StopAllProcess()

Running your source code reveals that StopAllProcess() is called multiple times, but Command?.Cancel() throws a null reference exception.

fix advice：
public void StopAllProcess()
{
stopProcess = true;
if (Command != null)
{
try
{
Command.Cancel();
}
catch
{
// Ignore any errors in cleanup
}
}
timerReport?.Stop();

Another issue is that during the backup and restore process, this library can be interfered with by Navicat's refresh operation, resulting in incomplete restoration.

I'd like to know the maximum size of the SQL file your database supports for backup and restore,thank you very much.

Hi, thanks for the report. I'll try to have a look into it. Regarding your question about the max size this library can support. The library itself does not impose any limitation. If there is any limitation, it will be from the MySQL server that it is connecting with. Or there are other hidden limitation of the software environment that you are running, such as web request time-out, software UI timeout. But if you run this in a background thread/task, it will run on another thread which is not on the main UI thread, this will unlock the timeout issues. But anyway, even with running on 32bit process, the library processes things by chunk, so it should be ok to process any length of database size.

I hope your library gets better and better, more complete and stronger. Best wishes, buddy!
