EFCore 设置外键

随便搞两个实体类举例:  标红处所展示会生成外键关系

public class Book
{/// <summary>/// id/// </summary>public int Id { get; set; }/// <summary>/// 书本名称/// </summary>public string Name { get; set; }/// <summary>/// 价格/// </summary>public decimal Price { get; set; }/// <summary>/// 所属类型/// </summary>public string Type { get; set; }/// <summary>/// 添加时间/// </summary>public DateTime CreatTime { get; set; }public int PostId { get; set; }
}

public class Post
{/// <summary>/// 借书人/// </summary>public int PostId { get; set; }/// <summary>/// 姓名/// </summary>public string PostName { get; set; }/// <summary>/// 性别/// </summary>public string Sex { get; set; }/// <summary>/// 住址/// </summary>public string Address { get; set; }public List<Book> Books { get; set; } = new();
}
