           string publicationName = "AdvWorksProductTran";
           string publisherName = publisherInstance;
           string subscriberName = subscriberInstance;
           string subscriptionDbName = "AdventureWorks2012Replica";
           string publicationDbName = "AdventureWorks2012";

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

           // Create the objects that we need.
           TransPublication publication;
           TransSubscription subscription;

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

               // Ensure that the publication exists and that 
               // it supports push subscriptions.
               publication = new TransPublication();
               publication.Name = publicationName;
               publication.DatabaseName = publicationDbName;
               publication.ConnectionContext = conn;

               if (publication.IsExistingObject)
               {
                   if ((publication.Attributes & PublicationAttributes.AllowPush) == 0)
                   {
                       publication.Attributes |= PublicationAttributes.AllowPush;
                   }

                   // Define the push subscription.
                   subscription = new TransSubscription();
                   subscription.ConnectionContext = conn;
                   subscription.SubscriberName = subscriberName;
                   subscription.PublicationName = publicationName;
                   subscription.DatabaseName = publicationDbName;
                   subscription.SubscriptionDBName = subscriptionDbName;

                   // Specify the Windows login credentials for the Distribution Agent job.
                   subscription.SynchronizationAgentProcessSecurity.Login = winLogin;
                   subscription.SynchronizationAgentProcessSecurity.Password = winPassword;

                   // By default, subscriptions to transactional publications are synchronized 
                   // continuously, but in this case we only want to synchronize on demand.
                   subscription.AgentSchedule.FrequencyType = ScheduleFrequencyType.OnDemand;

                   // Create the push subscription.
                   subscription.Create();
               }
               else
               {
                   // Do something here if the publication does not exist.
                   throw new ApplicationException(String.Format(
                       "The publication '{0}' does not exist on {1}.",
                       publicationName, publisherName));
               }
           }
           catch (Exception ex)
           {
               // Implement the appropriate error handling here.
               throw new ApplicationException(String.Format(
                   "The subscription to {0} could not be created.", publicationName), ex);
           }
           finally
           {
               conn.Disconnect();
           }

Remarks

SubscriptionDBName is a required property and must be set before the subscription is created on the server. Once the subscription registration exists on the server, the SubscriptionDBName property cannot be changed.

The SubscriptionDBName property can only be retrieved 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.

The SubscriptionDBName property can only be set 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.

Retrieving the SubscriptionDBName property is equivalent to executing sp_helpsubscription or sp_helpmergesubscription.

Setting the SubscriptionDBName property is equivalent to executing sp_addsubscription or sp_addmergesubscription.
