Dotnet Core 2未将属性与数据库列映射

Question

我试图将类中的某些属性与数据库中的模型进行映射，但是某些属性未映射，我不知道为什么。

结果是：

  

{“ cessionID”：5，“ contractID”：14，“ cessionTypeID”：1，“ cessionStatusID”：1，“ cessionDate”：“ 2018-06-25T00：00：00”，“ cessionTime”：“ 00 ：00：00“，” documentPath“：”文档“，” assignmentCost“：1000.0000，” note“：” note“，” tswUserID“：2486，” lastUpdate“：null}

如您所见，属性lastUpdate和属性cessionTime没有映射。

这是我的dbContext

 public class DataContext : DbContext
    {
        public DataContext(DbContextOptions<DataContext> options) : base(options)
        {

        }



        public DbSet<Cessions>Cessions { get; set; }



        protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
            modelBuilder.HasAnnotation("Relational:DefaultSchema", "VIDAMX\\davidmata");
            modelBuilder.Entity<Cessions>(entity =>
            {
                entity.HasKey(e => e.CessionID);

                entity.ToTable("Cessions", "dbo");

                entity.Property(e => e.CessionID).HasColumnName("CessionID");

                entity.Property(e => e.AssignmentCost)
                    .HasColumnType("money")
                    .HasDefaultValueSql("((0))");

                entity.Property(e => e.CessionDate)
                    .HasColumnType("date")
                    .HasDefaultValueSql("(getdate())");

                entity.Property(e => e.CessionStatusID).HasColumnName("CessionStatusID");

                entity.Property(e => e.CessionTime).HasDefaultValueSql("(getdate())").HasColumnName("CessionTime");

                entity.Property(e => e.CessionTypeID).HasColumnName("CessionTypeID");

                entity.Property(e => e.ContractID).HasColumnName("ContractID");



                entity.Property(e => e.DocumentPath)
                    .IsRequired()
                    .HasMaxLength(300)
                    .IsUnicode(false)
                    .HasDefaultValueSql("('')");

                entity.Property(e => e.LastUpdate)
                    .IsRequired()
                    .IsRowVersion();

                entity.Property(e => e.Note)
                    .IsRequired()
                    .HasMaxLength(2000)
                    .IsUnicode(false)
                    .HasDefaultValueSql("('')");

                entity.Property(e => e.TSWUserID).HasColumnName("TSWUserID");

                entity.HasOne(d => d.CessionStatus)
                    .WithMany(p => p.Cessions)
                    .HasForeignKey(d => d.CessionStatusID)
                    .OnDelete(DeleteBehavior.ClientSetNull)
                    .HasConstraintName("FK__Sessions__Sessio__398D8EEE");

                entity.HasOne(d => d.CessionTypes)
                    .WithMany(p => p.Cessions)
                    .HasForeignKey(d => d.CessionTypeID)
                    .OnDelete(DeleteBehavior.ClientSetNull)
                    .HasConstraintName("FK__Sessions__Sessio__38996AB5");
            });
        }
    }

这是我的Cession课程

public partial class Cessions
    {
        public Cessions()
        {
            Assignments = new HashSet<Assignments>();
            CessionDocuments = new HashSet<CessionDocuments>();
        }
        public int CessionID { get; set; }

        public int ContractID { get; set; }

        public int CessionTypeID { get; set; }

        public int CessionStatusID { get; set; }

        public DateTime CessionDate { get; set; }

        public TimeSpan CessionTime { get; set; }

        public string DocumentPath { get; set; }

        public decimal AssignmentCost { get; set; } //The decimal keyword indicates a 128-bit data type. Compared to floating-point types, the decimal type has more precision and a smaller range, which makes it appropriate for financial and monetary calculations.

        public string Note { get; set; }

        public int TSWUserID { get; set; }

        public byte[] LastUpdate { get; set; }


        public virtual CessionStatus CessionStatus { get; set; }
        public virtual CessionTypes CessionTypes { get; set; }
        public virtual ICollection<Assignments> Assignments { get; set; }
        public virtual ICollection<CessionDocuments> CessionDocuments { get; set; }
    }
