A data reader object fetches the data from the data source and passes it through directly to your application 数据读取器对象从数据源获取数据,并将这些数据直接传递给应用程序。
In addition to adapters , managed providers include connection objects , data reader objects , and command objects (除适配器以外,托管提供程序还包括连接对象、数据读取器对象和命令对象。
If you use a data reader to read directly from the database , you avoid the extra steps required to manage the dataset 如果您使用数据读取器直接从数据库读取,则可以避免管理数据集所需的额外步骤。
In general , you do not need to work directly with the objects that are used to manage data access , such as datasets or data readers 通常,不需要直接处理用于管理数据访问的对象,如数据集或数据读取器。
Construct , it is simpler to use the looping construct directly in order to iterate through the rows in the data reader 构造的语言中使用此方法检索显式构造函数,但直接使用循环构造来循环访问数据读取器的行却更加简单。
