I made a program in c# that dump in mysql, it is very cool, it selects the bank and does the dump alone,making a sql file on my computer, and I just need to climb the bank later to where I wish.
HOWEVER I’m having a problem when it comes time to take the bank to the place where I wish, (pelo cmd: mysql -u root -p -hNome_do_local < banco.sql), it is giving accentuation errors. Opening the dump made by my system I found out that it is putting:
/*!40101 SET NAMES latin1 /; when it was meant to be: /!40101 SET NAMES utf8 */;
I tried to solve by putting this in my code:
Server=xxxxxxx;Port=xxxxx;Database=xxx;Uid=xxxxx;Pwd=xxxx;charset=utf8;"
and
mb.ImportInfo.DatabaseDefaultCharSet="utf8";
but he keeps making a file with latin1

I know there’s a lot on the show, but overall the problem is:

using (MySqlConnection cn = new MySqlConnection())

byte[] utf8Bytes = Encoding.UTF8.GetBytes("ASCII to UTF8");
byte[] isoBytes = Encoding.Convert(Encoding.ASCII, Encoding.UTF8, utf8Bytes);
string uf8converted = Encoding.UTF8.GetString(isoBytes);
using (MySqlCommand cmd = new MySqlCommand())
{
using (MySqlBackup mb = new MySqlBackup(cmd))
{
string fazendo = "fazendo backup";
MessageBox.Show(fazendo);
processo.Visible = true;
processo.Value = 10;
cmd.Connection = cn;
processo.Value = 20;
cn.Open();
processo.Value = 50;
processolab.Visible = true;
mb.ImportInfo.DatabaseDefaultCharSet ="utf8";
processo.Value = 65;
mb.ExportToFile(file);
processo.Value = 80;
cn.Close();
processo.Value = 90;
string startPath = caminho.Text + @"\Dumps\Arquivo_SQL";
string zipPath = caminho.Text + @"\Dumps\Arquivo_ZIP\" + comboBox1.Text + data + ".zip";
ZipFile.CreateFromDirectory(startPath, zipPath);
processo.Value = 100;
processolab.Visible = false;
}
}
}
}
MessageBox.Show("backup feito");
//if (File.Exists(caminho.Text + @"\Dumps\Arquivo_SQL\" + comboBox1.Text + data + ".sql"))//exclue sql

break;
case DialogResult.No:
break;
}
}
or in the:
private void button1_Click(object sender, EventArgs e)
{
string nomesever = (string)sever.Text;
string nomeuser = (string)user.Text;
string senha = (string)pass.Text;
try

if you have any questions about my code or the question itself, please ask me, but I need help with this problem.

Put in the full code so we can understand how it was implemented.
