주의

The DistributionPublisher class requires a connection to the Distributor that is used by the Publisher.

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