创建实例-IDbOperator\IFactoryDbOperator

  1. 创建实例
    
    // MySql, 需要先在项目里引用或加载MySql官方库MySql.Data.dll。
    IDbOperator _dber = new MySqlFactoryOperator()
    {
        ConnectionString = "server=127.0.0.1;database=test;uid=user;pwd=testpassword;Connect Timeout=18000"
    };
    
    // SQLite, 需要先在项目里引用或加载Sqlite官方库System.Data.SQLite.dll。
    IDbOperator _dber = new SQLiteFactoryOperator()
    {
        ConnectionString = "Data Source=.\data\test.db3;"
    };
    
    // Sql Server, 需要先在项目里引用或加载Sql Server官方库System.Data.SqlClient.dll。
    IDbOperator _dber = new MsSqlFactoryOperator()
    {
        ConnectionString = "Server=127.0.0.1;Database=test;Uid = user; Pwd=testpassword;"
    };
    
    
  2. 使用创建全局实例
    
    // MySql
    IDbOperator _dber = Db.Hub.GetDberOrNew<MySqlFactoryOperator>();
    _dber.ConnectionString = "server=127.0.0.1;database=test;uid=user;pwd=testpassword;Connect Timeout=18000";

        @"insert table3 (Values) values (@Value2);",
        @"insert table3 (Values) values (@Value3);",
    } ;
    var _count = _dber.Execute(_sqls, _parameters);//直接执行SQL
