	Nome membro	Descrizione
	LogBased	The source object for the published article is a table. Data changes are read from the transaction log. The LogBased option is supported only for transactional and snapshot replication. This option is the default for transactional and snapshot replication.
	ManualFilterProc	The user defines the stored procedure that filters the article horizontally. The ManualFilterProc option is supported only for transactional and snapshot replication. You must also include a value of LogBased or IndexedView to specify the type of object that is being published. When you create an article by using ManualFilterProc, you must specify the name of the filtering stored procedure for FilterProcName.
	LogBasedManualFilterProc	The source object for the published article is a table. Data changes are read from the transaction log, and the user defines the stored procedure that filters the article horizontally. The LogBasedManualFilterProc option is supported only for transactional and snapshot replication. When you create an article by using LogBasedManualFilterProc, you must specify the name of the filtering stored procedure for FilterProcName.
	ManualSyncView	The user defines the object that provides the initial snapshot data for the article. The ManualSyncView option is supported only for transactional and snapshot replication. You must also include a value of LogBased or IndexedView to specify the type of object that is being published. When you create an article by using ManualSyncView, you must specify the name of the object that provides the initial snapshot data for SnapshotObjectName.
	LogBasedManualSyncView	The source object for the published article is a table. Data changes are read from the transaction log, and the user defines the object that provides the initial snapshot data for the article. The LogBasedManualSyncView option is supported only for transactional and snapshot replication. When you create an article by using LogBasedManualSyncView, you must specify the name of the object that provides the initial snapshot data for SnapshotObjectName.
	LogBasedManualBoth	The source object for the published article is a table. Data changes are read from the transaction log. The user defines the object that provides the initial snapshot data for the article and the stored procedure that filters the article horizontally. The LogBasedManualBoth option is supported only for transactional and snapshot replication. When you create an article by using LogBasedManualBoth, you must specify the name of the filtering stored procedure for FilterProcName and the name of the object that provides the initial snapshot data for SnapshotObjectName.
	ProcExecution	The source for the published article is the execution of a stored procedure. The commands in the stored procedure are replicated to the Subscriber. The ProcExecution option is supported only for transactional replication.
	SerializableProcExecution	The source for the published article is the execution of a stored procedure. Only the commands of the stored procedure that are within the context of a transaction that can be serialized are replicated to the Subscriber. The SerializableProcExecution option is supported only for transactional replication.
	TableBased	The source object for the published article is a table. The TableBased option is supported only for merge replication.
	ProcSchemaOnly	The source object for the published article is the schema definition of a stored procedure. The ProcSchemaOnly option is supported for all types of replication.
	ViewSchemaOnly	The source object for the published article is the schema definition of a view. Only the view definition is published. Changes made to data in the view are not replicated. The ViewSchemaOnly option is supported only for merge replication.
	FunctionSchemaOnly	The source object for the published article is the schema definition of a user-defined function. The FunctionSchemaOnly option is supported for all types of replication.
	AggregateSchemaOnly	The source object for the published article is the schema definition of a user-defined aggregate function. The AggregateSchemaOnly option is supported only for transactional and snapshot replication.
	SynonymSchemaOnly	The source object for the published article is the schema definition of a synonym. The SynonymSchemaOnly option is supported for all types of replication.
	IndexedView	The source object for the published article is an indexed view. IndexedView is the base value for all indexed view article types.
	IndexedViewLogBased	The source object for the published article is an indexed view, and data changes are read from the log. The IndexedViewLogBased option is supported only for transactional and snapshot replication.
	IndexedViewLogBasedManualFilterProc	The source object for the published article is an indexed view. Data changes are read from the transaction log, and the user defines the stored procedure that filters the article horizontally. The IndexedViewLogBasedManualFilterProc option is supported only for transactional and snapshot replication. When you create an article by using IndexedViewLogBasedManualFilterProc, you must specify the name of the filtering stored procedure for FilterProcName.
	IndexedViewLogBasedManualSyncView	The source object for the published article is an indexed view. Data changes are read from the transaction log, and the user defines the object that provides the initial snapshot data for the article. The IndexedViewLogBasedManualSyncView option is supported only for transactional and snapshot replication. When you create an article by using IndexedViewLogBasedManualSyncView, you must specify the name of the object that provides the initial snapshot data for SnapshotObjectName.
	IndexedViewLogBasedManualBoth	The source object for the published article is an indexed view. Data changes are read from the transaction log. The user defines the object that provides the initial snapshot data for the article and the stored procedure that filters the article horizontally. The IndexedViewLogBasedManualBoth option is supported only for transactional and snapshot replication. When you create an article by using IndexedViewLogBasedManualBoth, you must specify the name of the filtering stored procedure for FilterProcName and the name of the object that provides the initial snapshot data for SnapshotObjectName.
	IndexedViewSchemaOnly	The source object for the published article is the schema definition of an indexed view. The IndexedViewSchemaOnly option is supported for all types of replication.

Osservazioni

The field values of ArticleOptions are equivalent to the supported values of the @type parameter in sp_addarticle (Transact-SQL) and sp_addmergearticle (Transact-SQL).

The ArticleOptions enumeration supports the FlagsAttribute option, which allows a bitwise combination of enumeration values. However, each supported article type has a separate value, so bitwise operations are not required.

Not all ArticleOptions are supported for all types of replication.

This namespace, class, or member is supported only in the Microsoft .NET Framework version 2.0.
