DataContractJsonSerializer.IsStartObject Method

Definition

Namespace:

System.Runtime.Serialization.Json

Assembly:

System.Runtime.Serialization.Json.dll

Gets a value that specifies whether the serializer can read the object.

Overloads

IsStartObject(XmlDictionaryReader)	Gets a value that specifies whether the XmlDictionaryReader is positioned over an XML element that represents an object the serializer can deserialize from.
IsStartObject(XmlReader)	Determines whether the XmlReader is positioned on an object that can be deserialized.

IsStartObject(XmlDictionaryReader)

Source:

DataContractJsonSerializer.cs

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

public:
 override bool IsStartObject(System::Xml::XmlDictionaryReader ^ reader);

public override bool IsStartObject (System.Xml.XmlDictionaryReader reader);

override this.IsStartObject : System.Xml.XmlDictionaryReader -> bool

Public Overrides Function IsStartObject (reader As XmlDictionaryReader) As Boolean

Parameters

reader

XmlDictionaryReader

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

Returns

Boolean

true if the reader is positioned correctly; otherwise, false.

Remarks

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.

IsStartObject(XmlReader)

Source:

DataContractJsonSerializer.cs

Determines whether the XmlReader is positioned on an object that can be deserialized.

public:
 override bool IsStartObject(System::Xml::XmlReader ^ reader);

public override bool IsStartObject (System.Xml.XmlReader reader);

override this.IsStartObject : System.Xml.XmlReader -> bool

Public Overrides Function IsStartObject (reader As XmlReader) As Boolean

Parameters

reader

XmlReader

The XmlReader used to read the XML stream.

Returns

Boolean

true if the reader is positioned correctly; otherwise, false.

Remarks

This method checks whether the reader is positioned on an element that can be deserialized, and returns true if it is. To return true, the found element must have the expected name.
