BulkInsertTask.TableLock 属性
定义
重要
一些信息与预发行产品相关，相应产品在发行之前可能会进行重大修改。 对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。
获得或设置一个布尔值，指示在批量插入操作期间表是否被锁定。
public:
property bool TableLock { bool get(); void set(bool value); };public bool TableLock { get; set; }member this.TableLock : bool with get, setPublic Property TableLock As Boolean属性值
如果你想在批量插入时锁定桌面，则为真;如果你不想锁定，那就是假。
实现
示例
以下示例创建 ，BulkInsertTask然后通过使用该 TaskHost，展示了属性的默认设置，包括 TableLock。 示例随后设置两个字段，演示如何设置字段值。
