[C#基礎]-字串比對，模擬網路遮罩判斷

本篇要分享字串比對，模擬網路遮罩判斷，有興趣的同好，歡迎來一下哈哈 ^ ^。

程式碼

using System; using System.Collections.Generic; using System.Linq; using System.Text;   namespace CS_char_Compare {     class Program     {         //字串比對，模擬網路遮罩判斷         publicbool charCompare(string s, string d)         {             byte[] byte_s = System.Text.Encoding.Default.GetBytes(s);//string -> byte             byte[] byte_d = System.Text.Encoding.Default.GetBytes(d);//string -> byte             int i = 0;             int x=0;             int y=0;             for (i = 0; i < d.Length; i++)             {                 x = byte_s[i];//byte -> int                 y = byte_d[i];//byte -> int                 if (byte_d[i]!='x')//未定義不用判斷                 {                     if (x != y)                     {                         returnfalse;//只要一個不同，就回傳FALSE                     }                 }             }             returntrue;//全部相同         }         staticvoid Main(string[] args)         {             Program p=new Program();               string s="0011001100110011";//資料             string d="xxxxxxxx00110011";//判斷，x代表未定義             bool blncheck;             blncheck = p.charCompare(s, d);             Console.WriteLine(s);             Console.WriteLine(d);             if (blncheck)             {                 Console.WriteLine("true");             }             else             {                 Console.WriteLine("false");             }             string s1= "0011001100110011";//資料             string d1= "xxxxxx1100111011";//判斷，x代表未定義             blncheck = p.charCompare(s1, d1);             Console.WriteLine(s1);             Console.WriteLine(d1);             if (blncheck)             {                 Console.WriteLine("true");             }             else             {                 Console.WriteLine("false");             }             string s2 = "0011001100110011";//資料             string d2 = "xxxxxx1100110011";//判斷，x代表未定義             blncheck = p.charCompare(s2, d2);             Console.WriteLine(s2);             Console.WriteLine(d2);             if (blncheck)             {                 Console.WriteLine("true");             }             else             {                 Console.WriteLine("false");             }             Console.Read();         }     } }
