示例1: Main
//引入命名空間
using System;
using System.Net;
using System.Net.Sockets;
class IsLoopbackTest
{
private static void Main(string[] args)
{
if (args.Length == 0)

// No parameters entered. Display program usage.
Console.WriteLine("Please enter an IP address.");
Console.WriteLine("Usage: >ipaddress_isloopback any IPv4 or IPv6 address.");
Console.WriteLine("Example: >ipaddress_isloopback 127.0.0.1");
Console.WriteLine("Example: >ipaddress_isloopback 0:0:0:0:0:0:0:1");
return;
}
else

parse(args[0]);
}
}
// This method calls the IPAddress.Parse method to check if the
// passed ipAddress parameter is in the correct format.
// Then it checks whether it represents a loopback address.
// Finally, it displays the results.
private static void parse(string ipAddress)
{

// or IPv6 loopback address.
