Need help connection with Microsoft.SqlServer.Management.Smo Transfer class

Question

I am trying to copy everything (data, indexes, triggers, stored procedure). From one database to another in C#.

Here is my code:

SqlConnection connection = new SqlConnection(ConnectionString);

Server myServer = new Server(new ServerConnection(connection));               

Database db = myServer.Databases[this._myDB];

if (myServer.Databases[this._newDB] != null)
   myServer.Databases[this._newDB].Drop();

Database newdb = new Database(myServer, this._newDB);
newdb.Create();

Transfer transfer = new Transfer(db);
transfer.CopyAllSchemas = false;
transfer.CopyAllStoredProcedures = true;
transfer.CopyAllTables = true;
transfer.CopyAllDatabaseTriggers = true;
transfer.CopyAllObjects = true;
transfer.CopyAllUsers = true;
transfer.Options.WithDependencies = true;
transfer.DestinationDatabase = newdb.Name;
transfer.DestinationServer = myServer.Name;
transfer.DestinationLoginSecure = false;
transfer.DestinationLogin = user;
transfer.DestinationPassword = pwd;
transfer.CopySchema = false;
transfer.CopyData = true;
transfer.Options.DriAll = true;
transfer.Options.Triggers = true;
transfer.Options.WithDependencies = true;
transfer.Options.ContinueScriptingOnError = true;

transfer.TransferData();

I get the following error:

errorCode=-1071636471 description=SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005.
An OLE DB record is available. Source: "Microsoft SQL Server Native Client 10.0" Hresult: 0x80004005 Description: "Login failed for user 'DOMAIN\user'.".

helpFile= helpContext=0 idofInterfaceWithError={5BC870EB-BBA5-4B9D-A6E3-58C6D0051F14}

The closest I have come to accomplishing it with a workaround is by doing:

script = transfer.ScriptTransfer();

foreach (string s in script)
{
     //run a sqlcommand for s
}

But this doesn't get the data.

I have given the user every permission I can think of both for SQL Server and for the database itself.

Its too late but it could help some body else,

I had the same problem and its due to the first line, the cast to the SqlConnection. It activates the mixed authentication [thats why you got an error as your login is wrong for 'DOMAIN\user']

I've choose to initialize a simple connection using the SqlConnectionStringBuilder:

var connectionString = ((EntityConnection)base.ReferentielContext.Connection).StoreConnection.ConnectionString;
var builder = new SqlConnectionStringBuilder(connectionString);

var srvConn = new ServerConnection
        {
            ServerInstance = builder.DataSource,
            LoginSecure = false,// set to true for Windows Authentication
            Login = builder.UserID,
            Password = builder.Password
        };

var server = new Microsoft.SqlServer.Management.Smo.Server(srvConn);
