Namespace: System.Runtime.Serialization
Assembly: System.Runtime.Serialization (in System.Runtime.Serialization.dll)
Syntax
'Declaration
Public MustOverride Function IsStartObject ( _
reader As XmlDictionaryReader _
) As Boolean
public abstract bool IsStartObject(
XmlDictionaryReader reader
)
Parameters
- reader
Type: System.Xml.XmlDictionaryReader
An XmlDictionaryReader used to read the XML stream or document.
Return Value
Type: System.Boolean
true if the reader can read the data; otherwise, false.
Remarks
This method checks whether the reader is positioned on an element to read, and returns true if the element is the top-level element for the object found in the XML stream or document. The XmlObjectSerializer implementation determines when to return true. Implementations may check that they are positioned on an element or look for an expected element name. One implementation of the XmlObjectSerializer, the DataContractSerializer, checks that it is positioned on an element and also checks that the element name is the top-level expected name for the type currently being deserialized.
If required, additional attributes in the XML stream can be read while positioned on the top level element before reading XML content using the ReadObject method.
