[英]C# Serialization of nested classes
我想序列化一個對象。 我有這個基本的類結構:
class Controller
{
Clock clock;
public event EventHandler<ClockChangedEventArgs> ClockChanged;
public void serializeProperties()
{
using (FileStream stream = new FileStream(PROPERTIES_FILE, FileMode.Append, FileAccess.Write, FileShare.Write))
{
IFormatter formatter = new BinaryFormatter();
try
{
formatter.Serialize(stream, clock);
}
catch (Exception e)
{
Console.WriteLine(e.Message);
}
}
}
public void deserializeProperties()
{
using (FileStream stream = new FileStream(PROPERTIES_FILE, FileMode.OpenOrCreate, FileAccess.Read, FileShare.Read))
{
IFormatter formatter = new BinaryFormatter();
try
{
clock = (Clock)formatter.Deserialize(stream);
}
catch (Exception e)
{
Console.WriteLine(e.Message);
clock = new Clock();
}
finally
{
clock.ClockChanged += new EventHandler<ClockChangedEventArgs>(clock_ClockChanged);
}
}
}
}
Clock類的定義如下:
[Serializable]
public class Clock
{
ClockProperties[] properties;
int current;
bool isAnimated;
public event EventHandler<ClockChangedEventArgs> ClockChanged;
public Clock()
{
properties = new ClockProperties[2];
properties[0] = new ClockProperties("t1");
properties[1] = new ClockProperties("t2");
properties[0].ValueChanged += new EventHandler(Clock_ValueChanged);
properties[1].ValueChanged += new EventHandler(Clock_ValueChanged);
}
}
基礎ClockProperties:
[Serializable]
public class ClockProperties
{
public event EventHandler ValueChanged;
int posX, posY;
string clock;
public ClockProperties(string name)
{
clock = name;
}
public void OnValueChanged(EventArgs e)
{
if (ValueChanged != null)
{
ValueChanged(this, e);
}
}
public string Clock
{
get { return clock; }
set {
if (!value.Equals(clock))
{
clock = value;
OnValueChanged(EventArgs.Empty);
}
}
}
public int PosX
{
get { return posX; }
set {
if (!(value == posX))
{
posX = value;
OnValueChanged(EventArgs.Empty);
}
}
}
public int PosY
{
get { return posY; }
set {
if (!(value == posY))
{
posY = value;
OnValueChanged(EventArgs.Empty);
}
}
}
}
當我嘗試使用包含的ClockProperties
數組序列化Clock
對象時,我得到一個異常,即Controller
未標記為可序列化。 老實說,我不明白為什么。 我假設我只序列化Clock
對象,因此只將該類和ClockProperties
標記為Serializable
。 我錯過了什么嗎?
在類Clock中標記ClockChangedEvent [field:NonSerialized]
時鍾上的事件可能是您的問題,因為它是對Controller的引用。 這是一個眾所周知的“問題” 。
您需要使事件或其支持字段不可序列化,您應該沒問題。
