備註

ReplicationDatabase can be used to represent a publication or subscription database. ReplicationDatabase cannot be used to represent system databases, such as master, tempdb, msdb, and model. A distribution database is represented by DistributionDatabase.

Thread Safety

Any public static (Shared in Microsoft Visual Basic) members of this type are safe for multithreaded operations. Any instance members are not guaranteed to be thread safe.
