也同样ConditionalOrderBy和ConditionalOrderByDescending是有益的。
Using the LINQ DynamicQuery library I could re-write the above query expression instead like so: Notice how the conditional-where clause and sort-orderby clause now take string expressions instead of code expressions. Because they are late-bound strings I can dynamically construct them. For exampl...

In the previous example, thewhereclause filters out all null elements in the categories sequence. This technique is independent of the null check in the join clause. The conditional expression with null in this example works becauseProducts.CategoryIDis of typeint?, which is shorthand forNullable...
