Answer 1

我发现答案myslef它工作Maxlength和minlength是String不是整数.

using System;
using System.Collections.Generic;  
using System.Linq;  
using System.Web;  
using System.ComponentModel.DataAnnotations;  
namespace RestrauntsMVC.Models
{
public class Restraunts
{

    public int id { get; set; }
    [Required]
    public string name { get; set; }
    [Required]
    [Range(1,10,ErrorMessage="Rating must between 1 to 10")]        
    public int rating { get; set; }
    [Required]
    public string location { get; set; }
}
}
