Notes

Calling RemoveMergePartition is equivalent to executing sp_dropmergepartition.

The RemoveMergePartition method can only be called by members of the sysadmin fixed server role at the Publisher or by members of the db_owner fixed database role on the publication database.

The RemoveMergePartition method is available only for instances of Microsoft SQL Server 2005.

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

Exemple

// Define the Publisher, publication, and databases.
string publicationName = "AdvWorksSalesOrdersMerge";
string publisherName = publisherInstance;
string subscriberName = subscriberInstance;
string subscriptionDbName = "AdventureWorksReplica";
string publicationDbName = "AdventureWorks";

//Create connections to the Publisher and Subscriber.
ServerConnection subscriberConn = new ServerConnection(subscriberName);
ServerConnection publisherConn = new ServerConnection(publisherName);

// Create the objects that we need.
MergePublication publication;
MergePullSubscription subscription;

try
{
    // Connect to the Subscriber.
    subscriberConn.Connect();

    // Define the pull subscription.
    subscription = new MergePullSubscription();

    subscription.PublisherName = publisherName;
    subscription.PublicationName = publicationName;
    subscription.PublicationDBName = publicationDbName;

    // Define the publication.
    publication = new MergePublication();
    publication.Name = publicationName;
    publication.DatabaseName = publicationDbName;

    // Delete the pull subscription, if it exists.
