如何停止EF 7將實體屬性映射到列？

只是為了增加Ricky和bricelam的答案，

有兩種方法可以忽略屬性：

1. 模型上的數據註釋

   public class Blog
   {
       public int BlogId { get; set; }
       public string Url { get; set; }
   
       [NotMapped]
       public DateTime LoadedFromDatabase { get; set; }
   }
   

2. Fluent API覆蓋OnModelCreating

   class MyContext : DbContext
    {
        public DbSet<Blog> Blogs { get; set; }
   
        protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
            modelBuilder.Entity<Blog>()
            .Ignore(b => b.LoadedFromDatabase);
        }
    }
   
    public class Blog
    {
        public int BlogId { get; set; }
        public string Url { get; set; }
   
        public DateTime LoadedFromDatabase { get; set; }
    }
