如何使用LINQ和lambda语法创建匿名类型？

我有一个使用lambda语法的LINQ查询：

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：

 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”？

谢谢，

像这样：

 var query = books .Where(book => book.Length > 10) .OrderBy(book => book.Length) .Select(book => new { Book = book.ToUpper() });
