1.微软社区上介绍了使用Active Directory 来遍历局域网
利用DirectoryEntry组件来查看网络
网址：http://www.microsoft.com/china/communITy/program/originalarticles/techdoc/DirectoryEntry.mspx- private void EnumComputers()
- {
- using(DirectoryEntry root = new DirectoryEntry("WinNT:"))
- {
- foreach(DirectoryEntry domain in root.Children)
- {
- Console.WriteLine("Domain | WorkGroup: "+domain.Name);
- foreach(DirectoryEntry computer in domain.Children)
- {
- Console.WriteLine("Computer: "+computer.Name);
- }
- }
- }
- }
2、利用Dns.GetHostByAddress和IPHostEntry遍历局域网- private void EnumComputers()
- {
- for (int i = 1; i <= 255; i++)
- {
- string scanIP = "192.168.0." + i.ToString();
- IPAddress myScanIP = IPAddress.Parse(scanIP);
- IPHostEntry myScanHost = null;
- try
- {
- myScanHost = Dns.GetHostByAddress(myScanIP);
- }
- catch
- {
- continue;
- }
- if (myScanHost != null)
- {
- Console.WriteLine(scanIP+"|"+myScanHost.HostName);
- }
- }
- }
3、使用System.Net.NetworkInformation.Ping来遍历局域网- private void EnumComputers()
- {
- try
- {
- for (int i = 1; i <= 255; i++)
- {
- Ping myPing;
- myPing = new Ping();
- myPing.PingCompleted += new PingCompletedEventHandler(_myPing_PingCompleted);
- string pingIP = "192.168.0." + i.ToString();
- myPing.SendAsync(pingIP, 1000, null);
- }
- }
- catch
- {
- }
- }
- PRIVATE void _myPing_PingCompleted(object sender, PingCompletedEventArgs e)
- {
- if (e.Reply.Status == IPStatus.Success)
- {
- Console.WriteLine(e.Reply.Address.ToString() + "|" + Dns.GetHostByAddress(IPAddress.Parse(e.Reply.Address.ToString())).HostName);
- }
- }
