The IPAddress class in the System.Net namespace represents an address in either protocol.
It has a constructor accepting a byte array, and a static Parse method accepting a correctly formatted string:
using System;
using System.Net;
using System.Linq;
using System.Text;
class Program
{
static void Main()
{
IPAddress a1 = new IPAddress(new byte[] { 101, 102, 103, 104 });
IPAddress a2 = IPAddress.Parse("101.102.103.104");
Console.WriteLine(a1.Equals(a2)); // True
Console.WriteLine(a1.AddressFamily); // InterNetwork
IPAddress a3 = IPAddress.Parse("[EEA0:FFFF:EEEA:EEA3:4FF2:54fA:41BC:8D31]");
Console.WriteLine(a3.AddressFamily); // InterNetworkV6
}
}
The output:
True
InterNetwork
InterNetworkV6
An IP address and port combination is represented in the .NET Framework by the IPEndPoint class:
using System;
using System.Net;
using System.Linq;
using System.Text;
class Program
{
static void Main()
{
IPAddress a = IPAddress.Parse("101.102.103.104");
IPEndPoint ep = new IPEndPoint(a, 222); // Port 222
Console.WriteLine(ep.ToString());
}
}
The output:
101.102.103.104:222
