asp.net 点滴事项

1、要进行跳转链接 

      @Html.ActionLink("Edit", "Edit", new { id=item.ID }) 

       return RedirectToAction("Index");

 2、可通过以下方式进行数据实体的验证

       if (ModelState.IsValid)  

 3、如何给默认值

     public ActionResult ssss(int id=0)

 4、以下代码实现的是在clr中进行mapping的时候，找delete就找到deleteconfirmed     

[HttpPost, ActionName("Delete")] 

public ActionResult DeleteConfirmed(int id =0)

 5、验证实例如下

       [Required(ErrorMessage = "Title is required")]

    public string Title { get; set; }

    [Required(ErrorMessage = "Date is required")]
    public DateTime ReleaseDate { get; set; }

    [Required(ErrorMessage = "Genre must be specified")]
    public string Genre { get; set; }

    [Required(ErrorMessage = "Price Required")]
    [Range(1, 100, ErrorMessage = "Price must be between $1 and $100")]
    public decimal Price { get; set; }

    [StringLength(5)]
    public string Rating { get; set; }} 

 

 

 [DataType(DataType.Date)] 
        public DateTime ReleaseDate { get; set; }
       
        [DataType(DataType.Currency)]  public decimal Price { get; set; } 

      [DisplayFormat(DataFormatString = "{0:d}")]

       public DateTime ReleaseDate { get; set; }

ASP.NET MVC Tip #46 — Don't use Delete Links because they create Security Holes.
