摘　　要：ADO.NET由MicrosoftActiveXDataObjects(ADO)改进而来,可以快速简单地来存取各种数据。只有在应用程序要取得数据或是更新数据的时候才对数据源进行联机的工作,应用程序所要管理的连结减少,负载减轻,效能得到了提升。通过对ADO.NET和ADO多个相应主要对象的比较,并以一个显示可更新数据表的ASP.NET页面程序为例,介绍了ADO.NET的数据访问技术和方法,为完全发挥ADO.NET的优势提供帮助。The improvement of Microsoft ActiveX Data Object (ADO) led to the introduction of ADO.NET, by which various data can be input and output quickly and conveniently. Application program works in combination with the data source only when data were output or changed, without restricting traditional hierarchical application program which remains combined with data source when being operated. Therefore, connections of applied program in management were reduced, with effectiveness improved due to the reduced load. The techniques and methods of ADO.NET data visiting were introduced by means of comparing ADO.NET with multiple corresponding targets of ADO and with illustrating a web page program having renewable data chart. The technique helps to display advantages of ADO.NET.
