我首先使用Entity Framework 4.4代码(工厂模式)从现有Oracle视图中获取数据.这是我的实体类:

class Data
{
    [Required]
    [StringLength(50)]
    public String EmailAddress { get; set; }

    [Required]
    [StringLength(200)]
    public String FundName { get; set; }

    [Required]
    [DecimalPrecision(AllowedPrecision=15,AllowedScale=0)]
    public Decimal FundCode { get; set; }

    [StringLength(3)]
    public String BankCode { get; set; }
}

这是我的Map类

class DataMap : EntityTypeConfiguration<Data>
{
    public DataMap() : base()
    {
        // Properties
        Property(t => t.EmailAddress).HasColumnType("varchar2");
        Property(t => t.FundName;
        Property(t => t.FundCode
        Property(t => t.BankCode).HasColumnType("varchar2");
        // Table
        ToTable("VIEW_FD_EMAIL");
    }
}

这是我的上下文类

class OracleContext : DbContext
{
    static OracleDataEntities() …
