我有一个采用传统 3 层设计的 Web 应用程序 (ASP.Net 3.5).如果用户单击一个按钮,则会发生回发,一些中间层和数据层代码会运行,并且屏幕会刷新.如果用户在第一次回发完成之前多次单击该按钮,我的逻辑会变得混乱,并且应用程序可能最终处于无效状态.预防这种情况的最佳方法是什么?
I have a web application (ASP.Net 3.5) with a conventional 3 layer design. If the user clicks a button a postback happens, some middle and data layer code runs, and the screen is refreshed.
