C# IP地址与整数互转的实例代码

发布时间:2019-12-30编辑:脚本学堂
本文分享一例c#实现IP地址与整数互转的代码,挺不错的小例子,有需要的朋友参考下,希望对大家有所帮助。

本节主要内容:
C#实现IP地址和整数的相互转换。

代码:
 

复制代码 代码示例:

//IP地址转整数 整数转IP地址
[StructLayout(LayoutKind.Explicit)]
 public struct IP
 {
     public IP(UInt32 value)
     {
         this._text1 = 0;
         this._text2 = 0;
         this._text3 = 0;
         this._text4 = 0;
         this._value = value;
     }
     public IP(Byte text1, Byte text2, Byte text3, Byte text4)
     {
         this._value = 0;
         this._text1 = text1;
         this._text2 = text2;
         this._text3 = text3;
         this._text4 = text4;
     }
     [FieldOffset(0)]
     private UInt32 _value;
     [FieldOffset(0)]
     private Byte _text1;
     [FieldOffset(1)]
     private Byte _text2;
     [FieldOffset(2)]
     private Byte _text3;
     [FieldOffset(3)]
     private Byte _text4;

     public UInt32 Value
     {
         get { return this._value; }
         set { this._value = value; }
     }
     public Byte Text1
     {
         get { return this._text1; }
         set { this._text1 = value; }
     }
     public Byte Text2
     {
         get { return this._text2; }
         set { this._text2 = value; }
     }
     public Byte Text3
     {
         get { return this._text3; }
         set { this._text3 = value; }
     }
     public Byte Text4
     {
         get { return this._text4; }
         set { this._text4 = value; }
     }

     public override string ToString()
     { //www.jb200.com
         return String.Format("{0}.{1}.{2}.{3}", this._text1.ToString(), this._text2.ToString(),
             this._text3.ToString(), this._text4.ToString());
     }

     public static implicit operator IP(UInt32 value)
     {
         return new IP(value);
     }
     public static explicit operator UInt32(IP ip)
     {
         return ip._value;
     }
 }

测试代码:
 

复制代码 代码示例:

class Program
 {
     static void Main(string[] args)
     {
         IP ip = new IP(192,168,1,1);
         Console.WriteLine(ip);
         UInt32 value = (UInt32)ip;
         Console.WriteLine(value);
         Console.WriteLine(ip.Value);
         IP ip2 = (IP)(1234567);
         Console.WriteLine(ip2);

         Console.ReadKey();
     }
 }
