DataContractJsonSerializer::IsStartObject Method (XmlDictionaryReader)

Gets a value that specifies whether the XmlDictionaryReader is positioned over an XML element that represents an object the serializer can deserialize from.

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

public:
virtual bool IsStartObject(
	XmlDictionaryReader^ reader
) override

Parameters

reader
Type: System.Xml::XmlDictionaryReader

The XmlDictionaryReader used to read the XML stream mapped from JSON.

Return Value

Type: System::Boolean
true if the reader is positioned correctly; otherwise, false.

The IsStartObject determines whether it can read a object by checking that it is positioned on an XML element. It also examines the name and namespace of the XML element that the reader is positioned at and compares the values to the expected name and namespace. The expected name can be set with the rootName value passed into the constructor (if present), or is "root" if absent. The expected namespace is the empty string.

Note that this method is intended for advanced scenarios when working with XML mapped from JSON.
