如何洗牌清單

使用C＃編寫記憶遊戲。所以我有一張54張圖片的清單。我可以得到另一個列表隨機抓取其中八張圖片。然後我想從第二個列表中添加8個圖像到另一個列表，每個圖像兩次，很簡單。如何洗牌清單

現在我想洗牌的名單，我有點卡住了。我想洗牌的原因是因爲我希望每次遊戲（內存）加載或點擊按鈕（重新啓動）時圖片都是隨機的......下面是我對這個問題的看法：

private void Form2_Load(object sender, EventArgs e) 
{ 
    //generate random number 
    Random r = new Random(); 

    //play music via media player 
    axWindowsMediaPlayer1.uiMode = "none"; 
    axWindowsMediaPlayer1.URL = ("Theme.mp3");    

    //create limage list 
    List<Image> imagesEasy; 
    //populate the 'imageEasy' list 
    imagesEasy = new List<Image>(); 
    imagesEasy.Add(Image.FromFile(@"Baraka01.gif")); 
    imagesEasy.Add(Image.FromFile(@"Baraka02.gif")); 
    imagesEasy.Add(Image.FromFile(@"CyberSubZero01.gif")); 
    imagesEasy.Add(Image.FromFile(@"CyberSubZero02.gif")); 
    imagesEasy.Add(Image.FromFile(@"Cyrax01.gif")); 
    imagesEasy.Add(Image.FromFile(@"Cyrax02.gif")); 
    imagesEasy.Add(Image.FromFile(@"Ermac01.gif")); 
    imagesEasy.Add(Image.FromFile(@"Ermac02.gif")); 
    imagesEasy.Add(Image.FromFile(@"Jade01.gif")); 
    imagesEasy.Add(Image.FromFile(@"Jade02.gif")); 
    imagesEasy.Add(Image.FromFile(@"Jax01.gif")); 
    imagesEasy.Add(Image.FromFile(@"Jax01.gif")); 
    imagesEasy.Add(Image.FromFile(@"JohnnyCage01.gif")); 
    imagesEasy.Add(Image.FromFile(@"JohnnyCage02.gif")); 
    imagesEasy.Add(Image.FromFile(@"Kabal01.gif")); 
    imagesEasy.Add(Image.FromFile(@"Kabal02.gif")); 
    imagesEasy.Add(Image.FromFile(@"Kano01.gif")); 
    imagesEasy.Add(Image.FromFile(@"Kano02.gif")); 
    imagesEasy.Add(Image.FromFile(@"Katana01.gif")); 
    imagesEasy.Add(Image.FromFile(@"Katana02.gif")); 
    imagesEasy.Add(Image.FromFile(@"Kratos01.gif")); 
    imagesEasy.Add(Image.FromFile(@"Kratos02.gif")); 
    imagesEasy.Add(Image.FromFile(@"KungLau01.gif")); 
    imagesEasy.Add(Image.FromFile(@"KungLau02.gif")); 
    imagesEasy.Add(Image.FromFile(@"LiuKang01.gif")); 
    imagesEasy.Add(Image.FromFile(@"LiuKang02.gif")); 
    imagesEasy.Add(Image.FromFile(@"Mileena01.gif")); 
    imagesEasy.Add(Image.FromFile(@"Mileena02.gif")); 
    imagesEasy.Add(Image.FromFile(@"NightWolf01.gif")); 
    imagesEasy.Add(Image.FromFile(@"NightWolf02.gif")); 
    imagesEasy.Add(Image.FromFile(@"NoobSaibot01.gif")); 
    imagesEasy.Add(Image.FromFile(@"NoobSaibot02.gif")); 
    imagesEasy.Add(Image.FromFile(@"QuanChi01.gif")); 
    imagesEasy.Add(Image.FromFile(@"QuanChi01.gif")); 
    imagesEasy.Add(Image.FromFile(@"Raiden01.gif")); 
    imagesEasy.Add(Image.FromFile(@"Raiden02.gif")); 
    imagesEasy.Add(Image.FromFile(@"Scorpian01.gif")); 
    imagesEasy.Add(Image.FromFile(@"Scorpian02.gif")); 
    imagesEasy.Add(Image.FromFile(@"Sektor01.gif")); 
    imagesEasy.Add(Image.FromFile(@"Sektor02.gif")); 
    imagesEasy.Add(Image.FromFile(@"ShangTsung01.gif")); 
    imagesEasy.Add(Image.FromFile(@"ShangTsung02.gif")); 
    imagesEasy.Add(Image.FromFile(@"Sheeva01.gif")); 
    imagesEasy.Add(Image.FromFile(@"Sheeva02.gif")); 
    imagesEasy.Add(Image.FromFile(@"Sindel01.gif")); 
    imagesEasy.Add(Image.FromFile(@"Sindel02.gif")); 
    imagesEasy.Add(Image.FromFile(@"Smoke01.gif")); 
    imagesEasy.Add(Image.FromFile(@"Smoke02.gif")); 
    imagesEasy.Add(Image.FromFile(@"Sonya01.gif")); 
    imagesEasy.Add(Image.FromFile(@"Sonya02.gif")); 
    imagesEasy.Add(Image.FromFile(@"Stryker01.gif")); 
    imagesEasy.Add(Image.FromFile(@"Stryker02.gif")); 
    imagesEasy.Add(Image.FromFile(@"SubZero01.gif")); 
    imagesEasy.Add(Image.FromFile(@"SubZero02.gif")); 

