推荐答案
如果你只是想检查网络是否正常,那么使用:
If you just want to check if the network is up then use:
bool networkUp
= System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable();
要检查特定接口的状态(或其他信息),请使用:
To check a specific interface's status (or other info) use:
NetworkInterface[] networkCards
= System.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces();
要检查远程计算机的状态,您必须连接到该计算机(请参阅其他答案)
To check the status of a remote computer then you'll have to connect to that computer (see other answers)
