属性值
A Boolean value that specifies whether the database is enabled for transaction or snapshot publishing or not. If true, the database is enabled for transactional or snapshot publishing. If false, the database is not enabled for transactional or snapshot publishing.
备注
The EnabledTransPublishing property can only be set by members of the sysadmin fixed server role.
The EnabledTransPublishing property can be retrieved by the sysadmin fixed server role on the server, by the db_owner fixed database role on the replication database, and by a user in the public access list (PAL) for a publication published from the replication database.
Setting EnabledTransPublishing is equivalent to executing sp_replicationdboption (Transact-SQL).
Getting EnabledTransPublishing is equivalent to executing sp_helpreplicationdboption (Transact-SQL).
The EnabledTransPublishing property is available with SQL Server 7.0, SQL Server 2000, and SQL Server 2005.
This namespace, class, or member is supported only in version 2.0 of the .NET Framework.

This example enables transactional and snapshot publishing on AdventureWorks.

// but do not create it now.