    List<Image> imagesReady; 
    //populate the 'imageReady' list to fill remaining 8 pictureBoxes 
    imagesReady = new List<Image>(); 
    imagesReady.Add(imagesEasy[r.Next(54)]); 
    imagesReady.Add(imagesEasy[r.Next(54)]); 
    imagesReady.Add(imagesEasy[r.Next(54)]); 
    imagesReady.Add(imagesEasy[r.Next(54)]); 
    imagesReady.Add(imagesEasy[r.Next(54)]); 
    imagesReady.Add(imagesEasy[r.Next(54)]); 
    imagesReady.Add(imagesEasy[r.Next(54)]); 
    imagesReady.Add(imagesEasy[r.Next(54)]); 

    List<Image> imagesFinal; 
    //populate the 'imageFinal' list to fill remaining 8 pictureBoxes 
    imagesFinal = new List<Image>(); 
    imagesFinal.Add(imagesReady[0]); 
    imagesFinal.Add(imagesReady[1]); 
    imagesFinal.Add(imagesReady[2]); 
    imagesFinal.Add(imagesReady[3]); 
    imagesFinal.Add(imagesReady[4]);

    imagesFinal.Add(imagesReady[4]); 
    imagesFinal.Add(imagesReady[5]); 
    imagesFinal.Add(imagesReady[6]); 
    imagesFinal.Add(imagesReady[7]); 

    // 
    //need to add or call shuffle method here before assigning pictures to pictureBoxes 
    // 

    //assign pictures to pictureBoxes from the imagesFinal list 
    pictureBox1.Image = imagesFinal[0]; 
    pictureBox2.Image = imagesFinal[1]; 
    pictureBox3.Image = imagesFinal[2]; 
    pictureBox4.Image = imagesFinal[3]; 
    pictureBox5.Image = imagesFinal[4];

我們應該怎麼知道你甚至在談論什麼編程語言？請適當標記。 –

對不起，我忘了添加我正在使用C＃ –

你到目前爲止嘗試過什麼。我的第一個想法是用一個隨機數for循環。 – Tomtom

嘗試實現這個方法：

你可以嘗試這樣的：

List<int> list = new List<int>(); 
Random rnd = new Random(SEED); 
for(int i = 0; i < 15; i++) 
{ 
int nextValue = rnd.Next(MIN,MAX); 
while(list.Contains(nextValue)) 
     nextValue = rnd.Next(MIN,MAX); 
}

