SyncTable.SyncDirection 属性

获取或设置 SyncDirection 枚举值，该值表示相对于客户端的同步方向。

命名空间: Microsoft.Synchronization.Data
程序集: Microsoft.Synchronization.Data（在 microsoft.synchronization.data.dll 中）

语法

声明
Public Property SyncDirection As SyncDirection
用法
Dim instance As SyncTable
Dim value As SyncDirection

value = instance.SyncDirection

instance.SyncDirection = value

public SyncDirection SyncDirection { get; set; }

public:
property SyncDirection SyncDirection {
    SyncDirection get ();
    void set (SyncDirection value);
}

/** @property */
public SyncDirection get_SyncDirection ()

/** @property */
public void set_SyncDirection (SyncDirection value)

public function get SyncDirection () : SyncDirection

public function set SyncDirection (value : SyncDirection)

属性值

一个 SyncDirection 枚举值，表示相对于客户端的同步方向。

备注

同步方向确定同步期间在客户端和服务器数据库之间交换变更的方式。有关更多信息，请参见如何指定快照同步、下载同步、上载同步和双向同步。

示例

下面的代码示例摘自从 SyncAgent 派生的类。代码创建两个同步组和三个同步表。Customer 表添加到 Customer 组，OrderHeader 和 OrderDetail 表添加到 Order 组。所有表都仅限下载。如果某个表在客户端存在，则会在初始同步期间删除并重新创建该表。若要在完整示例上下文中查看此代码，请参见如何筛选行和列。

//Create two SyncGroups so that changes to OrderHeader
//and OrderDetail are made in one transaction. Depending on
//application requirements, you might include Customer
//in the same group.
SyncGroup customerSyncGroup = new SyncGroup("Customer");
SyncGroup orderSyncGroup = new SyncGroup("Order");

//Add each table: specify a synchronization direction of
//DownloadOnly.
SyncTable customerSyncTable = new SyncTable("Customer");
customerSyncTable.CreationOption = TableCreationOption.DropExistingOrCreateNewTable;
customerSyncTable.SyncDirection = SyncDirection.DownloadOnly;
customerSyncTable.SyncGroup = customerSyncGroup;
this.Configuration.SyncTables.Add(customerSyncTable);

SyncTable orderHeaderSyncTable = new SyncTable("OrderHeader");
