1.把分拣奇数偶数的程序用泛型实现。（List<int>）
2.将int数组中的奇数放到一个新的int数组中返回。
int[] numbers={2,7,9,4,3,8,1,6}
List<int> listOdd=new List<int>();

for(int i=0;i<numbers.length;i++)
{
if (numbers[i]%2!=0)
listOdd.Add(numbers[i]);

}
int[] numOdd=listOdd.ToArray();

3.从整数的List<int>中找最大值，不适用Max方法。

List<int> list=new List<int>(1,2,3,4,5,6,7,8,9);

//Random radom=new Random();
//radom.next()

//list.Add

int temp=0

for(int i=0;i<list.Count;i++)
{
if(list[i]>temp)
{

temp=list[i];
}

}
console.writeline("max is :"+temp);

4.计算字符串中每种字符出现的次数。（面试题）“welcome to china! this is a beautiful county, i think you will like it.here is The great wall”提示：Dictionary<char,int>

5.把1,2,3转换为壹贰叁
string str="1壹 2贰 3叁 4肆 5伍 6陆 7柒 8捌 9玖 0零";

6.简体繁体字转换。

7.编写函数进行日期转换；键输入的大写的日期转换成阿拉伯数字的形式。
二零一二年三月十三日     2012-3-13
二零一二年三月十日       2012-3-10
二零一二年三月二十三日   2012-3-23

            for (int i = 0; i < nums.Length; i++)
            {
                if (Convert.ToInt32(nums[i]) % 2 != 0)
                {
                    listOdd.Add(Convert.ToInt32( nums[i]));
                }
                else
                {
                    listEven.Add(Convert.ToInt32(nums[i]));
                }
            }
            listOdd.AddRange(listEven);
            StringBuilder sb = new StringBuilder();
            for (int i = 0; i < listOdd.Count; i++)
            {
                sb.Append(listOdd[i] + " ");
            }

List<int> listOdd=new List<int>();

for(int i=0;i<numbers.Length;i++)

{

if(numbers[i]%2!=0)

                 listOdd.Add(numbers[i]);

            }

int[] numOdd = listOdd.ToArray();

            foreach (int tenp in numOdd)
            {
                Console.WriteLine(tenp);
            }

            Console.ReadKey();
        }
    }
}

3.从整数的List<int>中找最大值，不适用Max方法。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace 从整数中找最大
{
    class Program
    {
        static void Main(string[] args)
        {
            List<int> list = new List<int>() { 1, 2, 3, 4, 5, 6, 7, 8, 9 };

int temp = 0;

            for (int i = 0; i < list.Count; i++)
            {
                if (list[i] > temp)
                {
                    temp = list[i];
                }
            }
            Console.WriteLine("max is:" + temp);
