直接在cmd执行如下代码：

mysqldump  -h localhost -uroot -p123 --default-character-set=utf8 --opt --disable-keys --lock-all-tables -R --hex-blob  TEST >D:\PM\bin\Debug\BackUp\TEST_20161212.sqlTEST为数据库名称

// 执行创建数据库操作
this.GetExecute(G_Con, "create database if not exists NEWDB");this.sqlAddress = " -h " + IP + " -u" + User + " -p" + Password + " NEWDB ";
// 数据库的备份
private void btn_Dump_Click(object sender, EventArgs e)
{using (SaveFileDialog sfd = new SaveFileDialog()){sfd.Filter = "数据库文件|*.sql";sfd.FilterIndex = 0;sfd.RestoreDirectory = true;sfd.FileName = "BackUp" + DateTime.Now.ToString("yyyyMMddHHmmss") + ".sql";if (sfd.ShowDialog() == System.Windows.Forms.DialogResult.OK){string filePath = sfd.FileName;string cmd = "mysqldump " + sqlAddress + " > \"" + filePath + "\"";string result = RunCmd(cmd);if (result.Trim() == ""){MessageBox.Show("数据库备份成功!", "CMS", MessageBoxButtons.OK, MessageBoxIcon.Information);}else{MessageBox.Show(result, "CMS", MessageBoxButtons.OK, MessageBoxIcon.Information);}}}
}
//数据库的还原
// 还原数据库
private void btn_Import_Click(object sender, EventArgs e)
{if (this.tb_Path.Text.Trim() == ""){MessageBox.Show("请选择要恢复的文件!", "CMS", MessageBoxButtons.OK, MessageBoxIcon.Information);return; }//this.GetExecute(G_Con, "create database if not exists clothes");string filePath = this.tb_Path.Text.Trim();string cmd = "mysql " + sqlAddress + " < \"" + filePath + "\"";string result = RunCmd(cmd);if (result.Trim() == ""){MessageBox.Show("数据库恢复成功!", "CMS", MessageBoxButtons.OK, MessageBoxIcon.Information);}else{MessageBox.Show(result, "CMS", MessageBoxButtons.OK, MessageBoxIcon.Information);}
}
// 命令行操作
private string RunCmd(string command)
{//例ProcessProcess p = new Process();p.StartInfo.FileName = "cmd.exe";           //确定程序名p.StartInfo.Arguments = "/c " + command;    //确定程式命令行p.StartInfo.UseShellExecute = false;        //Shell的使用p.StartInfo.RedirectStandardInput = true;   //重定向输入p.StartInfo.RedirectStandardOutput = true; //重定向输出p.StartInfo.RedirectStandardError = true;   //重定向输出错误p.StartInfo.CreateNoWindow = true;          //设置置不显示示窗口p.Start();   //00
p.StandardInput.WriteLine(command);       //也可以用这种方式输入入要行的命令
p.StandardInput.WriteLine("exit");        //要得加上Exit要不然下一行程式//p.WaitForExit();//p.Close();//return p.StandardOutput.ReadToEnd();        //输出出流取得命令行结果果return p.StandardError.ReadToEnd();
