c# - 反序列化时传入对象引用

Question

我有一个反序列化的对象:

public object DeSerializeObject(string filename)
        {
            object objectToSerialize;
            Stream stream = File.Open(filename, FileMode.Open);
            BinaryFormatter bFormatter = new BinaryFormatter();
            objectToSerialize = (object)bFormatter.Deserialize(stream);
            stream.Close();
            return objectToSerialize;
        }

---

    public GUI_Settings(SerializationInfo info, StreamingContext ctxt)
    {
        PrinterFont = (Font)info.GetValue("_printFont", typeof(Font));
    }

我如何在反序列化时传入和对象？有点像这样

public object DeSerializeObject(string filename, someObject thing)
            {
                ......
                objectToSerialize = (object)bFormatter.Deserialize(stream, thing);
                .....
            }

---

public GUI_Settings(SerializationInfo info, StreamingContext ctxt, someObject thing)
        {

            PrinterFont = (Font)info.GetValue("_printFont", typeof(Font));
            _thing = thing;
        }

我不太确定我是否解释清楚让我再试一次。

在我的主课里面我说

_settings = (GUI_Settings)new ObjectSerializing()
    .DeSerializeObject("Settings.data");

或者如果我理解 Jalal Aldeen Saa 所说的话

_settings = (GUI_Settings)ObjectSerializing
    .DeserializeFromFile<GUI_Settings>("Settings.data");

当代码运行时，我需要向它发送对 _backend 类型 backEndInitializer 的引用。这个引用保存在这个主类中。 GUI_Settings 是我反序列化的类型。 _backend 是我需要发送 GUI_Settings() 方法使用的引用。

答案:

public static object DeSerializeObject(string filename, backEndInitializer backend)
    {
    object state = backend; // your object

    System.Runtime.Serialization.Formatters.Binary.BinaryFormatter bFormatter =
        new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter(
            null,
            new System.Runtime.Serialization.StreamingContext(
                System.Runtime.Serialization.StreamingContextStates.All,
                state)); // pass it in

    object objectToSerialize;
    Stream stream = File.Open(filename, FileMode.Open);
    //BinaryFormatter bFormatter = new BinaryFormatter();
    objectToSerialize = (object)bFormatter.Deserialize(stream);
    stream.Close();
    return objectToSerialize;
}

然后在反序列化的类中

public GUI_Settings(SerializationInfo info, StreamingContext ctxt)
        {
            _backend = (backEndInitializer) ctxt.Context;
}

Answer 1

        object state = null; // your object

        System.Runtime.Serialization.Formatters.Binary.BinaryFormatter formatter = 
            new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter(
                null, 
                new System.Runtime.Serialization.StreamingContext(
                    System.Runtime.Serialization.StreamingContextStates.All, 
                    state)); // pass it in

从那里您可以在反序列化构造函数的上下文参数中访问 it 对象。 StreamingContext 将引用此实例
