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();
}
