如何在LINQ中按多个字段排序？

Question

我怎样才能进行多种排序

 return (from p in _db.Pages where p.int_PostStatusId == 2 select p).OrderByDescending(m => m.int_SortOrder);

我想通过int_PageId做订单吗？首先是int_SortOrder然后是int_PageId

Answer 1

二者必选其一ThenBy或ThenByDescending命令的结果OrderBy或OrderByDescending:

return (...)
    .OrderByDescending(m => m.int_SortOrder)
    .ThenBy(m => m.int_PageId);

或者使用查询语法:

orderby p.int_SortOrder descending, p.int_PageId
