WPF page dynamic generation method, system, equipment and medium

Technical Field

The invention relates to the technical field of desktop application program development, in particular to a WPF page dynamic generation method, a WPF page dynamic generation system, WPF page dynamic generation equipment and WPF page dynamic generation media.

Background

WPF (Windows Presentation Foundation) is a Windows-based user interface Framework launched by Microsoft, belongs to a part of NET Framework 3.0, provides a uniform programming model, language and Framework, does the work of separation interface designers and developers, and provides a brand-new multimedia interaction user graphical interface.

In the process of WPF page development, since the functions and requirements of the WPF page can change from moment to moment along with the progress of a project, the completed function modules need to be modified from time to time. In order to reduce the workload increased by the change of functions and requirements, the easily-changed part and the difficultly-changed part of the WPF page need to be combed, and the post-modification work mainly aims at the easily-changed part.

Modification of the easily changeable portion, there are conventionally two methods as follows: the method is characterized in that firstly, the changed part is directly hard-coded and interpreted and modified in the main program, but the defects that the whole project cannot be completely recompiled even if the changed part is slightly modified, verification and backup are carried out after the program is updated and iterated, and the modification is not necessarily suitable for other clients, so that the versions are numerous and difficult to maintain are caused; the second method uses script, which is interpreted and executed during the operation of the project, but the efficiency is much lower than that of the compiled language which is directly compiled into the executable code of the computer, and the defects of insufficient powerful function and slow speed exist.

Therefore, how to provide a method, a system, a device and a medium for dynamically generating a WPF page to achieve improvement of efficiency and flexibility of WPF page generation becomes an urgent problem to be solved.
