源中授权状态的实现表明授权状态应该是可序列化的，但是当我尝试序列化授权状态以存储在我的身份验证票中时，我收到一个错误，指出该实现需要一个无参数的构造函数。

从引用的源中截取：

[Serializable]
public class AuthorizationState : IAuthorizationState {
    ...
    public AuthorizationState(IEnumerable<string> scopes = null) {

我如何获得状态：

var Authorization = Client.ProcessUserAuthorization();

我如何尝试序列化状态：

    public string Serialize(IAuthorizationState objectInstance)
    {
        var serializer = new XmlSerializer(objectInstance.GetType());
        var sb = new StringBuilder();

        using (TextWriter writer = new StringWriter(sb))
        {
            serializer.Serialize(writer, objectInstance);
        }

        return sb.ToString();
    }

我运行了一个快速控制台应用程序

class Program
{
    static void Main(string[] args)
    {
        var can = new CanSerialize();
        var cant = new CantSerialize();

        var ser1 = can.Serialize();
        var ser2 = cant.Serialize();
    }
}

[Serializable]
public class CantSerialize
{
    public int id { get; set; }
    public CantSerialize(int ID = 1)
    {
        id = ID;
    }

    public string Serialize()
    {
        var serializer = new XmlSerializer(this.GetType());
        var sb = new StringBuilder();

        using (TextWriter writer = new StringWriter(sb))
        {
            serializer.Serialize(writer, this);
        }

        return sb.ToString();
    }

}

[Serializable]
public class CanSerialize
{
    public int id { get; set; }
    private CanSerialize()
    {
        id = 1;
    }
    public CanSerialize(int ID = 1)
    {
        id = ID;
    }

    public string Serialize()
    {
        var serializer = new XmlSerializer(this.GetType());
        var sb = new StringBuilder();

        using (TextWriter writer = new StringWriter(sb))
        {
            serializer.Serialize(writer, this);
        }

        return sb.ToString();
    }
}

实现可以有一个默认的无参数构造函数吗？如示例所示，如果担心拥有公共 ctor，它可以是私有的。

同时，我将创建一个数据传输对象来在我的授权令牌和状态之间来回传送信息。

编辑：我发现 JSON.net 转换效果很好：

var a = JsonConvert.SerializeObject(Authorization);
var b = JsonConvert.DeserializeObject(a, typeof(AuthorizationState));
