我就是这样做的.
您需要使用System.Net和System.DirectoryServices.
// get root of the directory data tree on a directory server
DirectoryEntry dirEntry = new DirectoryEntry("LDAP://rootDSE");
// get the hostname of the directory server of your root (I'm assuming that's what you want)
string dnsHostname = dirEntry.Properties["dnsHostname"].Value.ToString();
IPAddress[] ipAddresses = Dns.GetHostAddresses(dnsHostname);
