我有一个用这个反序列化的对象:
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));
}
在反序列化时,我怎么能传入和反对呢?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;
}
我不太确定我是否清楚地解释了它让我再试一次。
我的主要课程内部我说
_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,我需要向它发送一个对_backend类型backEndInitializer的引用。此引用在此主类中。 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;
}
然后在正在反序列化的类中
public GUI_Settings(SerializationInfo info, StreamingContext ctxt)
{
_backend = (backEndInitializer) ctxt.Context;
}
答案 0 :(得分:4)
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context参数中访问它对象。 StreamingContext
将引用此实例

使用泛型传递将要反序列化的对象的类型:
public static T DeserializeFromFile<T>(string fileName) where T : class
{
using (FileStream stream = new FileStream(fileName, FileMode.Open, FileAccess.Read))
{
BinaryFormatter formatter = new BinaryFormatter();
return (T)formatter.Deserialize(stream);
}
}
用法:
Thing deserialized = DeserializeFromFile<Thing>(filePath);
