Program.cs

using System; using System.Collections.Generic; using System.Linq; public class  합계카운트평균 {     public static void Main()     {         int[] data = {3,5,4,2,1};              //Pcrocess         var q = from d in data where d%2 ==0 select d;         int sum = q.Sum(); //합계         int cnt = q.Count(); //카운트         //평균         int avg = Convert.ToInt32(q.Average()); //sum /cnt;             int max = (from d in data select d).Max(); //최대값         int min = (from d in data select d).OrderByDescending                                                (p => p).Last(); //최소값 오더바이         //Output         Console.WriteLine("합계 : {0}                              \n카운트 : {1}                                 \n평균 : {2}",sum,cnt, avg);                 Console.WriteLine("최대값 : {0}",                                   (from d in data select d).Max()); //변수 사용X         Console.WriteLine("최소값 : {0}",min); //변수를 사용     } }
