c# - How to prevent auto implemented properties from being serialized?

Question

How can I prevent a auto implemented property from being serialized by the binary formatter? The [NonSerialized] attribute can only be used with fields. And the field is hidden when using auto implemented properties.

Answer 1

It′s not supported for auto implemented properties. You have to use a backing field and set the NonSerializedAttribute on it.

public class ClassWithNonSerializedProperty {

  [NonSerialized]
  private object _data;  // Backing field of Property Data that is not serialized

  public object Data{
    get { return _data; }
    set { _data = value; }
  }
}
