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:

//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; } } |

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(); } |
3.运行结果
希望本文所述对大家的C#程序设计有所帮助。
