C# SerializationException 类型“未标记为可序列化” - 但它是

SerializationException Type "is not marked as serializable" - But it is

提问by jp2code

In Windows Forms, .NET Framework 4.0, I am trying to Serialize an instance of a class I wrote.

在 Windows 窗体、.NET Framework 4.0 中，我试图序列化我编写的类的实例。

The class is marked as Serializable, but the form that uses the class (obviously) is not.

该类被标记为 Serializable，但使用该类的表单（显然）不是。

I do not want to Serialize an instance of the form. I want to Serialize the data I have in my class.

我不想序列化表单的实例。我想序列化我在课堂上的数据。

Everything in my class is marked as Serializable, so why am I still getting the SerializationException?

我的类中的所有内容都标记为 Serializable，那么为什么我仍然收到 SerializationException？

This is the BrazierPayobject that is used in the class above:

这是在BrazierPay上面的类中使用的对象：

[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; }
}

I even marked this enumerated type as Serializable (though, it should not need it):

我什至将此枚举类型标记为 Serializable（不过，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
}

I needed to set a NonSerializedAttributefor the EventHandler.

我需要NonSerializedAttribute为EventHandler设置一个。

The event delegate could not be serialized in the class (see Delegates and Serialization).

无法在类中序列化事件委托（请参阅委托和序列化）。

Marking the field as NonSerializedAttributewas as easy as it sounds.

标记该领域就像NonSerializedAttribute听起来一样简单。

From my code, I simply added this line:

从我的代码中，我只是添加了这一行：

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

This is something you can run into with any JSON serialization, including Web API in MVC 4.

这是任何 JSON 序列化都会遇到的问题，包括 MVC 4 中的 Web API。

I found this post to be very helpful when I was getting a serialization except on a const int value. Any const value needs to be marked with the same attribute as in Nick Freeman's answer:

我发现这篇文章在我获得序列化时非常有帮助，除了 const int 值。任何 const 值都需要使用与 Nick Freeman 的回答中相同的属性进行标记：

[field: NonSerializedAttribute]
const int iCantBeSerialized = 1;

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

Had the same problem, the PropertyChanged EventHandler of my serializable NotifyObject base class was subscribed by some viewmodels which went into the serialization queue therefore. Adding the NonSerializedAddtribute to this EventHandler saved my day. :-)

有同样的问题，我的可序列化 NotifyObject 基类的 PropertyChanged EventHandler 被一些视图模型订阅，因此进入序列化队列。将 NonSerializedAddtribute 添加到这个 EventHandler 拯救了我的一天。:-)
