这是不可能的-浏览器是客户端软件.

您的服务器正在运行您的C#代码.服务器如何知道客户端已做某事?它不能订阅客户端事件"，这恰恰是关闭浏览器的目的.

取而代之的是，由您的设计决定浏览器是否通知服务器已发生事件. *您需要在客户端上运行一些代码以通知服务器*

您在这里的选择是有限的. Javascript是显而易见的选择，因为它与跨浏览器兼容，并且您将有很大的几率启用它.

我见过的一种解决方案是让javascript订阅客户端上的"onclosing"事件，并在事件处理程序中调用网络服务以告知服务器我"已关闭浏览器窗口''

It''s impossible - The browser is a client piece of software.

Your server is running your C# code. How is the server ever going to know that the client has done something? It can''t subscribe to ''client events'', which is exactly what closing the browser is.

Instead, it''s up to your design to make the browser inform the server that an event has taken place. *You need to run some code on the client to inform the server*

Your options here are limited. Javascript is the obvious choice, because it''s cross browser compatible and you''ve a fairly high % chance that it''s going to be enabled.

A solution I''ve seen used for this is to have javascript subscribe to the ''onclosing'' event on the client, and call a web service in the event handler to tell the server ''I''ve closed the browser window''
