It can help the personnel to implement the task of office automation. The system of office automation prises the OA anization, the OA personnel, the OA equipments, the work environment and the OA information. The office automation has already developed to be a new arisen course, it involves the puter and munication technique, management and behavioral science, system engineering and personmachine engineering etc. it is nowadays very active in the application fields of puter. The purpose of office automation is to apply electronic information technique, offer the advanced OA information means, enhance the efficiency and the quantity of OA management, improve the OA environment, and advance the level of OA science. .NET is a gross that the Microsoft pany release the technique and the product. .NET framework is a new calculation terrace, it simplifies the development of program on the each aspect in the distribute environment of the Inter. is the main technique that could develop in the construction of B/S .It is a new means for creating the dynamic web applying procedure. It provides the larger agilities and more functions to development personnel. This thesis not only introduces the design, development and realization of OA in general under the .NET technique, but also expatiates the .NET framework and the application of the binary tree in the process definition. The first part introduces the purpose of studying OA and the background of developing the OA system。 the fifth part introduces realization of the OA system, and the problem of the OA system and how to solve the problem at last. The OA system is realized by Visual under the Microsoft Windows2020 Server.
