Preventing serialization of properties in VB.NET
There are two ways to prevent serialization of properties in VB.NET:
Use the NonSerializedAttribute attribute
The NonSerializedAttribute attribute is a custom attribute that can be applied to properties to prevent them from being serialized. To use the N onSerializedAttribute attribute, simply apply it to the property that you want to prevent from being serialized.
For example, the following code shows how to use the NonSerializedAttribute attribute to prevent the Password property from being serialized:
If you serialize a Person object using the XmlSerializer class, the Password property will not be serialized.
Use a custom serialization implementation
If you need more control over how your objects are serialized, you can create your own custom serialization implementation. To do this, you must implement the ISerializable interface.
The ISerializable interface defines two methods: GetObjectData() and OnDeserialization(). The GetObjectData() method is used to serialize the object, and the OnDeserialization() method is used to deserialize the object.
In the GetObjectData() method, you can manually specify which properties of the object to serialize. To do this, you can use the SerializationInfo.AddValue() method. For example, the following code shows how to implement a custom serialization for the Person class:
This code will only serialize the Password property of the Person object.
Once you have implemented the ISerializable interface, you can serialize the object using the XmlSerializer class. To do this, simply pass the object to the XmlSerializer class's Serialize() method.
For example, the following code shows how to serialize a Person object using the XmlSerializer class:
This code will create a new XML file called person.xml that contains the serialized Person object.
You can prevent the serialization of properties by marking them with the NonSerialized attribute. This attribute excludes specific properties from the serialization process, ensuring that sensitive or non-essential data is not included when serializing an object. It is useful for maintaining data privacy, security, or optimizing serialization performance.
