EF代码优先：从通用基类继承，WEB api失去基属性

Question

I would like to use the following as a base class for all my classes:

[DataContract(IsReference = true)]
public abstract class EsBase
{
    [DatabaseGenerated(System.ComponentModel.DataAnnotations.Schema.DatabaseGeneratedOption.Identity)]
    public Guid ID { get; set; }

    public bool SoftDelete { get; set; }
}

With example child class:

public class Match : EsBase
{                
    [Display(Name = "Start time")]
    public DateTime StartTime { get; set; }
}

Problem is that when Match object is sent out through WEB API I do not have access to ID or SoftDelete.

How to pass these as well into output?

Answer 1

Just add [DataMember] attribute to the properties of your DataContract class. This then makes those properties become part of the serialization of your DataContract object.
