测试代码如下
对TypeC序列化后再反序列化，结果发现里面collection全为null，这是为什么呢？
有什么办法可以解决吗？
[Serializable]
struct TypeA
{
public double A1;
public double A2;
public double A3;
public TypeA(double a)
{
A1 = a;
A2 = a;
A3 = a;
}
}
[Serializable]
class TypeB : ISerializable
{
private readonly List<TypeA> collection = new List<TypeA>();
public TypeB()
{
collection.Add(new TypeA(1));
collection.Add(new TypeA(2));
collection.Add(new TypeA(3));
collection.Add(new TypeA(4));
collection.Add(new TypeA(5));
}
#region ISerializable Members
protected TypeB(SerializationInfo info, StreamingContext context)
{
collection.AddRange(info.GetValue("B", typeof(List<TypeA>)) as List<TypeA>);
}
public void GetObjectData(SerializationInfo info, StreamingContext context)
{
info.AddValue("B", collection, typeof(List<TypeA>));
}
#endregion
}
[Serializable]
class TypeC : ISerializable
{
private readonly List<TypeB> collection = new List<TypeB>();
public TypeC()
{
collection.Add(new TypeB());
collection.Add(new TypeB());
collection.Add(new TypeB());
}
protected TypeC(SerializationInfo info, StreamingContext context)
{
collection.AddRange(info.GetValue("C", typeof(TypeB[])) as TypeB[]);
}
public void GetObjectData(SerializationInfo info, StreamingContext context)
{
info.AddValue("C", collection.ToArray());
}
}
class Program
{
static void Main(string[] args)
{
using(MemoryStream stream = new MemoryStream())
{
TypeC c = new TypeC();
BinaryFormatter formatter = new BinaryFormatter();
formatter.Serialize(stream, c);
stream.Seek(0, SeekOrigin.Begin);
// 反序列化后，结果与预期不一致
TypeC c2 = formatter.Deserialize(stream) as TypeC;
}
using(MemoryStream stream = new MemoryStream())
{
TypeB b = new TypeB();
BinaryFormatter formatter = new BinaryFormatter();
formatter.Serialize(stream, b);
stream.Seek(0, SeekOrigin.Begin);
TypeB b2 = formatter.Deserialize(stream) as TypeB;
}
using(MemoryStream stream = new MemoryStream())
{
TypeB[] b = new TypeB[2];
b[0] = new TypeB();
b[1] = new TypeB();
BinaryFormatter formatter = new BinaryFormatter();
formatter.Serialize(stream, b);
stream.Seek(0, SeekOrigin.Begin);
TypeB[] b2 = formatter.Deserialize(stream) as TypeB[];
}
}
}
