SyncAgent 類別

SyncAgent 物件會協調同步處理。

命名空間: Microsoft.Synchronization
組件: Microsoft.Synchronization.Data (在 microsoft.synchronization.data.dll)

語法

'宣告
Public Class SyncAgent
    Implements IDisposable
'用途
Dim instance As SyncAgent
public class SyncAgent : IDisposable
public ref class SyncAgent : IDisposable
public class SyncAgent implements IDisposable
public class SyncAgent implements IDisposable

備註

SyncAgent 會在每個要同步處理的資料表中執行迴圈,並且呼叫用戶端同步處理提供者 (Provider),以便在用戶端資料庫上擷取並套用變更。然後,它會呼叫伺服器同步處理提供者,以便在伺服器資料庫上擷取並套用變更。

範例

下列程式碼範例會建立衍生自 SyncAgent 的類別 (Class)。此類別會具現化用戶端同步處理提供者和伺服器同步處理提供者、建立同步處理群組,並且加入 Customer 資料表。加入此資料表時,也會一併指定同步處理方向和資料表建立選項。若要在完整範例的內容中檢視這段程式碼,請參閱 HOW TO:交換用戶端和伺服器之間的雙向增量資料變更
