问题描述
我有一个问题。我试着像belov的代码。但我得到例外。并且例外是：
I have a problem. I tried the code like belov. But i am getting exception. and the exception is :
"Restore failed for Server 'SMART0090\SQL2008RR2'." FailedOperationException. .... the error is at "restore.SqlRestore(server);" line
你对这个问题有什么看法？代码是：
What do you think about the problem? The code is :
public void RestoreToDatabase(string NewDatabaseName, string BackUpFile, string ServerName, string UserName, string Password)
{
ServerConnection connection = new ServerConnection(ServerName, UserName, Password);
Server sqlServer = new Server(connection);
Microsoft.SqlServer.Management.Smo.Server server = new Microsoft.SqlServer.Management.Smo.Server(connection);
Database database = new Database(server, NewDatabaseName);
database.Create();
database.Refresh();
Restore restore = new Restore();
restore.NoRecovery = false;
restore.Action = RestoreActionType.Database;
BackupDeviceItem bdi = default(BackupDeviceItem);
bdi = new BackupDeviceItem(BackUpFile, DeviceType.File);
restore.Devices.Add(bdi);
restore.Database = NewDatabaseName;
restore.ReplaceDatabase = true;
restore.PercentCompleteNotification = 10;
restore.SqlRestore(server);
database.Refresh();
database.SetOnline();
server.Refresh();
}
EDIT：所有异常消息都是这样：
EDIT : All exception message is just this :
感谢您的意见....
Thanks For your advice....
推荐答案
最后我找到了一个解决方案。错误是：当您还原* .bak文件时，* .mdf和* .ldf文件将复制到特殊目录。例如：当我还原一个* .bak文件我的* .mdf和* .ldf文件复制在C：\Program Files \Microsoft SQL Server \MSSQL10_50.SQL2008RR2 \MSSQL\DATA \。所以：如果同名的* .mdf或* .ldf文件，你可以得到异常像我一样。我解决它与更改* .mdf和* .ldf文件路径。我写belov代码，它的工作。
Finally I found a solution. The error is : when you restore a *.bak file, the *.mdf and *.ldf files are copied to a special directory. Forexample : when I restore a *.bak file my *.mdf and *.ldf files copied under "C:\Program Files\Microsoft SQL Server\MSSQL10_50.SQL2008RR2\MSSQL\DATA\". So : If there is same name for *.mdf or *.ldf file, you can get exception like i did. And I solve it with change *.mdf and *.ldf files path. I write belov code and it's working.
C＃代码是：
/// <summary>
/// Var olan backup ın restore edilmesini sağlar
/// </summary>
/// <param name="NewDatabaseName">new database name</param>
/// <param name="BackUpFile">backup file path</param>
/// <param name="ServerName">server name</param>
