LinQ中查询方法转为查询表达式

Question

string[] numbers = {"zero","one","two","three","four","five","six","seven","eight","nine"};
var query = numbers.Where((n, index) => n.Length<index) ;

//怎样转成下面的写法(这里n.index是错误的)
//var query = from n in numbers
//            where n.Length < n.index
//            select n;

上面代码中，index表示numbers数组中的元素的序号。

1.转为查询表达式的格式该怎么写？请教各位。

2.LinQ的这两种写法是否都是可以相互转换的？

Answer 1

numbers select转对象后判断

            var query = from n in numbers.Select((n, index) => new { n, index })
                        where n.n.Length < n.index
                        select n.n;

            foreach (var r in query) Console.WriteLine(r);
            Console.ReadKey();
