Programmatically set properties to exclude from serialization

Question

Is it possible to programmatically set that you want to exclude a property from serialization?

Example:

• When de-serializing, I want to load up an ID fi

Answer 1

If you are serializing to XML, you can use XMLIgnore

As in:

class SomeClass
{
  [XmlIgnore] int someID;
  public string someString;
}

Answer 2

If you want to include field during serialization but ignore it during deserialization then you can use OnDeserializedAttribute to run a method which will set default value for ID field.

Answer 3

The NonSerializedAttribute attribute.

Answer 4

If you're using XML serialization, use the [XmlIgnore] attribute. Otherwise, how to ignore a particular property is defined by the serializer itself.

Answer 5

I believe there are three options here:

1. Use XmlIgnore attribute. The downside is that you need to know in advance which properties you want the xmlserializer to ignore.

2. Implement the IXmlSerializable interface. This gives you complete control on the output of XML, but you need to implement the read/write methods yourself.

3. Implement the ICustomTypeDescriptor interface. I believe this will make your solution to work no matter what type of serialization you choose, but it is probably the lengthiest solution of all.

An old post, but I found ShouldSerialize pattern http://msdn.microsoft.com/en-us/library/53b8022e%28VS.71%29.aspx That is really HELPFUL!!!
