查詢Linq到Sql的排序

Question

我想弄清楚訂購我的sql查詢結果的更好方法。

到目前爲止，我有

List<ArticlePost> articlePosts = new List<ArticlePost>(); 
     IQueryable<ArticlePost> query = from ArticlePost in ArticlePostTable select ArticlePost; 
     foreach (ArticlePost ArticlePost in query) 
      articlePosts.Add(ArticlePost); 
     articlePosts = articlePosts.OrderByDescending(ArticlePost => ArticlePost.atclID).ToList(); 

這是使用LINQ或排序名單的好方法有什麼辦法可以改善嗎？

Answer 1

以下情況出現了什麼問題？

var articlePosts = ArticlePostTable.OrderByDescending(ap => ap.actlId).ToList(); 

Answer 2

var articlePosts = (
    from post in ArticlePostTable 
    orderby post.atclID descending 
    select post) 
    .ToList(); 

Answer 3

試試這個：

List<ArticlePost> articlePosts = 
    ArticlePostTable 
    .OrderByDescending(ArticlePost => ArticlePost.atclID) 
    .ToList();
