在Ibatis.net的帮助文档中有介绍多数据库支持，但是没有写全代码，后来查看其源码，并结合帮助文档，找到了解决方法，其实道理就是另行实现一个Mapper.如AnthorMapper： Apache

}
以上代码只是修改了IBatis.net中的Mapper的代码，将_mapper = builder.ConfigureAndWatch (handler);修改为_mapper = builder.ConfigureAndWatch ("AnthorMap.config",handler)，就是根据另一个AnthorMap.config文件来生成SqlMapper。
AnthorMap.config和默认的SqlMap.config一样，只是根据你的数据不同设置不同而已，测试AnthorMap.config如下如下：
xmlns="http://ibatis.apache.org/dataMapper"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<settings>
<setting useStatementNamespaces="true"/>
</settings>
<providers resource="ServerConfig/providers.config"/>
<!-- Database connection information -->
<database>
<provider name="sqlServer2.0"/>
<dataSource name="CrmSystem" connectionString="server=.;database=TestDB;uid=sa;pwd="/>
</database>
<sqlMaps>
<sqlMap embedded="Test.Domain.Weather.xml,Test.Domain" />
</sqlMaps>
</sqlMapConfig>
接下来就可以使用AntherMapper来创建ISqlMapper了。如下：
{
ISqlMapper map = AnthorMapper.Instance();
return map.QueryForList<Weather>("Weather.Select", null);
}
