Question

让我们说，我有一个包含对象的类。

namespace Class_Serialization
{
    [Serializable]
    public class Data
    {
        public string Name = "Example1";
        public string place = "Torino";
        public DateTime time = DateTime.Now;
    }
}

我正在尝试使用ISerialization接口

序列化它

[Serializable]
public class SerializeThisClass : ISerializable
{
    public Data StreamThisData;

    public SerializeThisClass()
    {

    }

    public SerializeThisClass(Data _StreamThisData)
    {
        StreamThisData = _StreamThisData;
    }
    [SecurityPermission(SecurityAction.LinkDemand, Flags = SecurityPermissionFlag.SerializationFormatter)]
    void ISerializable.GetObjectData(SerializationInfo info, StreamingContext context)
    {
        info.AddValue("Object Data", StreamThisData);
    }
}

现在，当我使用下面的代码序列化时

Data DataToSerialize = new Data();
BinaryFormatter DataToBinary = new BinaryFormatter();
SerializeThisClass serialize = new SerializeThisClass(DataToSerialize);
SerializeIn SerializeInMem = new SerializeIn();
DataToBinary.Serialize(SerializeInMem.StreamOfData, serialize);
ListOfStreams.Add(SerializeInMem);

它正常序列化，但是当我尝试反序列化时，它会给我错误

BinaryFormatter BinaryToData = new BinaryFormatter();
foreach (SerializeIn x in ListOfStreams)
{
    x.StreamOfData.Position = 0;
    SerializeThisClass DeserializeData = (SerializeThisClass)BinaryToData.Deserialize(x.StreamOfData);
    MessageBox.Show("Name: " + DeserializeData.StreamThisData.Name + "\nPlace: " + DeserializeData.StreamThisData.place + "\nDateTime: " + DeserializeData.StreamThisData.time.ToString());
}

错误：$ exception {“反序列化类型对象的构造函数找不到'Class_Serialization.SerializeThisClass'。“} System.Exception {System.Runtime.Serialization.SerializationException}

Answer 1

如果您正在实施ISerializable，则需要签名的构造函数：

protected YourType(SerializationInfo information, StreamingContext context) {}

加载数据（基本上是GetObjectData的反向）。据推测，（未经测试）：

StreamThisData = (Data)info.GetValue("Object Data", typeof(Data));

尝试添加构造函数：

protected SerializeThisClass(SerializationInfo info, StreamingContext context)
{
}

从MemoryStream反序列化（）
