.Net框架中委托与事件的教学设计与分析

Teaching Design and Analysis of the Delegate and Event under. Net Framework

.Net面向对象程序设计中的委托和事件具有应用广泛的特点,其作为关键性和基础性的知识点,要求学生准确理解并熟练掌握。但由于教学内容中既有新概念的出现,又具有较强的抽象性,给教学带来了一定的难度。采取案例先行、以程序设计解决实际问题的导学方式,可有效地激发学生的学习兴趣,分析委托的本质、委托与事件的关系,明确事件处理流程,有助于学生对知识的理解、掌握和运用,基于以上理念,对教学环节进行较为完整的设计。

. Net object-oriented programming of delegate and event has the characteristics of wide application,as a key and basic knowledge,students are required to accurately understand and grasp skilled. However,due to the emergence of both the new concept of teaching content and its high abstractness,this brings certain difficulty to teaching. This paper adopts the ways of cases and sovling problems through programming design to guide learning,which can effectively stimulate students＇ interest. To analyze the essence of delegate and the relationship between delegate and event and to clear event handling process can help students understand,master and apply knowledge. Based on the above concept,it has carried out the comparatively complete design to teaching.
