Abstract: With the constant development of information technology today,computer science and technology matures, and provides convenience and needs a lot of people, it has played a more and more important role in every field of human society. Network question answering system is a WEB based application,and with the Internet as the media to realize the remote education. System mainly describes the basic process development, design and development in the use of ASP.NET technology and C# language, SQL and other related technologies,based on object oriented principle, the three layer system structure based on B/W/S. To IIS for the server, SQL Server 2008 as the database platform, provide a platform for the exchange of teachers and students, to explore each other in cyberspace, so that students can acquire knowledge in time and more active.The system includes the immediate answering, file sharing, question and answer questions management, management and maintenance of the background database information module.
Keywords: ASP.NET; online Q & A; B/W/S structure; SQL server
