How can I ignore a property when serializing using the DataContractSerializer?
提问by NotDan
I am using .NET 3.5SP1 and DataContractSerializer to serialize a class. In SP1, they changed the behavior so that you don't have to include DataContract/DataMember attributes on the class and it will just serialize the entire thing. This is the behavior I am using, but now I need to ignore one property from the serializer. I know that one way to do this is to add the DataContract attribute to the class, and just put the DataMember attribute on all of the members that I want to include. I have reasons, though, that this will not work for me.
我正在使用 .NET 3.5SP1 和 DataContractSerializer 来序列化一个类。在 SP1 中，他们更改了行为，因此您不必在类中包含 DataContract/DataMember 属性，它只会序列化整个事物。这是我正在使用的行为，但现在我需要忽略序列化程序中的一个属性。我知道这样做的一种方法是将 DataContract 属性添加到类，并将 DataMember 属性放在我想要包含的所有成员上。不过，我有理由认为这对我不起作用。
So my question is, is there an attribute or something I can use to make the DataContractSerializer ignore a property?
所以我的问题是，是否有一个属性或什么东西可以用来让 DataContractSerializer 忽略一个属性？

What you are saying is in conflict with what it says in the MSDN library at this location:
您所说的与此位置的 MSDN 库中所说的内容相冲突：

I don't see any mention of the SP1 feature you mention.
我没有看到您提到的 SP1 功能的任何提及。

Additionally, DataContractSerializer will serialize items marked as [Serializable] and will also serialize unmarked types in .NET 3.5 SP1 and later, to allow support for serializing anonymous types.
此外，DataContractSerializer 将序列化标记为 [Serializable] 的项目，还将序列化 .NET 3.5 SP1 及更高版本中未标记的类型，以支持序列化匿名类型。
So, it depends on how you've decorated your class as to how to keep a member from serializing:
因此，这取决于您如何装饰类以防止成员序列化：
- If you used
[DataContract], then remove the[DataMember]for the property. - If you used
[Serializable], then add[NonSerialized]in front of the fieldfor the property. - If you haven't decorated your class, then you should add
[IgnoreDataMember]to the property.
- 如果您使用了
[DataContract]，则删除[DataMember]该属性的 。 - 如果您使用
[Serializable]，则[NonSerialized]在该属性的字段前添加。 - 如果你还没有装饰你的类，那么你应该添加
[IgnoreDataMember]到属性中。

Try marking the field with [NonSerialized()] attribute. This will tell the serializer to ignore the field.
尝试使用 [NonSerialized()] 属性标记该字段。这将告诉序列化程序忽略该字段。

In XML Serializing, you can use the [XmlIgnore] attribute (System.Xml.Serialization.XmlIgnoreAttribute) to ignore a property when serializing a class.
在 XML 序列化中，您可以使用 [XmlIgnore] 属性 (System.Xml.Serialization.XmlIgnoreAttribute) 在序列化类时忽略属性。
This may be of use to you (Or it just may be of use to anyone who found this question when attempting to find out how to ignore a property when Serializing in XML, as I was).
这可能对你有用（或者它可能对任何在尝试找出在 XML 中序列化时如何忽略属性时发现这个问题的人有用，就像我一样）。
