C# 获取本地IP地址以及MAC地址 
1、通过主机名获取局域网IP地址；
            try
            {
                IPHostEntry ipHostEntry = Dns.GetHostEntry(txtHost.Text);//传递计算机名
if (ipHostEntry.Aliases.Length >0)
                {
                    foreach (string alias in ipHostEntry.Aliases)
                        txtIP.Text = alias;
                }
                //获取IP地址
foreach (IPAddress addr in ipHostEntry.AddressList)
                    txtIPAddress.Text = addr.ToString();//获取IP地址
             }
            catch
            {
                MessageBox.Show("错误的主机名。");
            }
2、通过局域网IP地址获取主机名；
try
            {
               IPHostEntry ipHostEntry = Dns.GetHostByAddress(txtIP.Text); ;//传递IP地址
               txtHostName.Text = ipHostEntry.HostName.ToString()//取得主机名
            }
            catch
            {
               MessageBox.Show("错误的IP地址。");
            }
3、通过局域网IP地址获取Mac地址
publicstaticstring ReadMac(string ip)//传递IP地址,即可返回MAC地址
        {
            string mac ="";
            System.Diagnostics.Process p =new System.Diagnostics.Process();
            p.StartInfo.FileName ="nbtstat";
            p.StartInfo.Arguments ="-a "+ ip;
            p.StartInfo.UseShellExecute =false;
            p.StartInfo.CreateNoWindow =true;
            p.StartInfo.RedirectStandardOutput =true;             
            p.Start(); 
            string output = p.StandardOutput.ReadToEnd();
            int len = output.IndexOf("MAC Address = ");
            if(len>0)
            {
                 mac = output.Substring(len +14, 17);
            }             
            p.WaitForExit();             
            return mac;
        }
