SqlCeReplication.SaveProperties 方法
检索存储在当前订阅的 SqlCeReplication 类属性中的所有值,并将它们存储在系统表中。
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 SaveProperties
用法
Dim instance As SqlCeReplication
instance.SaveProperties
public void SaveProperties ()
public:
void SaveProperties ()
public void SaveProperties ()
public function SaveProperties ()
不适用。
备注
必须在保存同步属性之前成功创建订阅;若要成功调用 SaveProperties,必须提供运行同步所必需的所有参数。如果在保存同步属性时省略了非必需参数,那么,即使已经存在保存的同步属性,这些非必需参数也会设置为默认值。若要避免改写属性,用户应首先检索同步属性,方法是:调用 LoadProperties,更改特定的属性,然后重新保存同步属性。
调用 SaveProperties 时,密码属性的值存储在数据库中。这些值将自动使用唯一的设备硬件密钥进行加密。因此,如果您在一个设备(或一个服务器)上创建订阅配置文件,然后将该数据库复制到一个新设备上,则 LoadProperties 将无法从配置文件检索密码。您可以手动提供正确的密码,然后再次调用 SaveProperties 以保留新设备上的配置文件。
示例
下面的示例显示如何使用 SaveProperties 方法。
Dim repl As SqlCeReplication = Nothing
Try
' Create SqlCeReplication instance
'
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"
' Store all the properties in the database
'
repl.SaveProperties()
' In the future all you need to do is load the properties
'
repl = New SqlCeReplication()
repl.SubscriberConnectionString = "Data Source='Test.sdf'; Pwd='<password>'"
repl.LoadProperties()
' Now the SqlCeReplication instance is ready to sync
'
repl.Synchronize()
Catch
' Handle errors here
Finally
' Dispose the repl object
'
repl.Dispose()
End Try
SqlCeReplication repl = null;
try
{
// Create SqlCeReplication instance
//
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";
// Store all the properties in the database
//
repl.SaveProperties();
// In the future all you need to do is load the properties
//
repl = new SqlCeReplication();
repl.SubscriberConnectionString = "Data Source='Test.sdf'; Pwd='<password>'";
repl.LoadProperties();
// Now the SqlCeReplication instance is ready to sync
//
repl.Synchronize();
}
catch (SqlCeException)
{
// Handle errors here
}
finally
{
// Dispose the repl object
//
repl.Dispose();
}
