OnDeserializingAttribute Class

When applied to a method, specifies that the method is called during deserialization of an object.

Namespace: System.Runtime.Serialization
Assembly: mscorlib (in mscorlib.dll)

[AttributeUsageAttribute(AttributeTargets::Method, Inherited=false)] 
[ComVisibleAttribute(true)] 
public ref class OnDeserializingAttribute sealed : public Attribute
/** @attribute AttributeUsageAttribute(AttributeTargets.Method, Inherited=false) */ 
/** @attribute ComVisibleAttribute(true) */ 
public final class OnDeserializingAttribute extends Attribute
AttributeUsageAttribute(AttributeTargets.Method, Inherited=false) 
ComVisibleAttribute(true) 
public final class OnDeserializingAttribute extends Attribute
Not applicable.

Use the OnDeserializingAttribute to set default values during deserialization. For example, if the type that you are deserializing does not contain a constructor, create a method to set values of any fields in the instance and apply the attribute to the method.

To use the OnDeserializingAttribute, the method must contain a StreamingContext parameter. The attribute marks the method to be called by the serialization infrastructure and the StreamingContext provides additional data about the type of serialization taking place. The usage is shown in the following code:

\\ C#
[OnDeserializingAttribute()]
internal void RunThisMethod(StreamingContext context)
{ 
    // Code not shown.
}
' Visual Basic
<OnDeserializingAttribute()> _
Private Sub RunThisMethod(context As StreamingContext)
    ' Code not shown.
End Sub
NoteNote:

In your code, you can use the word OnDeserializing instead of the longer OnDeserializingAttribute.

The following example applies the OnDeserializedAttribute, OnSerializingAttribute, OnSerializedAttribute, and OnDeserializingAttribute attributes to methods in a class.

No code example is currently available or this language may not be supported.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
