结合使用UIHint和LINQ to SQL生成的类

using System.ComponentModel.DataAnnotations;

namespace Project.Models
{
  [MetadataType(typeof(ProductsMeta))]
  public partial class Products
  {
    // You can extend the products class here if desired.

    public class ProductsMeta
    {
      // This is a Linq-to-Sql Buddy Class      
      // In here you can add DataAnnotations to the auto-generated partial class

      [Key]
      public int ProductKey { get; set; }

      [Display (Name = \"Product Name\")]
      [Required(ErrorMessage = \"Product Name Required\")]
      [StringLength(255, ErrorMessage = \"Must be under 255 characters\")]
      public string ProductName { get; set; }

      [UIHint(\"MultilineText\")]
      public string Description { get; set; }
    }
  }
}
