// Define server, publication, and database names.

String publisherName = publisherInstance;
String publicationName = "AdvWorksSalesOrdersMerge";

// Create a connection to the Subscriber.

注解

MergeSynchronizationAgent使用 属性返回SynchronizationAgent的 对象同步启动合并代理。

如果请求订阅的创建值为 falseCreateSyncAgentByDefault，则默认情况下，不会为订阅创建合并代理作业，调用 SynchronizeWithJob 将导致异常。

StopSynchronizationJob调用 方法以停止作业（如果作业当前正在运行）。

如果 Microsoft SQL Server 代理服务未运行，则作业无法启动。 此外，如果未生成快照，则运行代理作业可能不会同步订阅。

如果已在此 实例 MergePullSubscription上设置了其他属性，请在调用 之前调用 CommitPropertyChangesSynchronizeWithJob。

方法 SynchronizeWithJob 只能由订阅服务器上的 sysadmin 固定服务器角色的成员或订阅数据库中 db_owner 固定数据库角色的成员调用。
