FileInfo CopyTo Method Fails through mapped drive

Posted on 2006-06-16

I am trying to use the fileinfo copyto method to copy a file from a mapped drive to the local machine, when i run it, it breaks with a file not found exception, if i just hit continue after it breaks it then works fine. It seems that it is not waiting long enough to find the mapped drive?

code snippet:

FileInfo fi1 = new FileInfo( "J:\\BackUp-" + time.ToLongDateString().Remove( 0, time.ToLongDateString().IndexOf( " ", 0, 20 ) ).Trim().Replace( ",", "" ) + ".BAK" );

FileInfo fi2 = new FileInfo( saveBackupDialog.FileName );
fi1.CopyTo( fi2.Name, true );

I have tried inserting a pause like: System.Threading.Thread.Sleep( 5000 ); between the creation of the file and copying the file but that does not work. (The file is created just before it is copied)

Can you show the code where the file is created?

Can you also try using,

  fi1.CopyTo(fi2.FullName, true);


  fi1.CopyTo(saveBackupDialog.FileName, true);

i tried those and it did not work, here is more of the code

what this code does is have the sql server perform a backup to its local drive which i have mapped as the j drive from my dev machine and i hant to copy that file to my dev machine after the sql server performs the backup.

when i run the code it breaks on the copyto method with a filenotfoundexception and when i hit continue after it breaks it works fine

// Creates backup device
BackupDeviceItem bkpDevice = new BackupDeviceItem( "C:\\BackUps\\BackUp-" + time.ToLongDateString().Remove( 0, time.ToLongDateString().IndexOf( " ", 0, 20 ) ).Trim().Replace( ",", "" ) + ".BAK", DeviceType.File );

                    // Add the backup device to the backup
                    bkpDatabase.Devices.Add( bkpDevice );

                    // Perform the backup
                    bkpDatabase.PercentComplete += new PercentCompleteEventHandler( rstDatabase_PercentComplete );
                    bkpDatabase.SqlBackup( srvSql );
                    bkpDatabase.PercentComplete -= rstDatabase_PercentComplete;

                    FileInfo fi1 = new FileInfo( "J:\\BackUp-" + time.ToLongDateString().Remove( 0, time.ToLongDateString().IndexOf( " ", 0, 20 ) ).Trim().Replace( ",", "" ) + ".BAK" );

                    FileInfo fi2 = new FileInfo( saveBackupDialog.FileName );
                    fi1.CopyTo( fi2.FullName, true );
                    toolStripStatusLabel1.Text = "Back-Up Successful";

You could try this:

  while (!fi1.Exists)

  fi1.CopyTo( fi2.FullName, true );

That works perfectly, also i did a check with an int and it runs through that loop 18 times before it finds the file
