软件介绍

1、.net 数据库访问通信接口封装，支持 ORM 和 ado.net 方式;ado.net(包含)支持 SQL server，DB2，Oracle，MySQL，Postgresql,access 等;

2、支持.net Core 2.0

2、支持数据库表双向同步

            ////ado.net 使用例子
            string connectionString = string.Empty;
            AdoProvider dbProvider = AdoProvider.CreateProvider(connectionString,ProviderType.SqlServer);
            var adort = dbProvider.Query(new DbExecuteParameter()

                //使用mapper修改对象
                EntityMapper.MapTo(ud, item);
