how to take backup of the MYSQL database in C#.NET

DateTime backupTime = DateTime.Now;
                   int year = backupTime.Year;
                   int month = backupTime.Month;
                   int day = backupTime.Day;
                   int hour = backupTime.Hour;
                   int minute = backupTime.Minute;
                   int second = backupTime.Second;
                   int ms = backupTime.Millisecond;

                   String tmestr = backupTime.ToString();
                   tmestr = "C:\\" + year + "-" + month + "-" + day + "-" + hour + "-" + minute + ".sql";
                   StreamWriter file = new StreamWriter(tmestr);
                   ProcessStartInfo proc = new ProcessStartInfo();
                   string cmd = string.Format(@"-u {0} -p {1} -h {2}  {3} >  {4};", "root", "", "localhost", "globasys", "backup.sql");
                   proc.FileName = @"C:\Program Files\MySQL\MySQL Server 6.0\bin\mysqldump";
                   proc.RedirectStandardInput = false;
                   proc.RedirectStandardOutput = true;
                   proc.Arguments = cmd;//"-u root -p smartdb > testdb.sql";
                   proc.UseShellExecute = false;
                   Process p = Process.Start(proc);
                   string res;
                   res = p.StandardOutput.ReadToEnd();
                   file.WriteLine(res);
                   p.WaitForExit();
                   file.Close();
