are written.
	WriteMultipleValues	Writes values into multiple attributes, using array of argument objects as an input (status codes and timestamps are not written).
	WriteValue	Overloaded. Writes a value into an attribute an OPC server. Only the item value is written (status code and timestamps are not written).
