关键注释不起作用
Key annotation not working
我收到以下错误:
Error 1 The type or namespace name 'keyAttribute' could not be found
(are you missing a using directive or an assembly reference?)
enter code here
c:\users\hp\documents\visual studio
2013\Projects\ProductApps\ProductApps\Models\Product.cs 13 10 ProductApps
我的代码:
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Web;
namespace ProductApps.Models
{
public class Product
{
[key]
public int Id { get; set; }
public string ProductName { get; set; }
public string Price { get; set; }
public string Description { get; set; }
}
}
有谁能告诉我为什么会出现错误以及如何解决它?
请加
using System.ComponentModel.DataAnnotations;
你的 using 语句并尝试(大写 K)
[Key]
public int Id { get; set; }
您的项目中是否引用了 System.ComponentModel.Annotations.dll
程序集?
