Notes

The RemovePullSubscription method can only be called by members of the sysadmin fixed server role at the Publisher, by members of the db_owner fixed database role on the publication database, or by the user that created the subscription being removed.

Calling RemovePullSubscription is equivalent to executing sp_dropsubscription.

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