c# - Get local IP address -


in internet there several places show how ip address. , lot of them example:

string strhostname = string.empty; // getting ip address of local machine... // first host name of local machine. strhostname = dns.gethostname(); console.writeline("local machine's host name: " + strhostname); // using host name, ip address list.. iphostentry ipentry = dns.gethostentry(strhostname); ipaddress[] addr = ipentry.addresslist;  (int = 0; < addr.length; i++) {     console.writeline("ip address {0}: {1} ", i, addr[i].tostring()); } console.readline();

with example several ip addresses, i'm interested in getting 1 router assigns computer running program: ip give if wishes access shared folder in computer instance.

if not connected network , connected internet directly via modem no router error. how can see if computer connected network c# , if lan ip address.

to local ip address:

public static string getlocalipaddress() {     var host = dns.gethostentry(dns.gethostname());     foreach (var ip in host.addresslist)     {         if (ip.addressfamily == addressfamily.internetwork)         {             return ip.tostring();         }     }     throw new exception("local ip address not found!"); }

to check if you're connected or not:

system.net.networkinformation.networkinterface.getisnetworkavailable();
