Hello,

i'm trying to get backup to mysql database. I used this code

private void button1_Click(object sender, EventArgs e)
{
    string Coonstring = "datasource=localhost;port=3306;username=****;password=****;Charset=utf8";
    MySqlConnection cn= new MySqlConnection(Coonstring);
    MySqlCommand cmd;
    SaveFileDialog sf = new SaveFileDialog();
    sf.Filter = "Backup Files (*.Bak) |*.bak";
    if(sf.ShowDialog()==DialogResult.OK)
    {
        cmd = new MySqlCommand("Backup Database project To Disk='" + sf.FileName + "'", cn);
        cn.Open();
        cmd.ExecuteNonQuery();
        MessageBox.Show("Done");
        cn.Close();
    }
}

but i get error ( An unhandled exception of type 'MySql.Data.MySqlClient.MySqlException' occurred in MySql.Data.dll

Additional information: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'Backup Database project To Disk='C:\Users\tariq emad\Desktop\1\tt.bak'' at line 1).

So, any one can help me to fix this error?
