不要屬性

Question

我有DB命令，由2個表：

**Job** 
    job_id (int, primary key), 
    job_nm (nchar(50)) 

**Employee** 
    empl_id (int, primary key) 
    job_id (int, forein key) (one-to-many) 
    first_name (nchar(50)) 
    last_name (nchar(50)) 
    salary (float) 

I輸出由頁表（5行逐頁）。 它實現：

ViewBag.Tab = (from employee in db.Employees 
       join job in db.Jobs on employee.job_id equals job.job_id 
       where job.job_nm == sel1 
       orderby employee.salary 
       select employee 
      ).Skip(pageSize * pageNum) 
       .Take(pageSize) 
       .ToList(); 

但我已經通過「工資」 - 場列表未排序。

我試過這段代碼：

ViewBag.Tab = (from employee in db.Employees 
       join job in db.Jobs 
       on employee.job_id equals job.job_id 
       where job.job_nm == sel1 
       orderby employee.salary 
       select employee 
      ).Skip(pageSize * pageNum) 
       .Take(pageSize) 
       .ToList() 
       .OrderBy(s => s.salary); 

，但還沒有結果。

我做錯了什麼？

OrderBy需要在Skip和Take之前。其他方面，你只是要訂購你的小結果集。

嘗試：

ViewBag.Tab = (from employee in db.Employees 
       join job in db.Jobs 
       on employee.job_id equals job.job_id 
       where job.job_nm == sel1 
       orderby employee.salary 
       select employee 
      ).OrderBy(s => s.salary) 
       .Skip(pageSize * pageNum) 
       .Take(pageSize) 
       .ToList();
