Linq查詢錯誤

Question

public class Employee 
{ 
    [Key] 
    public int EmployeeID { get; set; } 
    public string Name { get; set; } 
    public int DesignationID { get; set; } 

    public virtual Designation Designation { get; set; } 
} 


(from emp in dc.Employee 
    select new Employee { Employee = emp , Designation = emp.Designation }).Single(); 

它給我就行了錯誤"Models.Employee does not contain a definition for Employee"Employee = emp

Answer 1

所以這是簡單的錯誤說，你的模型不包含定義Employee，所以你應該寫這樣的事情：

(from emp in dc.Employee 
    select new Employee { Name = emp.Name ,... 

如果你想有一個員工對象，你可以創建這樣一個視圖模型：

public class EmployeeViewModel 
{ 
    public Employee Employee {get; set;} 
    public Designation Designation {get; set;} 
} 

然後寫您的查詢是這樣的：

select new EmployeeViewModel { Employee = emp , Designation = emp.Designation }).Single();
