WCF中继承了实体类，怎么对其序列化

我有个实体类 public class terminal
{
public int ID { get; set; }

public string termNO { get; set; }
}
在WCF服务中继承了它
[DataContract]
public class term : terminal
{

}

这个要不要序列化，如果需要，怎么去序列化

[DataContract(IsReference=true)]
public class Student
{
public Student()
{
this.Teachers = new HashSet();
}

[DataMember]
public int ID { get; set; }
[DataMember]
public virtual string Name { get; set; }
[DataMember]
public virtual ICollection Teachers { get; set; }
}

[DataContract(IsReference = true)]
public class Teacher
{
[DataMember]
public int ID { get; set; }
[DataMember]
public virtual string Name { get; set; }
}

有传输/保存的要求就需要序列化。直接给基类加[Serializable()] 特性就行了

[DataContract] public class term : terminal { [DataMember] public int ID { get; set; } [DataMember] public string termNO { get; set; } }

截止至.net 4.0总共有如下若干个序列化类 1.xml序列化 xmlserializer 2.二进制序列化 binaryformatter 3.soap序列化 soapformatter 4.wcf序列化 datacontractserializer 5.json序列化 datacontractjsonserializer和javascriptserializer

[DataContract] [KnownType(typeof(term))] public class terminal { public int ID { get; set; } public string termNO { get; set; } } [不用加DataContract] public class term : terminal { }
