linq - XQuery 催生了 LINQ 吗？

Question

我正在阅读 XQuery(来自此链接:[1])。 LINQ(更准确地说是查询表达式)似乎几乎是它的复制品。所以我想知道 Microsoft 是否真的只是复制了 XQuery 并在其上添加了一些语法糖。我想说的是受到启发，但描述似乎不够有力。

An example:

// LINQ - Query Expression
var winners = from r in racers
   where r.Wins > 3
   orderby r.Wins descending
   select r;

// XQuery
for $racer in doc("racers.xml")/Racers/Racer
  where $racer/Wins > 3
  order by $racer/Wins descending
  return $racer

Answer 1

不，LINQ 不是从 XQuery 复制的。

正如 Eric Lippert 在 this post 中指出的那样:

The design of LINQ query comprehensions was heavily influenced by the design of Haskell. Haskell expert Erik Meijer was on the C# language design committee when we designed LINQ; his insights were very valuable.
