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 C>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;
