c# Process 执行完回调 Proc_OutputDataReceived
mysql mysqldump mysql source备份还原数据
直接贴代码
前提：mysql5.7
vs2017 3.5
mysql文件夹 C:\Program Files\MySQL\MySQL Server 5.7\bin
备份文件夹 D:\Backup\2018\201812\20181217
还原：
备份：
直接上代码

已测试
有疑问可联系QQ 1023360745 仅供技术交流 骚扰不回。
建议先备份再还原
注意：还原会锁表 自己查看SQL
查询数据条数 自己根据自己的mysql 查询一下
我的场景：
备份数据：window服务中 一段代码 来自己备份数据
还原数据：client发送请求则还原需要查询的数据表 回调告诉client还原成功数据已ready！
