Restore Database "Restore failed for Server 'xxx' "

StackOverflow https://stackoverflow.com/questions/14813523

Question

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

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 : All exception message is just this : enter image description here

Thanks For your advice....

Solution

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.

The C# code is : 

    /// <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>
    /// <param name="UserName">user name</param>
    /// <param name="Password">password</param>
