我無法將數據植入我的Webapp中，也不知道出了什么問題。該應用程序運行良好，用戶可以將數據添加到數據庫中。我添加了saveChanges方法，但沒有結果。我認為我正在向數據庫發送空數據，但是我找不到問題。我的文件：DbContext public class BookDbContext: DbContext{    public BookDbContext(DbContextOptions options): base(options)    {    }    public DbSet<Books> Books { get; set; }}種子書public static void Initialize(BookDbContext context)    {        context.Database.EnsureCreated();        if (context.Books.Any())        {            return;        }        var books = new Books[]         {        new Books{Id=1, Title ="Kont of Mount Cristos", Description="About eghteen century", Author="Don Mon", Category=Category.aksion},        new Books{Id=2, Title="Introduction in C Sharp", Description="Learning computer programing", Author="Scott Allen", Category= Category.education},        new Books{Id=3, Title="The Castle", Description="Learning about history", Author="Ismail Kadare", Category= Category.drama},        new Books{Id=4, Title="Madam Bavary", Description="Love story", Author="Gi de Mopasan", Category= Category.romance}         };        foreach (Books b in books)        {            context.Books.Add(b);        }            context.SaveChanges();    }書籍檔案public enum Category{    aksion, drama, romance, education}public class Books{    public int Id { get; set; }    [Required]    public string Title { get; set; }    [Required]    [Display(Name = "Autor Name")]    public string Author { get; set; }    [Required]    [MaxLength(80)]    public string Description { get; set; }    [Required]    public Category Category { get; set; }}
