是否可以重写代码以减少选择次数？(Is possible to rewrite the code so as to reduce the number of selects?)

是否可以重写代码以减少选择次数？(Is possible to rewrite the code so as to reduce the number of selects?)

但是这段代码测试正确我想知道有些东西是不正确的，因为3嵌套的SELECT（）。 是否可以用2个嵌套的SELECT（）重写代码？

var sums = Enumerable.Range(1, int.Parse(Console.ReadLine())) .Select(x => Console.ReadLine()) .Select(y => y.Split(' ') .Select(int.Parse).Sum());

However this code tested correctly I am wondering about there is something is not correct, because 3 nested SELECT(). Is possible to rewrite the code with 2 nested SELECT()?

var sums = Enumerable.Range(1, int.Parse(Console.ReadLine())) .Select(x => Console.ReadLine()) .Select(y => y.Split(' ') .Select(int.Parse).Sum());

最满意答案

您可以将ReadLine与Split结合使用：

var sums = Enumerable.Range(1, int.Parse(Console.ReadLine())) .Select(x => Console.ReadLine().Split(' ').Select(int.Parse).Sum());

You can combine the ReadLine with the Split:

var sums = Enumerable.Range(1, int.Parse(Console.ReadLine())) .Select(x => Console.ReadLine().Split(' ').Select(int.Parse).Sum());
