ReinitializeSubscription 方法

标记需要重新初始化的订阅。调用此方法后，应用程序必须调用 Synchronize 方法来将发布内容的最新快照下载到设备上。

命名空间：  System.Data.SqlServerCe
程序集：  System.Data.SqlServerCe（在 System.Data.SqlServerCe.dll 中）

语法

声明
Public Sub ReinitializeSubscription ( _
    uploadBeforeReinitialize As Boolean _
)
用法
Dim instance As SqlCeReplication
Dim uploadBeforeReinitialize As Boolean

instance.ReinitializeSubscription(uploadBeforeReinitialize)

public void ReinitializeSubscription(
    bool uploadBeforeReinitialize
)

public:
void ReinitializeSubscription(
    bool uploadBeforeReinitialize
)

member ReinitializeSubscription : 
        uploadBeforeReinitialize:bool -> unit 

public function ReinitializeSubscription(
    uploadBeforeReinitialize : boolean
)

参数

• uploadBeforeReinitialize
  类型：System. . :: . .Boolean
  如果值为 True，在订阅服务器上应用快照之前订阅数据库中的更改将上载到发布服务器上。默认为 False。

注释

将在 SQL Server Compact 3.5 订阅系统表中设置一个标志，指示该订阅应在下次同步过程中重新进行初始化。调用 ReinitializeSubscription 方法后，应用程序必须调用 Synchronize 方法删除现有副本，并将新的发布副本下载到基于 Windows Mobile 的设备上。

示例

Dim repl As SqlCeReplication = Nothing

Try
    ' Create SqlCeReplication instance
    '
    'NOTE: when possible, prompt users to enter security 
    'credentials at runtime. If you store credentials in a file, 
    'you must secure the file to prevent unauthorized access.
    '
    repl = New SqlCeReplication()
    repl.InternetUrl = "https://www.adventure-works.com/sqlmobile/sqlcesa35.dll"
    repl.InternetLogin = "MyInternetLogin"
    repl.InternetPassword = "<enterStrongPassword>"
    repl.Publisher = "MyPublisher"
    repl.PublisherDatabase = "MyPublisherDatabase"
    repl.PublisherLogin = "MyPublisherLogin"
    repl.PublisherPassword = "<enterStrongPassword>"
    repl.Publication = "MyPublication"
    repl.Subscriber = "MySubscriber"
    repl.SubscriberConnectionString = "Data Source=MyDatabase.sdf"

    ' Mark the subscription for reinitialization with Upload first
    '
    repl.ReinitializeSubscription(True)

    ' Synchronize to the SQL Server to populate the Subscription 
    '
    repl.Synchronize()
Catch
    ' Handle errors here
Finally
    ' Dispose the repl object
    '
    repl.Dispose()
End Try

SqlCeReplication repl = null;

try
{
    // Create SqlCeReplication instance
    //
    //NOTE: when possible, prompt users to enter security 
    //credentials at runtime. If you store credentials in a file, 
    //you must secure the file to prevent unauthorized access.
    //
    repl = new SqlCeReplication();
    repl.InternetUrl = "https://www.adventure-works.com/sqlmobile/sqlcesa35.dll";
    repl.InternetLogin = "MyInternetLogin";
    repl.InternetPassword = "<enterStrongPassword>";
    repl.Publisher = "MyPublisher";
    repl.PublisherDatabase = "MyPublisherDatabase";
    repl.PublisherLogin = "MyPublisherLogin";
    repl.PublisherPassword = "<enterStrongPassword>";
    repl.Publication = "MyPublication";
    repl.Subscriber = "MySubscriber";
    repl.SubscriberConnectionString = "Data Source=MyDatabase.sdf";

    // Mark the subscription for reinitialization with Upload first
    //
    repl.ReinitializeSubscription(true);

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