如何匿名类型使用LINQ与lambda语法产生的呢？ [英] How can anonymous types be created using LINQ with lambda syntax?

问题描述

我有一个使用lambda语法LINQ查询：

I have a LINQ query that uses lambda syntax:

var query =
    books
        .Where(book => book.Length > 10)
        .OrderBy(book => book.Length)

我想创建一个匿名类型来存储投影，类似于：

I would like to create an anonymous type to store the projection, similar to:

var query = from book in books
            where book.Length > 10
            orderby book
            select new { Book = book.ToUpper() };

如何在lambda语法中选择新的？

How do I "select new" in lambda syntax ?

谢谢，
