如何同步订阅（以编程方式）

项目
05/21/2007

本主题将介绍如何使用 SqlCeReplication 类同步 Microsoft SQL Server 2005 Compact Edition (SQL Server Compact Edition) 中的订阅。有关使用 SqlServerCe 命名空间的详细信息，请参阅 SqlServerCe 命名空间参考文档。

过程标题

初始化 SqlCeReplication 对象。

SqlCeReplication repl = new SqlCeReplication();

设置连接属性。这些属性指定所订阅发布的名称和位置、本地 SQL Server Compact Edition 数据库的名称和位置以及 SQL Server Compact Edition 服务器代理的位置。

repl.InternetUrl = "https://www.adventure-works.com/sqlmobile/sqlcesa30.dll";
repl.InternetLogin = "MyInternetLogin";
repl.InternetPassword = "<password>";
repl.Publisher = "MyPublisher";
repl.PublisherDatabase = "MyPublisherDatabase";
repl.PublisherLogin = "MyPublisherLogin";
repl.PublisherPassword = "<password>";
repl.Publication = "MyPublication";
repl.Subscriber = "MySubscriber";
repl.SubscriberConnectionString = "Data Source=MyDatabase.sdf";

调用 AddSubscription 方法创建订阅。

repl.AddSubscription(AddOption.CreateDatabase);

调用 Synchronize 方法执行数据同步，并用发布中的数据填充本地数据库。
```
repl.Synchronize();
```

示例

本示例说明如何创建订阅并与 Microsoft SQL Server 同步数据。在此示例中，本地数据库的名称为 MyDatabase.sdf，发布的名称为 MyPublication。

SqlCeReplication repl = null;

        try
        {
            // Create an instance of and configure the SqlCeReplication object
            //
            repl = new SqlCeReplication();
            repl.InternetUrl = "https://www.adventure-works.com/sqlmobile/sqlcesa30.dll";
            repl.InternetLogin = "MyInternetLogin";
            repl.InternetPassword = "<password>";
            repl.Publisher = "MyPublisher";
            repl.PublisherDatabase = "MyPublisherDatabase";
            repl.PublisherLogin = "MyPublisherLogin";
            repl.PublisherPassword = "<password>";
            repl.Publication = "MyPublication";
            repl.Subscriber = "MySubscriber";
            repl.SubscriberConnectionString = "Data Source=MyDatabase.sdf";

            // Create a local SQL Server Compact Edition Database subscription
            //
            repl.AddSubscription(AddOption.CreateDatabase);

            // Synchronize to the SQL Server database
            //
            repl.Synchronize();
        }
        catch (SqlCeException)
        {
            // Handle errors here
            //
        }
        finally
        {
            // Dispose the repl object
            //
            repl.Dispose();
        }
