如下所示：

复制代码 代码如下:

static void Main()

{

int[] array = { 1, 2, 3, 4, 5, 6, 7 };

MoveNumberArrayToEnd(array, 3);

}

static void MoveNumberArrayToEnd<T>(IList<T> arrayList, int num)

{

if (arrayList.Count < = 0 || arrayList.Count < num)

{

throw new RankException();

}

var query = (from number in arrayList

orderby number descending

select number).Take(arrayList.Count - num).Concat(arrayList.Take(num));

query.ToList().ForEach(q => Console.WriteLine("{0}", q));

}
