)

Remarks

The result of the validation operation is written to the agent history, which is viewed using Replication Monitor.

Calling ValidatePublication is equivalent to executing sp_validatemergepublication.

The ValidatePublication 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 ValidatePublication method is available only for instances of Microsoft SQL Server 2000 and Microsoft SQL Server 2005.

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

Example

// Define the server, database, and publication names
string publisherName = publisherInstance;
string publicationName = "AdvWorksSalesOrdersMerge";
string publicationDbName = "AdventureWorks";
string subscriberName = subscriberInstance;
string subscriptionDbName = "AdventureWorksReplica";

MergePublication publication;

// Create a connection to the Publisher.
ServerConnection conn = new ServerConnection(publisherName);

try
{
    // Connect to the Publisher.
    conn.Connect();

    // Set the required properties for the publication.
    publication = new MergePublication();
    publication.ConnectionContext = conn;
    publication.Name = publicationName;
    publication.DatabaseName = publicationDbName;


    // If we can't get the properties for this merge publication, then throw an application exception.
    if (publication.LoadProperties())
    {
        // Initiate validation of the specified subscription.
        publication.ValidateSubscription(subscriberName,
            subscriptionDbName, ValidationOption.RowCountOnly);
        
        // Start the Merge Agent to synchronize and validate the subscription.
