我如何检查，我有一个开放的网络连接，并可以与在C＃中特定的IP地址？我看到的例子在VB.Net，但他们都用我的结构。 谢谢你。

How do I check that I have an open network connection and can contact a specific ip address in c#? I have seen example in VB.Net but they all use the 'My' structure. Thank you.

推荐答案

如果你只是想检查网络是否正常运行：

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（或其他方式）使用方法：

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，那么你就必须连接到计算机（见其他答案）

To check the status of a remote computer then you'll have to connect to that computer (see other answers)
