C#将反序列化构造函数调用为默认构造函数的INSTEAD

Question

我刚刚熟悉C#中对象的序列化。我想知道反序列化构造函数是被称为默认构造函数的INSTEAD OF还是IN ADDITION TO。如果是IN ADDITION TO，这些调用的顺序是什么？例如：

[Serializable()]
public class ReadCache : ISerializable
{
    protected ArrayList notifiedURLs;
    // Default constructor
    public ReadCache()
    {
        notifiedURLs = new ArrayList();
    }
    // Deserialization constructor.
    public ReadCache(SerializationInfo info, StreamingContext ctxt)
    {
        //Get the values from info and assign them to the appropriate properties
        notifiedURLs = (ArrayList)info.GetValue("notifiedURLs", typeof(ArrayList));
    }
}

Answer 1

不，它将被称为"而不是"默认值，但您可以用这样的东西初始化您的列表：

public ReadCache(SerializationInfo info, StreamingContext ctxt)
  : this()
{
    //Get the values from info and assign them to the appropriate properties
    notifiedURLs = (ArrayList)info.GetValue("notifiedURLs", typeof(ArrayList));
}

请注意"…：this（）"语法-但在您的特殊情况下，您不必这样做！
