CustomPropertyDescriptorSerializer.TryCreateDerivedInstance Method

This method creates a correct derived instance of CustomPropertyDescriptor based on the tag currently pointed by the reader. Note that the difference between this method and the above one is that this method will never create an instance of the CustomPropertyDescriptor type itself, only derived types are checked.

Parameters

• serializationContext
  Type: Microsoft.VisualStudio.Modeling.SerializationContext

  Serialization context.

• reader
  Type: System.Xml.XmlReader

  XmlReader to read serialized data from.

• partition
  Type: Microsoft.VisualStudio.Modeling.Partition

  Partition in which new elements should be created.

Return Value

Type: Microsoft.VisualStudio.Modeling.ElementLink
Created instance that derives from CustomPropertyDescriptor, or null if the reader is not pointing to such a serialized instance.

Remarks

The caller will guarantee that the reader is positioned at open XML tag of the next element being read. This method should not move the reader; the reader should remain at the same position when this method returns.
