使用C#編寫查詢IP段功能的程序

本文將通過一個(gè)實(shí)例來向大家講解如何使用C#來編寫一個(gè)具備查詢IP段功能的小程序。
    主要功能：查詢一個(gè)IP所有的IP段.
    關(guān)鍵:從Byte數(shù)組到ulong的轉(zhuǎn)換出來的數(shù)字和 IPAddress.Address 返回值的是不一樣的.
    以下是引用片段：
    using System;
    using System.Collections.Generic;
    using System.Text;
    using System.Net;
    namespace IPUtility
    {
    class Program
    {
    static void Main(string[] args)
    {
    IPRangeManage irm = new IPRangeManage();
    irm.Add(new IPRange("石家莊", "219.148.24.0", "219.148.63.255"));
    irm.Add(new IPRange("石家莊", "222.222.0.0", "222.222.63.255"));
    irm.Add(new IPRange("唐山", "219.148.64.0", "219.148.79.255"));
    irm.Add(new IPRange("保定", "219.148.20.0", "219.148.23.255"));
    Console.WriteLine(irm.Search("219.148.56.3").Name);
    Console.ReadLine();
    }
    }
    public class IPRange
    {
    private string _Name = string.Empty;
    private ulong _BeginIP = 0;
    private ulong _EndIP = Int32.MaxValue;
    /**////
    /// IP段名稱
    ///
    public string Name
    {
    get { return _Name; }
    set { _Name = value; }
    }
    /**////
    /// ?始IP
    ///
    public ulong BeginIP
    {
    get { return _BeginIP; }
    set { _BeginIP = value; }
    }
    /**////
    /// ?束IP
    ///
    public ulong EndIP
    {
    get { return _EndIP; }
    set { _EndIP = value; }
    }
    /**////
    /// 此IP段的范?
    ///
    public ulong Range
    {
    get
    {
    return EndIP - BeginIP;
