我正在尝试了解如何使用序列化，以前从未使用过它。
现在我的单例对象（Main类）中有一个populate方法，它基本上使用我的addMember方法将一些成员对象添加到成员列表中
我想序列化此成员列表一旦我可以序列化和反序列化列表，我就可以删除我的填充方法。
问题
如何序列化此列表，以便在启动时反序列化成员列表？
我在哪里专门序列化？我在创建新成员时是序列化，还是在关机时序列化列表并在启动时反序列化。
由于可以编辑成员信息，如何序列化更新并覆盖以前保存的数据？
代码列表
我对序列化有点新意，但这是我的代码，我正在使用一种方法，因为我觉得这样更干净，在我的主类中使用ISerializable。这是我的主要课程的一些片段，请记住我的代码中有大量的评论，这就是为什么我之前没有发布这个：

}
这是Serializer类中的Serialization方法：
public void SerializeObject(string filename, object objectToSerialize)
{
Stream stream = File.Open(filename + ".bin", FileMode.Create);
BinaryFormatter bFormatter = new BinaryFormatter();
bFormatter.Serialize(stream, objectToSerialize);
stream.Close();
}
问题是，我不知道如何实际使用它。
还有一个反序列化器：
public HillRacing DeSerializeObject(string filename)
{
HillRacing hillracing;
Stream stream = File.Open(filename + ".bin", FileMode.Open);
BinaryFormatter bFormatter = new BinaryFormatter();
hillracing = (HillRacing)bFormatter.Deserialize(stream);
stream.Close();
return hillracing;
}
答案 0 :(得分：0)
虽然你已完成了大部分内容，但我建议使用一些小的泛型作为
public static class StreamUtilities
{
public static T GetObject<T>(Byte[] rawimage) where T : class
{
try
{
MemoryStream memStream = new MemoryStream();
BinaryFormatter binForm = new BinaryFormatter();
memStream.Write(rawimage, 0, rawimage.Length);
memStream.Seek(0, SeekOrigin.Begin);
return binForm.Deserialize(memStream) as T;
}
catch (Exception ex)
{
return null;
}
}
public static Byte[] Serialize<T>(this T obj) where T:class
{
if (obj == null)
return null;
BinaryFormatter bf = new BinaryFormatter();
MemoryStream ms = new MemoryStream();
bf.Serialize(ms, obj);
return ms.ToArray();
}
}
然后在你的主类或者你希望它使用include到命名空间，然后使用上面的扩展方法
Object1 a=new Object1();// any serializable object
serializedbytes=a.Serialize<Object1>();
//deserialize
Object b=StreamUtilities.GetObject<Object1>(serializedbytes);
上述扩展方法将允许对任何可序列化的对象进行序列化/反序列化。
