推荐答案

您可以使用 Dns.GetHostEntry 为尝试来解析名称，因为<强>不是每个IP有一个名字

You can use Dns.GetHostEntry to try to resolve the name, because not every IP has a name.

using System.Net;
...

public string GetHostName(string ipAddress)
{
    try
    {
        IPHostEntry entry = Dns.GetHostEntry(ipAddress);
        if (entry != null)
        {
           return entry.HostName;
        }
    }
    catch (SocketException ex)
    {
       //unknown host or
       //not every IP has a name
       //log exception (manage it)
    }

    return null;
}
