How to realize MySQL Command Line backup and recovery by C #

This article is about how C # implements MySQL command line backup and recovery. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

There are many tools available for the backup of MySQL database. In the past two days, we have written a gadget to complete the backup and recovery of MySQL database by calling the mysqldump command of MYSQL with C #.

First, let's talk about how to use the mysqldump command to back up the MySQL database.

Mysqldump-hhostname-uusername-ppassword databasename > backupfile.sql

Compress backup of MySQL database directly

Mysqldump-hhostname-uusername-ppassword databasename | gzip > backupfile.sql.gz

Back up some table (s) in the MySQL database

Mysqldump-hhostname-uusername-ppassword databasename specific_table1 specific_table2 > backupfile.sql

Backup multiple MySQL databases at the same time

Mysqldump-hhostname-uusername-ppassword-databases databasename1 databasename2 databasename3 > multibackupfile.sql

Just back up the database structure

Mysqldump-no-data-databases databasename1 databasename2 databasename3 > structurebackupfile.sql

Back up all databases on the server

Mysqldump-all-databases > allbackupfile.sql

Commands for restoring MySQL databases

Mysql-hhostname-uusername-ppassword databasename < backupfile.sql

Restore a compressed MySQL database

Gunzip < backupfile.sql.gz | mysql-uusername-ppassword databasename

Transfer the database to a new server

Mysqldump-uusername-ppassword databasename | mysql-host=*.*-C databasename

Using C # to operate MYSQL backup and recovery, mainly using C # to execute external programs to achieve

The following is part of the C # source code

/ / back up the database to a specific directory / Bin folder directory to get the mysqldump.exe file / / server / / user name / / password / / the name of the database to be backed up / public static bool BackupDB (string binfolderpath, string server, string character, string user, string pass, string db String backupfile) {string command = string.Format ("mysqldump.exe-- quick-- host=\" {0}\ "- default-character-set=\" {1}\ "--lock-tables-- verbose-- force-- port=3306-- user=\" {2}\ "- password=\" {3}\ "- r\" {5}\ ", server, character.Trim (). ToLower (), user, pass, db, backupfile) StartCmd (binfolderpath + @ "\", command); if (File.Exists (backupfile)) {return true;} else {return false } / restore the specified database to the specified file / Bin folder directory to get the mysqldump.exe file / / server / / user name / / password / / database name to be backed up / SQL file / public static bool RestoreDB to be restored (string binfolderpath, string character, string server, string user, string pass, string db) String restorefile) {string command = string.Format ("mysql.exe-host=\" {0}\ "- default-character-set=\" {1}\ "- port=3306-- user=\" {2}\ "- password=\" {3}\ "\" {4}\ "
