C# implements the client pop-up message box encapsulation class instance

This article describes the implementation of C# client pop-up message box encapsulation class. Share it for your reference. The details are as follows:

Running on the server side, a dialog box cannot be popped up on the server side, but C# can achieve the effect of popping up a message box by outputting JS code on the page. This C# class encapsulates the commonly used message box popping up a JS code, which can be called on the server side and displays the dialog box on the client side. Not only can it display the JS warning box, it can also display the mode window, which is very convenient.
