我有一个加载并生成7个不同随机数的表单,从1到13,1是Ace,13是King.在生成7个不同的随机数后,它将每个随机数放入7个图像框中.我正在使用if语句显示图片框.
它还循环通过一系列“黑桃,心,俱乐部和钻石”,13次.
我的if语句如下：
if (cardNum == 1 && cardType == "Spades")
{
pictureBox1.Image = ace_of_spades;
}
else if (cardNum == 1 && cardType == "Hearts")
{
pictureBox1.Image = ace_of_hearts;
}
else if (...)
{
//change picture Box
} //repeat it like 50 times
是否有一种简单,容易的方法来挑选7张随机卡并在图片框中显示它们？
这是非常耗时的,就像我这样做.
解决方法
如此多的非OOP建议如何处理这个问题.这是我的解决方案,它允许每个对象跟踪自己,并将提供一种简单的方式来洗牌并获得与每张卡相关的图像(我已经写了几张纸牌游戏).
要存储实际图像,请将它们作为资源文件嵌入到项目中,并以特定方式命名：
> card_Club_1
> card_Club_2
> card_Club_3
>等……
然后,当您需要卡片图像时,您只需组合套装和值并从资源管理器请求该资源名称,如下所示.此方法需要更多的设置和规划,但会为您提供更清晰的代码.您甚至可以在一个单独的项目中执行所有这些操作,然后通过在应用程序中引用要提供一副卡片的DLL来重新使用类/资源.
enum Suit : uint
{
Club = 0,Heart,Spade,Diamond
}
class Card
{
public int
Value;
public Suit
Suit;
public System.Drawing.Image GetImage()
{
return System.Drawing.Image.FromStream(
global::cardLibraryProject.Properties.Resources.ResourceManager.GetStream(string.Format("card_{0}_{1}",this.Suit,this.Value))
);
}
}
class Deck
{
System.Collections.ArrayList
_arr;
private Deck()
{
this._arr = new System.Collections.ArrayList(52);
}
void Add(Card crd)
{
if (!this._arr.Contains(crd))
this._arr.Add(crd);
}
public void Shuffle()
{
Random rnd = new Random(DateTime.Now.Millisecond);
System.Collections.ArrayList tmp1 = new System.Collections.ArrayList(this._arr);
System.Collections.ArrayList tmp2 = new System.Collections.ArrayList(52);
while (tmp1.Count > 0)
{
int idx = rnd.Next(tmp1.Count);
tmp2.Add(tmp1[idx]);
tmp1.RemoveAt(idx);
}
this._arr = tmp2;
tmp1.Clear();
tmp2.Clear();
}
public static Deck CreateDeck()
{
Deck newDeck = new Deck();
for (int s = 0; s < 4; s++)
for (int i = 0; i < 13; i++)
newDeck.Add(new Card { Value = i,Suit = (Suit)s });
return newDeck;
}
}
class Program
{
public void Main(string[] args)
{
Deck cards = Deck.CreateDeck();
cards.Shuffle();
pictureBox1.Image = cards[0].GetImage();
// code to play game would go here. ObvIoUsly,if you took
// my suggestion about creating a "Cards" library,then you
// wouldn't have a "void Main" at all,and this would
// all go in the application that was the actual game.
}
