一、DTO

避免直接暴露数据库实体

1.1 创建Restaurant的Dto

1. 在Restaurants.Application创建Dtos文件夹；
2. 创建RestaurantDto.cs，FromRestaurant静态方法，只是为了包装真正的实体类只返回需要的属性；

using Restaurants.Domain.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace Restaurants.Application.Dtos
{public class RestaurantDto{public int Id { get; set; }public string Name { get; set; } = default!;public string Description { get; set; } = default!;public string Category { get; set; } = default!;public bool HasDelivery { get; set; }public string? City { get; set; }public string? Street { get; set; }public string? ZipCode { get; set; }public List<DishDto> Dishes { get; set; } = new List<DishDto>();public static RestaurantDto FromRestaurant(Restaurant restaurant){return new RestaurantDto(){Id = restaurant.Id,Name = restaurant.Name,Description = restaurant.Description,Category = restaurant.Category,HasDelivery = restaurant.HasDelivery,City = restaurant.Address?.City,Street = restaurant.Address?.Street,ZipCode = restaurant.Address?.ZipCode,};}}
}

1.2 修改之前未使用Dto的接口
