1。擷取區域網路ip
IPAddress ipAddr = Dns.Resolve(Dns.GetHostName()).AddressList[0];//獲得當前IP地址
string ip=ipAddr.ToString() ;
2。擷取公網ip
private static string GetIP(){ string tempip = ""; try { WebRequest wr = WebRequest.Create("http://www.ip138.com/ips138.asp"); Stream s = wr.GetResponse().GetResponseStream(); StreamReader sr = new StreamReader(s, Encoding.Default); string all = sr.ReadToEnd(); //讀取網站的資料 int start = all.IndexOf("您的IP地址是:[") + 9; int end = all.IndexOf("]", start); tempip = all.Substring(start, end - start); sr.Close(); s.Close(); } catch { } return tempip;}
3.如果是ADSL上網,擷取公網ip
string tempIP =string.Empty;
if (System.Net.Dns.GetHostEntry(System.Net.Dns.GetHostName()).AddressList.Length >1)
tempIP = System.Net.Dns.GetHostEntry(System.Net.Dns.GetHostName()).AddressList[1].ToString();
