Where 生成筛选序列,然后 Orderby 对Where 所生成的序列进行排序。 由于查询返回 IEnumerable,因此可通过将方法调用链接在一起在方法语法中撰写查询。 使用查询语法编写查询时,编译器会执行此组合。 因为查询变量不存储查询的结果,所以可以随时修改它或将它用作新查询的基础(即使在执行它之后)。

In the previous code example, theEnumerable.OrderBymethod is invoked by using the dot operator on the call toWhere.Whereproduces a filtered sequence, and thenOrderbysorts the sequence produced byWhere. Because queries return anIEnumerable, you compose them in method syntax by chaining the method ...
Figure 1 also uses the OrderByDescending operator to order the sequence of projected entities by the calculated total. If two customers had the same total, an additional ordering operator could be used to further define the ordering. For example, the foreach statement in Figure 1 could be ...
