DestinationCallbacks 屬性

在衍生類別中覆寫時，會取得用來分派同步處理事件的 SyncCallbacks 物件。

命名空間：  Microsoft.Synchronization.SimpleProviders
組件：  Microsoft.Synchronization.SimpleProviders (在 Microsoft.Synchronization.SimpleProviders.dll 中)

語法

'宣告
Public ReadOnly Property DestinationCallbacks As SyncCallbacks
    Get
'用途
Dim instance As SimpleSyncProvider
Dim value As SyncCallbacks

value = instance.DestinationCallbacks

public SyncCallbacks DestinationCallbacks { get; }

public:
virtual property SyncCallbacks^ DestinationCallbacks {
    SyncCallbacks^ get () sealed;
}

abstract DestinationCallbacks : SyncCallbacks

final function get DestinationCallbacks () : SyncCallbacks

屬性值

型別：Microsoft.Synchronization. . :: . .SyncCallbacks
用來分派同步處理事件的 SyncCallbacks 物件。

範例

下列程式碼範例會建立讓範例應用程式向主控台報告進度和狀態的事件處理常式。若要在完整應用程式的內容中檢視這段程式碼，請參閱 Sync Framework SDK 及 Code Gallery 中的 "Sync101 using Simple Sync Provider" 應用程式。
