Resolves the entity reference for EntityReference nodes.
Assembly: System.Xml (in System.Xml.dll)
If the reader is positioned on an EntityReference node (XmlNodeType.EntityReference), if Read is called after calling this method, the entity replacement text is parsed. When the entity replacement text is finished, an EndEntity node is returned to close the entity reference scope.
After calling this method, if the entity is part of an attribute value, you must call ReadAttributeValue to step into the entity.
