C# ODBC访问MySQL数据库

废话不说了，直接进入主题，C# ODBC访问MySQL数据库：
1.安装Microsoft ODBC.net：我安装的是mysql-connector-odbc-3.51.22-win32.msi
2.安装MDAC 2.7或者更高版本：我安装的是mdac_typ.exe 2.7简体中文版
3.安装MySQL的ODBC驱动程序：我安装的是 odbc_net.msi
4.管理工具 -> 数据源ODBC –>配置DSN…
5.解决方案管理中添加引用 Microsoft.Data.Odbc.dll(1.0.3300)
6.C# ODBC访问MySQL数据库代码中增加引用 using Microsoft.Data.Odbc;
