c# 计算1-100之间的所有整数的和

求1-100所有整数和：

 1   class Program
 2     {
 3         static void Main(string[] args)
 4         {
 5            int sum= GetSum(1,100);
 6             Console.WriteLine("1-100之间所有整数和{0}",sum);
 7             Console.ReadKey();
 8         }
 9         /// 

10         /// 1-100之间的所有整数和
11         /// 
12         /// 
13         /// 
14         /// 
15         private static int GetSum(int p1, int p2)
16         {
17             int sum = 0;
18             for (int i = p1; i <= p2; i++)
19             {
20                 sum += i;
21             }
22             return sum;
23 
24         }
25     }
