C#LINQ表达式问题 [英] C# LINQ expression question

问题描述

我有以下示例代码:

string[] digits = { "zero", "one", "two", "three", 
  "four", "five", "six", "seven", "eight", "nine" };

var shortDigits = digits.Where((digit, index) => digit.Length < index);

Console.WriteLine("Short digits:");
foreach (var d in shortDigits)
{
    Console.WriteLine("The word {0} is shorter than its value.", d);
}

是否有一种使用LINQ表达式仅生成 相同输出的方法?

Is there a way generating same output only by using LINQ expressions?

推荐答案

我了解您仅指的是var shortDigits = digits.Where((digit, index) => digit.Length < index);我必须认真思考为什么要创建这样的怪物，如果您指的是生成仅LINQ

I understand you are referring only to var shortDigits = digits.Where((digit, index) => digit.Length < index); I would have to think hard why you'd want to create such a monster if you are referring to generating the whole output with only LINQ

您可以执行以下操作以获得相同的输出:

You could do the following to get the same output:

int i = 0;
var shortDigits = from d in digits
                  where d.Length < i++
                  select d;
