c# - 如何将此 SQL Order By 语句转换为 LINQ-To-Object？

Question

这是 SQL ORDER BY :

order by case when [order] is null then 1 else 0 end, [order]

在LINQ-To-Object语句中怎么写？

Answer 1

方法语法

var query = enumerable.OrderBy(x => x.order == null ? 1 : 0).ThenBy(x => x.order);

查询语法

var query = from x in enumerable
            orderby (x.order == null ? 1 : 0), x.order
            select x;
