c# 计算1-100之间的所有奇数的和

求1-100之间所有奇数整数和：

 class Program
    {
        static void Main(string[] args)
        {
           int sum= GetOdd(1,100);
            Console.WriteLine("1-100之间所有奇数整数和{0}",sum);
            Console.ReadKey();
        }
        /// <summary>
        /// 奇数和
        /// </summary>
        /// <param name="p1"></param>
        /// <param name="p2"></param>
        /// <returns></returns>
        private static int GetOdd(int p1, int p2)
        {
            int sum = 0;
            for (int i = p1; i <= p2; i++)
            {
                if (i%2!=0)
                {
                    sum += i;
                }
            }
            return sum;
        }
    }
