範例
下列程式碼範例示範 InsertItem 方法的實作,此方法會將插入套用到記憶體中的範例資料存放區。如果無法套用插入,這個方法便會記錄條件約束錯誤。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。
public override void InsertItem(object itemData,
IEnumerable<SyncId> changeUnitsToCreate,

out ItemFieldDictionary keyAndUpdatedVersion,
out bool commitKnowledgeAfterThisItem)
{
ItemTransfer transfer = (ItemTransfer)itemData;
ItemData dataCopy = new ItemData(transfer.ItemData);
// Check for duplicates, and record a constraint error if a duplicate is detected.
if (!_store.Contains(transfer.Id))
{
_store.CreateItem(dataCopy, transfer.Id);
keyAndUpdatedVersion = _store.CreateItemFieldDictionary(transfer.Id);
}
