範例：從現有記錄初始化一項記錄
發行︰ 2017年1月
適用於： Dynamics 365 (online)、Dynamics 365 (on-premises)、Dynamics CRM 2016、Dynamics CRM Online
這個範例程式碼適用於 Microsoft Dynamics 365 (線上和內部部署)。下載 Microsoft Dynamics CRM SDK 套件。 可以在下列位置的下載套件中找到：

如需執行此 SDK 所提供範例程式碼的需求資訊，請參閱使用範例和 Helper 程式碼。
- 完整範例 – C#
示範
此範例顯示如何使用 IOrganizationService.InitializeFromRequest 訊息來從現存紀錄中建立新的紀錄。
