MVC3：在“仅限代码”中设置默认值

Question

如何为我的“仅限代码”类（传递给sdf或mdf）设置默认值？ MVC3版本是否支持此功能？

Answer 1

您应该可以通过类构造函数设置默认值。例如 - 我有以下数据模型类。我正在使用MVC3和实体框架4.1。

namespace MyProj.Models 
{ 
    using System; 
    using System.Collections.Generic; 

    public partial class Task 
    { 
     public Task() 
     { 
      this.HoursEstimated = 0; 
      this.HoursUsed = 0; 
      this.Status = "To Start"; 
     } 

     public int ID { get; set; } 
     public string Description { get; set; } 
     public int AssignedUserID { get; set; } 
     public int JobID { get; set; } 
     public Nullable<decimal> HoursEstimated { get; set; } 
     public Nullable<decimal> HoursUsed { get; set; } 
     public Nullable<System.DateTime> DateStart { get; set; } 
     public Nullable<System.DateTime> DateDue { get; set; } 
     public string Status { get; set; } 

     public virtual Job Job { get; set; } 
     public virtual User AssignedUser { get; set; } 
    } 
}
