从MemoryStream()反序列化

本文关键字：反序列化 MemoryStream | 更新日期: 2023-09-27 18:15:14

假设我有一个类，里面有对象

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

我正在尝试使用序列化接口

来序列化它
[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，但是当我试图反序列化它时，它给了我错误

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"Class_Serialization。没有找到SerializeThisClass。"}系统。异常{System.Runtime.Serialization.SerializationException}

从MemoryStream()反序列化

如果您正在实现ISerializable，则需要签名的构造函数:

protected YourType(SerializationInfo information, StreamingContext context) {}

加载数据(基本上与GetObjectData相反)。大概，使用(未测试):

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

尝试添加构造函数:

protected SerializeThisClass(SerializationInfo info, StreamingContext context)
{
}
