26 testNum = listNum.Aggregate ( ( m, n ) => m + n );
27 int testNumAdd = listNum.Aggregate ( 0, ( total, next ) => next % 2 == 0 ? total + 1 : total );
28 int testNumAddOpreation = listNum.Aggregate ( 0, ( total, next ) => next % 2 == 0 ? total + 1 : total, fruit => fruit + 100 );
29 }
testNum = listNum.Aggregate ( ( m, n ) => m + n );指定的两列做指定的操作
int testNumAdd = listNum.Aggregate ( 0, ( total, next ) => next % 2 == 0 ? total + 1 : total );在给定的参数上来判断列表的每一个值，然后进行相应的操作。
int testNumAddOpreation = listNum.Aggregate ( 0, ( total, next ) => next % 2 == 0 ? total + 1 : total, fruit => fruit + 100 );在上一个方法的基础上，再传一个委托来实现结果的过滤。