這可以很容易地使用LINQ完成與Random。

var rand = new Random(); 
var randomList = imagesEasy.OrderBy (x => rand.Next()).ToList();

這是一個好主意。簡短而甜美。 – Despertar

感謝所有的幫助我結束了使用填充隨機數的數組通過for循環嵌套while循環確保我沒有得到重複。

 int numbA; 
     int[] chosenA = new int[8]; 
     for (int i = 0; i < 8; i++) 
     { 
      numbA = r.Next(9); 

      for (int b = 0; b < 8; b++) 
      { 
       while (chosenA.Contains(numbA) == true) 
       { 
        numbA = r.Next(9); 
        b = 0; 
       } 
      } 
      chosenA[i] = numbA; 
     }

然後使用數組值從列表中調用圖片。

 List<Image> imagesFinal; 
     //populate the 'imageFinal' list to fill remaining 8 pictureBoxes 
     imagesFinal = new List<Image>(); 
     imagesFinal.Add(imagesReady[(chosenA[0] - 1)]); 
     imagesFinal.Add(imagesReady[(chosenA[1] - 1)]); 
     imagesFinal.Add(imagesReady[(chosenA[2] - 1)]); 
     imagesFinal.Add(imagesReady[(chosenA[3] - 1)]); 
     imagesFinal.Add(imagesReady[(chosenA[4] - 1)]); 
     imagesFinal.Add(imagesReady[(chosenA[5] - 1)]); 
     imagesFinal.Add(imagesReady[(chosenA[6] - 1)]); 
     imagesFinal.Add(imagesReady[(chosenA[7] - 1)]); 
     imagesFinal.Add(imagesReady[(chosenA[0] - 1)]); 
     imagesFinal.Add(imagesReady[(chosenA[1] - 1)]); 
     imagesFinal.Add(imagesReady[(chosenA[2] - 1)]); 
     imagesFinal.Add(imagesReady[(chosenA[3] - 1)]); 
     imagesFinal.Add(imagesReady[(chosenA[4] - 1)]); 
     imagesFinal.Add(imagesReady[(chosenA[5] - 1)]); 
     imagesFinal.Add(imagesReady[(chosenA[6] - 1)]); 
     imagesFinal.Add(imagesReady[(chosenA[7] - 1)]);

爲了保證照片置於隨機在pictureboxes我再次使用另一個用於循環用嵌套while循環更高的隨機數生成。

 pictureBox1.Image = imagesFinal[chosenB[0] -1 ]; 
     pictureBox2.Image = imagesFinal[chosenB[1] -1 ]; 
     pictureBox3.Image = imagesFinal[chosenB[2] -1 ]; 
     pictureBox4.Image = imagesFinal[chosenB[3] -1 ]; 
     pictureBox5.Image = imagesFinal[chosenB[4] -1 ]; 
     pictureBox6.Image = imagesFinal[chosenB[5] -1 ]; 
     pictureBox7.Image = imagesFinal[chosenB[6] -1 ]; 
     pictureBox8.Image = imagesFinal[chosenB[7] -1 ]; 
     pictureBox9.Image = imagesFinal[chosenB[8] -1 ]; 
     pictureBox10.Image = imagesFinal[chosenB[9] -1 ]; 
     pictureBox11.Image = imagesFinal[chosenB[10] -1 ]; 
     pictureBox12.Image = imagesFinal[chosenB[11] -1 ]; 
     pictureBox13.Image = imagesFinal[chosenB[12] -1 ]; 
     pictureBox14.Image = imagesFinal[chosenB[13] -1 ]; 
     pictureBox15.Image = imagesFinal[chosenB[14] -1 ]; 
     pictureBox16.Image = imagesFinal[chosenB[15] -1 ];
