    RecoverableErrorData errorData
)

public:

示例

下面的代码示例演示 DeleteItem 方法的实现，该方法将删除应用于内存中的示例数据存储区。如果无法应用删除，则此方法记录一个可恢复错误。若要在完整应用程序的上下文中查看此代码，请参见"Sync101 using Simple Sync Provider" 应用程序（可从 Sync Framework SDK 和 Code Gallery 获得）。

public override void DeleteItem(ItemFieldDictionary keyAndExpectedVersion, 
    RecoverableErrorReportingContext recoverableErrorReportingContext, 
    out bool commitKnowledgeAfterThisItem)
{
    IDictionary<uint, ItemField> expectedFields = (IDictionary<uint, ItemField>)keyAndExpectedVersion;
    ulong id = (ulong)expectedFields[CUSTOM_FIELD_ID].Value;
    if (_store.Contains(id))
    {
        _store.DeleteItem(id);
    }
    else
    {
        // If the item to delete does not exist, record an error on this change and 
        // continue with the rest of the session.
        recoverableErrorReportingContext.RecordRecoverableErrorForChange(new RecoverableErrorData(new Exception("Item not found in the store")));
    }
    commitKnowledgeAfterThisItem = false;
}

Public Overrides Sub DeleteItem(ByVal keyAndExpectedVersion As ItemFieldDictionary, ByVal recoverableErrorReportingContext As RecoverableErrorReportingContext, ByRef commitKnowledgeAfterThisItem As Boolean)
    Dim expectedFields As IDictionary(Of UInteger, ItemField) = DirectCast(keyAndExpectedVersion, IDictionary(Of UInteger, ItemField))
    Dim id As ULong = CULng(expectedFields(CUSTOM_FIELD_ID).Value)
    If _store.Contains(id) Then
        _store.DeleteItem(id)
    Else
        ' If the item to delete does not exist, record an error on this change and 
        ' continue with the rest of the session. 
        recoverableErrorReportingContext.RecordRecoverableErrorForChange(New RecoverableErrorData(New Exception("Item not found in the store")))
    End If
    commitKnowledgeAfterThisItem = False
End Sub
