这是msdn中的一个例子,把sql server中的选定数据保存到本地的数据库ssce.sdf中
string rdaOleDbConnectString = "Provider=sqloledb; Data Source=MySqlServer;Initial Catalog=Northwind; " +
"User Id=username;Password = <password>";
// Initialize RDA Object.
SqlCeRemoteDataAccess rda = null; try {
//Try the Pull Operation.
rda = new SqlCeRemoteDataAccess();
rda.InternetLogin = "MyLogin";
rda.InternetPassword = "<password>";
rda.InternetUrl = "<http://www.northwindtraders.com/sqlce/sscesa20.dll>";
rda.LocalConnectionString = @"Provider=Microsoft.SQLSERVER.OLEDB.CE.2.0;Data Source=\ssce.sdf";
rda.Pull(
"Employees",
"Select * from Employees",
rdaOleDbConnectString,
RdaTrackOption.TrackingOnWithIndexes ,
"ErrorTable");
}
catch(SqlCeException) {
//Use you own Error Handling Routine.
}
finally {
//Dispose of the RDA Object.
rda.Dispose();

} 这个是从本地数据库ssce.sdf传送回sqlserver
参考 SqlCeRemoteDataAccess类
我的程序都是操作本地数据库的,需要数据时用pull从连接的pc上的sqlserver中获得数据,对数据修改后再用push将修改后的数据传回,但是不能直接访问sqlserver,程序是在pda上执行的
