连lian接jiemysql数shu据ju库ku的de方fang法fa及ji示shi例li
方fang法fa一yi：
使shi用yongMYSQL推tui出chu的deMySQL Connector/Net is an ADO.NET driver for MySQL
该gai组zu件jian为weiMYSQL为weiADO.NET访fang问wenMYSQL数shu据ju库ku设she计ji的de.NET访fang问wen组zu件jian。
安an装zhuang完wan成cheng该gai组zu件jian后hou，引yin用yong命ming名ming空kong间jianMySql.Data.MySqlClient;
使shi用yong命ming令ling行xing编bian译yi时shi：csc /r:MySql.Data.dll test.cs
方fang法fa二er：
通tong过guoODBC访fang问wenMYSQL数shu据ju库ku
访fang问wen前qian要yao先xian下xia载zai两liang个ge组zu件jian：odbc.net和heMYSQL的deODBC驱qu动dong(MySQL Connector/ODBC (MyODBC) driver)目mu前qian为wei3.51版ban
安an装zhuang完wan成cheng后hou，即ji可ke通tong过guoODBC访fang问wenMYSQL数shu据ju库ku
方fang法fa三san：
使shi用yongCoreLab推tui出chu的deMYSQL访fang问wen组zu件jian，面mian向xiang.NET
安an装zhuang完wan成cheng后hou，引yin用yong命ming名ming空kong间jian：CoreLab.MySql;
使shi用yong命ming令ling编bian译yi时shi：csc /r:CoreLab.MySql.dll test.cs以yi下xia为wei访fang问wenMYSQL数shu据ju库ku实shi例li编bian译yi指zhi令ling：csc /r:CoreLab.MySql.dll /r:MySql.Data.dll test.csusing System;
