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.
So my question is, is there an attribute or something I can use to make the DataContractSerializer
ignore a property?
To ignore individual properties, use the [JsonIgnore] attribute. You can specify conditional exclusion by setting the [JsonIgnore] attribute's Condition property. The JsonIgnoreCondition enum provides the following options: Always - The property is always ignored.
It is not future-proof for small changes If you mark your classes as [Serializable] , then all the private data not marked as [NonSerialized] will get dumped. You have no control over the format of this data. If you change the name of a private variable, then your code will break.
Serialization is the process of converting an object into a stream of bytes to store the object or transmit it to memory, a database, or a file. Its main purpose is to save the state of an object in order to be able to recreate it when needed. The reverse process is called deserialization.
Here are some examples of using serialization: - Storing data in an object-oriented way to files on disk, e.g. storing a list of Student objects. - Saving program's states on disk, e.g. saving state of a game. - Sending data over the network in form objects, e.g. sending messages as objects in chat application.
You might be looking for IgnoreDataMemberAttribute
.
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.
So, it depends on how you've decorated your class as to how to keep a member from serializing:
[DataContract]
, then remove the [DataMember]
for the property.[Serializable]
, then add [NonSerialized]
in front of the field for the property.[IgnoreDataMember]
to the property.If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
