推荐答案

您可以使用

You can get the IP address of the client using the HttpRequest.UserHostAddress property (an instance can be accessed using this.Request from any page or using static property HttpContext.Current).

据我所知，没有标准的方法可以将IP地址与指定范围进行比较，因此您需要自己实现这一点.

As far as I know, there is no standard method that would compare the IP address with a specified range, so you'll need to implement this bit yourself.

您可能需要针对每个请求进行检查，可以在每个页面(要阻止的页面)的 OnInit 方法中或在

You'll probably want to check this for every request, which can be done either in the OnInit method of every page (that you want to block) or in the BeginRequest event of the application (typically in Global.asax).

如果检测到被阻止的地址，则可以使用

If you detect a blocked address, you can output an empty (placeholder) page using Server.Transfer method (Response.End would be another alternative, but that simply cuts the page - returning an empty page, while Server.Transfer allows you to output some message to the client).
