摘　　要：在分析主要开发技术的基础上,介绍了如何在.NET平台下用C#语言开发一个实用的通用查询组件,详细叙述了该查询组件的设计方法、功能实现的部分程序代码。在实际数据库的应用系统中,各子系统在调用该组件时只要设置相应的连接字符串参数,就可满足子系统的查询需求,达到通用的要求。在包含多个查询子系统的应用中,通过调用查询组件可以加快开发进度,降低成本,提高软件的开发效率。On the basis of analysis of main development technology, on how to develop a practical general query component by using C# based on .net is introduced, and the design methods, partial program codes about function realization are stated in detail. In an actual database application system, it can satisfy query requirements of all subsystems by seting relevant connection character string when these subsystems call this component, so it meet general demands. In an application system including several query subsystems, it can speed development schedule, reduce cost and improve software development efficiency by calling this component.
