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(,);
             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 = ;
             for (int i = p1; i <= p2; i++)
             {
                 if (i%!=)
                 {
                     sum += i;
                 }
             }
             return sum;
         }
