如何將通用列表<匿名類型>轉換爲通用列表<Classname>？

Question

我有一個數據庫，每使用'n'秒插入CPU使用率，我的任務是從數據庫中獲取最新的CPU項目。我想從屬於特定服務器的數據庫中顯示最新的CPU條目，並且我想將結果保存到通用列表中。

什麼我都試過了，

string match = "ServerX" 

    List<UsageCPU> cpus = (from a in db.UsageCPUs 
          where a.ServerID.Contains(match) 
          group a by a.ServerID into b 
          orderby b.Key 
          select new { ServerID = b.Key, 
          Usage = b.FirstOrDefault() }).ToList(); 

，我想通過結果cpus執行進一步的其他步驟循環。

，但我得到以下錯誤

無法隱式轉換類型 'System.Collections.Generic.List < AnonymousType＃1>' 到 「System.Collections.Generic.List < FNC_RAQIT_HM_UI.UsageCPU> 」。

UPDATE 從Satpal下面的查詢工作對我來說..但使用var

var cpus = (from a in db.UsageCPUs 
        where a.ServerID.Contains(match) 
        group a by a.ServerID into b 
        orderby b.Key 
        select new 
        { 
         ServerID = b.Key, 
         Usage = b.FirstOrDefault().Usage 
        }).ToList(); 

     foreach (var item in cpus) 
     { 
      if(bla bla..) 
     } 

好心幫！

Answer 1

使用

List<UsageCPU> cpus = (from a in db.UsageCPUs 
         where a.ServerID.Contains(match) 
         group a by a.ServerID into b 
         orderby b.Key 
         select new UsageCPU //Added UsageCPU 
         { 
          ServerID = b.Key, 
          Usage = b.FirstOrDefault().Usage 
         }).ToList(); 

更新按錯誤

實體不能在LINQ構建以查詢實體

List<UsageCPU> cpus = (from a in db.UsageCPUs 
         where a.ServerID.Contains(match) 
         group a by a.ServerID into b 
         orderby b.Key 
         select new 
         { 
          ServerID = b.Key, 
          Usage = b.FirstOrDefault().Usage 
         }) 
        .AsEnumerable() 
        .Select(x => new UsageCPU 
        { 
         ServerID , 
         Usage    
        }).ToList();

儘量選擇沒有新 當您選擇新的你匿名類型不能通過結果被強制轉換爲UsageCPU型

(from a in db.UsageCPUs 
where a.ServerID.Contains(match) 
group a by a.ServerID into b 
orderby b.Key 
select a) 

，或者使用VAR，然後循環

var cpus = (from a in db.UsageCPUs 
         where a.ServerID.Contains(match) 
         group a by a.ServerID into b 
         orderby b.Key 
         select new { ServerID = b.Key, 
         Usage = b.FirstOrDefault() }).ToList();
