C# 有继承权的数据契约？

我有一个类，其中包含序列化和反序列化的对象列表：

[DataContract]
public class Manager
{
  [DataMember]
  public BigBase[] enemies;
}

包含子类的类：

[DataContract]
[KnownType(typeof(Medium))]
[KnownType(typeof(Small))]
public class BigBase
{
    [DataMember]
    public bool isMoving;
}
[DataContract]
public class Medium : BigBase
{
}
[DataContract]
public class Small: BigBase
{
}

---

现在奇怪的是，当反序列化敌人数组时，它将包含正确反序列化的BigBase类，但每个中小型类都没有正确的isMoving值。

您需要在

管理器上设置
KnownType
属性：

[DataContract]
[KnownType(typeof(Medium))]
[KnownType(typeof(Small))]
public class Manager
{
  [DataMember]
  public BigBase[] enemies;
}

因为管理器有一个
BigBase
数组，其元素也可能是派生类。因此，
DataContractSerializer
将知道在序列化和反序列化
Manager
对象时从数组中期望得到什么（并且都是
DataMember
）

我在这个测试代码中没有看到这一点。我认为你的序列化代码是错误的

电话样本：

Manager test = new Manager();

            Medium medium = new Medium() {isMoving = true,Name = "medium", UpgradedName = "mediaum name"};
            //some items in array
            test.enemies = new BigBase[] {medium,new Small{isMoving = false},new Small{isMoving = true}, new BigBase {Name = "bigbase", isMoving = true}, new BigBase {Name = "bigbase2", isMoving = true}, new BigBase {Name = "bigbase3", isMoving = true}} ;

            DataContractSerializer serializer = new DataContractSerializer(typeof (Manager));
            FileStream writer = new FileStream("test123.txt", FileMode.Create);
            serializer.WriteObject(writer, test);
            writer.Close();
            writer = new FileStream("test123.txt", FileMode.Open);
            Manager deserializedmanager = serializer.ReadObject(writer) as Manager;
            //verify serialized object
            Console.WriteLine("medium object:"+ (deserializedmanager.enemies[0]  as Medium).UpgradedName);

如果没有一些示例测试代码，我怀疑是否有人愿意帮助您。
Manager test = new Manager();

            Medium medium = new Medium() {isMoving = true,Name = "medium", UpgradedName = "mediaum name"};
            //some items in array
            test.enemies = new BigBase[] {medium,new Small{isMoving = false},new Small{isMoving = true}, new BigBase {Name = "bigbase", isMoving = true}, new BigBase {Name = "bigbase2", isMoving = true}, new BigBase {Name = "bigbase3", isMoving = true}} ;

            DataContractSerializer serializer = new DataContractSerializer(typeof (Manager));
            FileStream writer = new FileStream("test123.txt", FileMode.Create);
            serializer.WriteObject(writer, test);
            writer.Close();
            writer = new FileStream("test123.txt", FileMode.Open);
            Manager deserializedmanager = serializer.ReadObject(writer) as Manager;
            //verify serialized object
            Console.WriteLine("medium object:"+ (deserializedmanager.enemies[0]  as Medium).UpgradedName);
