C#迷你猜数实例分析

本文实例讲述了c#迷你猜数。分享给大家供大家参考。具体如下：

using system; 
using system.collections.generic; 
using system.linq; 
using system.text; 
using system.threading.tasks; 
namespace 迷你猜数 
{ 
 class program 
 { 
  static void main(string[] args) 
  { 
   list<int> lisdata = getdata(); 
   lisdata = filterdata(lisdata, 4659, 0, 1); 
   lisdata = filterdata(lisdata, 8763, 0, 1); 
   lisdata = filterdata(lisdata, 1035, 0, 1); 
   lisdata = filterdata(lisdata, 3249, 1, 1); 
   lisdata = filterdata(lisdata, 0497, 0, 2); 
   lisdata = filterdata(lisdata, 9148, 0, 2); 
   foreach(var num in lisdata) 
   { 
    console.writeline(num); 
   } 
   console.readkey(); 
  }

      } 
     } 
    } 
   } 
   return lisdata; 
  } 
  private static list<int> filterdata(list<int> lisdata,int num,int a,int b) 
  { 
   list<int> lisdatanum=new list<int>(); 
   int[] lisnum = new int[4]; 
   //将num拆分成一个数组 
   int[] numnum = splitnum(num);

    int bnum = 0; 
    //将data拆分成一个数组 
    lisnum = splitnum(data); 
    #region 求a，b的个数 
    for (int i=0;i<4;i++) 
    { 
     //求a的个数 
     if(numnum[i]==lisnum[i]) 
     { 
      anum++; 
     } 
     //求b的个数 
     for(int j=0;j<4;j++) 
     {

      { 
       bnum++; 
      } 
     } 
    } 
    bnum -= anum; 
    #endregion 求a,b的个数 
    //判断a,b 
    if((anum==a)&&(bnum==b)) 
    {

    } 
   } 
   return lisdatanum; 
  } 
  /// <summary> 
  /// 拆分四位数

  private static int[] splitnum(int num) 
  { 
   int[] numnu = new int[4]; 
   for (int i = 0; i < 4; i++) 
   { 
    numnu[i] = num % 10; 
    num = num / 10; 
   }
