我正在尝试使用 RMO 以编程方式执行合并同步。我基本上复制了SQL Server示例代码，如下：
// Create a connection to the Subscriber.
ServerConnection conn = new ServerConnection(subscriberName);
MergePullSubscription subscription;
try
{
// Connect to the Subscriber.
conn.Connect();
// Define the pull subscription.
subscription = new MergePullSubscription(subscriptionDbName, publisherName, publicationDbName,
publicationName, conn, false);
// If the pull subscription exists, then start the synchronization.
if (subscription.LoadProperties())
{
// Check that we have enough metadata to start the agent.
if (subscription.PublisherSecurity != null || subscription.DistributorSecurity != null)
{
subscription.SynchronizationAgent.Synchronize();
}
else
{
throw new ApplicationException("There is insufficent metadata to " +
"synchronize the subscription. Recreate the subscription with " +
"the agent job or supply the required agent properties at run time.");
}
}
else
{
// Do something here if the pull subscription does not exist.
throw new ApplicationException(String.Format(
"A subscription to '{0}' does not exist on {1}",
publicationName, subscriberName));
}
}
catch (Exception ex)
{
// Implement appropriate error handling here.
throw new ApplicationException("The subscription could not be " +
"synchronized. Verify that the subscription has " +
"been defined correctly.", ex);
}
finally
{
conn.Disconnect();
}
我已经正确定义了服务器合并发布，但是当我运行上面的代码时，我在调用时得到一个空引用异常：
subscription.SynchronizationAgent.Synchronize();
堆栈跟踪如下：
at Microsoft.SqlServer.Replication.MergeSynchronizationAgent.StatusEventSinkMethod(String message, Int32 percent, Int32* returnValue)
at Test.ConsoleTest.Program.SynchronizePullSubscription() in F:\Visual Studio Projects\Test\source\Test.ConsoleTest\Program.cs:line 124
从堆栈跟踪来看，似乎与 Status 事件有关，但我没有定义处理程序，定义一个处理程序没有区别。
