out关键字

out 关键字 获取数组中最大值及索引

using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace ConsoleApplication1{    class Program    {        static int MaxIndex(int[] m_array,out int m_index)        {            m_index = 0;            int m_Max = m_array[0];            for (int i = 0; i < m_array.Length; i++)            {                if (m_array[i] > m_Max)                {                    m_Max = m_array[i];                    m_index = i;                }            }            return m_Max;        }        static void Main(string[] args)        {            int[] array = new int[5]{5,9,32,25,16};            int maxIndex;            Console.WriteLine("数组中最大的值是：{0}",MaxIndex(array,out maxIndex));            Console.WriteLine("数组中最大值是第{0}号元素：",maxIndex+1);            Console.ReadLine();        }    }}
