哪位大哥有获取局域网内所有连接路由器的机器ip的代码

如题 --------------------编程问答--------------------

            IPAddress[] ipadd;

            string hostname = Dns.GetHostName();

            ipadd=Dns.GetHostAddresses(hostname);

           

            foreach (IPAddress ip in ipadd)

            {

                MessageBox.Show(hostname);

                MessageBox.Show(ip.ToString());

            }

--------------------编程问答-------------------- 没做过。关注…… --------------------编程问答-------------------- 可以首先获得本机的IP地址，然后把IP最后一位从0枚举到255,并Ping这些机器

但这样的效率较低，一般到多线程其速度才能让人接受，我推荐用net view命令：



 Process p = new Process();

            p.StartInfo.FileName = "net";

            p.StartInfo.Arguments = "view";

            p.StartInfo.CreateNoWindow = true;

            p.StartInfo.UseShellExecute = false;

            p.StartInfo.RedirectStandardOutput = true;

            p.Start();

            while (!p.StandardOutput.EndOfStream)

            {

                string s = p.StandardOutput.ReadLine();

                if (s.StartsWith(@"\\"))

                {

                    try

                    {

                        Console.WriteLine(Dns.GetHostByName(s.Substring(2, s.IndexOf(' ') - 1)).AddressList[0].ToString());

                    }

                    catch { }

                }

            }

效果如下图：

--------------------编程问答--------------------    DirectoryEntry root = new DirectoryEntry("WinNT:");
    DirectoryEntries domains = root.Children;
    domains.SchemaFilter.Add("domain");
    foreach (DirectoryEntry domain in domains) {
  IPHostEntry iphe = null;
    try {
        iphe = Dns.GetHostByName(computer.Name);
      }
    catch { }
  }

或
string strIPAddress="192.168.1.";
            int nStrat = Int32.Parse("1");
            int nEnd =Int32.Parse("255");
            for(int i=nStrat;i<=nEnd;i++)
            {
                string strScanIPAdd = strIPAddress +i.ToString();
                IPAddress myScanIP = IPAddress.Parse(strScanIPAdd);
                try
                {
                    IPHostEntry myScanHost = Dns.GetHostByAddress(myScanIP);
                    string strHostName =myScanHost.HostName.ToString();
                    this.listBox2.Items.Add(strScanIPAdd+"->"+strHostName+"\r");
                }
                catch
                {

                }
            }
