C#Winform使用mysql作为本地数据库

MYSQL是老牌关系型数据库，在受够了sqlite，mslocaldb，sqlce等本地数据库之后，发现了mysql5.6的一些版本也可以绿色安装，编程实现从资源文件里面解压到目标机器上，并配置好成为本机系统服务。并且EF的mysql驱动对code first支持非常好。于是探索出了用mysql来做本地数据库的方法。

my.ini配置

[client]

[mysqld]

basedir="%BaseDir%"
datadir="%BaseDir%data/"
character-set-server=gbk
default-storage-engine=MyISAM
sql-mode="NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"
max_connections=512

table_cache=256
tmp_table_size=18M

thread_cache_size=8
myisam_max_sort_file_size=64G
myisam_sort_buffer_size=35M
key_buffer_size=25M
read_buffer_size=256K
read_rnd_buffer_size=64M
sort_buffer_size=256M

innodb_additional_mem_pool_size=24M

innodb_log_buffer_size=12M

innodb_buffer_pool_size=47M
