1             int[] numbers = { 1, 2, 3, 4 };
2             string[] words = { "one", "two", "three" };

4             var numbersAndWords = numbers.Zip(words, (first, second) => first + " " + second);
5 
6             foreach (var item in numbersAndWords)
7                 Console.WriteLine(item);

以数列内容少的为主要参考
