備註

The MergeSubscription class is used with both pull and push subscriptions to a merge publication.

When configuring a Publisher with a remote Distributor, the values supplied for all parameters, including SynchronizationAgentProcessSecurity, are sent to the Distributor as plain text. You should encrypt the connection between the Publisher and its remote Distributor before calling the Create method. For more information, see 加密 SQL Server 的連接.

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

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.
