Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.

With the given XmlReader, check if it is currently pointing to a serialized ModelElement instance that this serializer can handle. If so, create an instance of the ModelElement in the given Partition; otherwise return NULL. Note: The caller will guarantee that the reader is positioned at open XML tag of the element being read. This method should not move the reader; the reader should remain at the same position when this method returns.

abstract member TryCreateInstance : Microsoft.VisualStudio.Modeling.SerializationContext * System.Xml.XmlReader * Microsoft.VisualStudio.Modeling.Partition -> Microsoft.VisualStudio.Modeling.ModelElement

Public Overridable Function TryCreateInstance (serializationContext As SerializationContext, reader As XmlReader, partition As Partition) As ModelElement

Parameters

serializationContext: SerializationContext

Serialization context.

reader: XmlReader

XmlReader to read from.

partition: Partition

Partition in which the new element will be created.

Returns

ModelElement

The created ModelElement instance, or null if the reader is not pointing to a correct serialized instance.

Remarks

Note: that this method only tries to create the ModelElement instance, without actually deserializing it. The deserialization will be done by the Read() methods. There are two reasons for this separation: 1) We may need to link the created ModelElement to its parent element (through embedding relationship) before we can deserializing it properly. 2) The deserialization can be customized.
