特定的网络接口的IPv4的可用性 - 无连接，本地互联网 [英] Specific network interface IPv4 availability - No connectivity, Local, Internet

问题描述

        NetworkInterface[] nets = NetworkInterface.GetAllNetworkInterfaces();

        foreach (var n in nets)
        {
            // TODO: determine connectivity status of each network interface
            // ( mainly interested in IPv4 connectivity )
        }

• 在这个问题的不是一般的互联网连接，因此使用说<一href="http://stackoverflow.com/questions/6411145/how-to-check-inernet-connectivity-for-pc"><$c$c>GetIsNetworkAvailable()是不是解决
• <一个href="http://msdn.microsoft.com/en-us/library/system.net.networkinformation.networkinterface.operationalstatus.aspx"相对=nofollow> OperationalStatus.Up 可以用来过滤掉一些不活动的网络接口，但不是全部 - OperationalStatus.Up留下一些这显示无网络连接作为IPv4和IPv6
接口
• 我也知道<一个href="http://stackoverflow.com/questions/151231/how-do-i-get-the-local-network-ip-address-of-a-computer-programmatically-c/151349#151349">how获得的IPv4 UnicastAddresses ，那么是什么/是有用的？
• 在我没有找到相关的<一个什么href="http://stackoverflow.com/questions/359596/identifying-active-network-interface-in-net/359640#359640">these WMI
的部分
• This question is not about general internet connectivity and as such using say GetIsNetworkAvailable() is not a solution
• OperationalStatus.Up can be used to filter out some inactive network interfaces, but not all - OperationalStatus.Up leaves in some interfaces that show "No network access" for both IPv4 and IPv6
• I'm also aware how to get the IPv4 UnicastAddresses, but then what / is that useful?
• I could not find anything relevant in these sections of WMI



推荐答案

我觉得你上面显示的对话框微软使用是通过编码对网络位置感知API获得的信息。

I think the Microsoft dialog you show above is using information gained by coding against the Network Location Awareness API.
