            IPHostEntry ipE = Dns.GetHostByName(sHostName);
            IPAddress[] IpA = ipE.AddressList;
            for (int i = 0; i < IpA.Length; i++)
            {
                Console.WriteLine("IP Address {0}: {1} ", i, IpA[i].ToString());
                string IPAddress= IpA[i].ToString();//ip;// IPAddress;// strIPAddress;

That code will get you the IP address of the server.

You can access the user's IP address with this property: Request.UserHostAddress

回答2:

Get users IP address

Request.ServerVariables("REMOTE_ADDR")
or
Request.UserHostAddress

To get the IP address of the machine and not the proxy use the following code

Request.ServerVariables["HTTP_X_FORWARDED_FOR"];

The code you have used only work in case of windows application (Client server architecture) But to get the users ip address in web application you need to use

Request.UserHostAddress

No matter how hard you try you can only get server IP using server side code in Asp.Net.However the method told in this article will let you access client ip using javascript.refer this https://www.c-sharpcorner.com/blogs/getting-client-ip-address-or-local-ip-address-in-javascript
