ApplyChangeFailed不衝突

Question

解僱我試圖從這裏Synchronizing SQL Server and SQL Express以下Microsoft例子，基本同步爲我工作同步兩個SQL Server數據塊。 現在，我試圖通過將兩個數據庫上的同一行更改爲不同的值來創建衝突，但是當我運行我的同步過程時，ApplyChangeFailed未被觸發。

我看過這個問題Microsoft Sync Framework Conflict Event does not fire但我不明白爲什麼當我同步客戶端< - >服務器配置時，框架會忽略衝突。

這裏是我的代碼，僅供參考，我有一個遠程SQL 2008 R2 Server作爲服務器和本地SQL 2012 Express作爲客戶端：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Data.SqlClient; 
using Microsoft.Synchronization; 
using Microsoft.Synchronization.Data; 
using Microsoft.Synchronization.Data.SqlServer; 
using Microsoft.Synchronization.Data.SqlServerCe; 

namespace ExecuteExpressSync 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      SqlConnection clientConn = new SqlConnection(@"Data Source=.\SQLEXPRESS; Initial Catalog=SyncExpressDB; Trusted_Connection=Yes"); 
      SqlConnection serverConn = new SqlConnection("Data Source=X.Y.Z.W; Initial Catalog=SyncDB; uid=sa;password=******;Integrated Security=False"); 

      // create the sync orhcestrator 
      SyncOrchestrator syncOrchestrator = new SyncOrchestrator(); 

      // set local provider of orchestrator to a sync provider associated with the 
      // ProductsScope in the SyncExpressDB express client database 
      syncOrchestrator.LocalProvider = new SqlSyncProvider("ProductsScope", clientConn); 

      // set the remote provider of orchestrator to a server sync provider associated with 
      // the ProductsScope in the SyncDB server database 
      syncOrchestrator.RemoteProvider = new SqlSyncProvider("ProductsScope", serverConn); 

      // set the direction of sync session to Upload and Download 
      syncOrchestrator.Direction = SyncDirectionOrder.UploadAndDownload; 

      // subscribe for errors that occur when applying changes to the client 
      ((SqlSyncProvider)syncOrchestrator.LocalProvider).ApplyChangeFailed += new EventHandler<DbApplyChangeFailedEventArgs>(Program_ApplyChangeFailed); 

      // execute the synchronization process 
      SyncOperationStatistics syncStats = syncOrchestrator.Synchronize(); 

      // print statistics 
      Console.WriteLine("Start Time: " + syncStats.SyncStartTime); 
      Console.WriteLine("Total Changes Uploaded: " + syncStats.UploadChangesTotal); 
      Console.WriteLine("Total Changes Downloaded: " + syncStats.DownloadChangesTotal); 
      Console.WriteLine("Complete Time: " + syncStats.SyncEndTime); 
      Console.WriteLine(String.Empty); 
     } 

     static void Program_ApplyChangeFailed(object sender, DbApplyChangeFailedEventArgs e) 
     { 
      // display conflict type 
      Console.WriteLine(e.Conflict.Type); 

      // display error message 
      Console.WriteLine(e.Error); 
     } 
    } 
} 

Answer 1

由於@JuneT指出該行缺少：

// subscribe for errors that occur when applying changes to the client 
((SqlSyncProvider)syncOrchestrator.RemoteProvider).ApplyChangeFailed += new EventHandler<DbApplyChangeFailedEventArgs>(Program_ApplyChangeFailed);
