本文实例讲述了C#实现将数组内元素打乱顺序的方法。分享给大家供大家参考。具体如下：

1.泛型类代码


//泛型类
class Item<T>
{
 T[] item;
 //构造函数
 public Item(T[] obj)
 {
  item = new T[obj.Length];
  for (int i = 0; i < obj.Length; i++)
  {
   item[i] = obj[i];
  }
 }
 public Type ShowType() { return typeof(T); } //返回类型
 public T[] GetItems() { return item; } //返回原数组
 //返回打乱顺序后的数组
 public T[] GetDisruptedItems() 
 {
  //生成一个新数组：用于在之上计算和返回
  T[] temp;
  temp = new T[item.Length];
  for (int i = 0; i < temp.Length; i++) { temp[i] = item[i]; }
  //打乱数组中元素顺序
  Random rand = new Random(DateTime.Now.Millisecond);
  for (int i = 0; i < temp.Length; i++)
  {
   int x, y; T t;
   x = rand.Next(0, temp.Length);
   do
   {
    y = rand.Next(0, temp.Length);
   } while (y == x);
   t = temp[x];
   temp[x] = temp[y];
   temp[y] = t;
  }
  return temp;
 }
}

2.Main函数调用


static void Main(string[] args)
{
 int[] array = new int[] { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
 //输出数组类型
 Item<int> disrupter = new Item<int>(array);
 Console.WriteLine("数组类型：" + disrupter.ShowType().ToString());
 //输出数组
 Console.Write("原输入数组为：");
 for (int i = 0; i < array.Length; i++)
 {
  Console.Write(array[i].ToString() + ' ');
 }
 Console.WriteLine();
 //输出一个打乱后数组
 int[] disruptedArray = disrupter.GetDisruptedItems();
 Console.Write("打乱后数组为：");
 for (int i = 0; i < disruptedArray.Length; i++)
 {
  Console.Write(disruptedArray[i].ToString() + ' ');
 }
 Console.WriteLine();
 Console.ReadLine();
}
