Question

在Windows Forms，.NET Framework 4.0中，我正在尝试序列化我编写的类的实例。

该类被标记为Serializable，但使用该类的表单（显然）不是。

我不想序列化表单的实例。我想序列化我班上的数据。

我班上的所有内容都标记为Serializable，为什么我仍然会收到SerializationException？

    }

}

这是上面类中使用的BrazierPay对象：

[Serializable()]
public class BrazierPay {
  float pay;
  public BrazierPay(float payLevel) {
    Dirty = false;
    pay = payLevel;
  }
  public float Value {
    get { return pay; }
    set {
      if (pay != value) {
        Dirty = true;
        pay = value;
      }
    }
  }
  public bool Dirty { get; set; }
  public string DollarValue { get { return string.Format("{0:C}", pay); } }
  public string Formatted { get { return string.Format("{0:F}", pay); } }
  public override string ToString() { return Formatted; }
}

我甚至将此枚举类型标记为Serializable（但是，它不应该需要它）：

[Serializable()]
public enum EnumeratedLevel {
  NA_Silver = Clicker.NA_Silver, // Color.Silver
  E_Orange = Clicker.E_Orange, // Color.Orange
  D_Yellow = Clicker.D_Yellow, // Color.Yellow
  C_Green = Clicker.C_Green, // Color.Lime
  B_Blue = Clicker.B_Blue, // Color.DodgerBlue
  A_Violet = Clicker.A_Violet, // Color.Violet
}

Answer 1

解决

我需要为 EventHandler 设置NonSerializedAttribute。

无法在课程中序列化事件代理（请参阅Delegates and Serialization）。

将字段标记为NonSerializedAttribute就像听起来一样简单。

从我的代码中，我只是添加了这一行：

[field:NonSerializedAttribute()]
public event EventHandler BrazierCuttoffChanged;

Answer 2

这可以用于任何JSON序列化，包括MVC 4中的Web API。

我发现这篇文章在我获得序列化时非常有用，除了const int值。任何const值都需要用与Nick Freeman的答案相同的属性标记：

[field: NonSerializedAttribute]
const int iCantBeSerialized = 1;

Answer 3

[field:NonSerializedAttribute()]
public event EventHandler BrazierCuttoffChanged;

出现同样的问题，我的可序列化NotifyObject基类的PropertyChanged EventHandler被一些进入序列化队列的视图模型订阅。将NonSerializedAddtribute添加到此EventHandler节省了我的一天。： - ）

Answer 4

将BrazierMatrix2标记为[Serializable]

SerializationException类型“未标记为可序列化” - 但它确实如此
