  • Reference

Definition

Namespace:
System.Runtime.Serialization
Assembly:
System.Runtime.Serialization.dll

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

Overloads

IsStartObject(XmlReader)

Determines whether the XmlReader is positioned on an object that can be deserialized using the specified reader.
IsStartObject(XmlDictionaryReader)

Determines whether the XmlDictionaryReader is positioned on an object that can be deserialized using the specified reader.

Remarks

This is equivalent to using the ReadObject method of the IFormatter interface.

IsStartObject(XmlReader)

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

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

An XmlReader that contains the XML to read.

Returns

Boolean

true if the reader is at the start element of the stream to read; otherwise, false.

Exceptions

ArgumentNullException

the reader is set to null.

Applies to

IsStartObject(XmlDictionaryReader)

Determines whether the XmlDictionaryReader is positioned on an object that can be deserialized using the specified reader.

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

An XmlDictionaryReader that contains the XML to read.

Returns

Boolean

true, if the reader is at the start element of the stream to read; otherwise, false.

Exceptions

ArgumentNullException

the reader is set to null.

Remarks

The IsStartObject determines whether it can read an object by examining the name and namespace of the XML element the reader is positioned at, and comparing the values to expected name and namespace. The expected name and namespace can be set with the following: the data contract name and namespace of the type passed into the constructor, or the rootName and rootNamespace values passed into the constructor (if present).

You can set the rootName and rootNamespace in the following constructors: NetDataContractSerializer.NetDataContractSerializer(String, String), NetDataContractSerializer.NetDataContractSerializer(XmlDictionaryString, XmlDictionaryString), and NetDataContractSerializer.NetDataContractSerializer(XmlDictionaryString, XmlDictionaryString, StreamingContext, Int32, Boolean, FormatterAssemblyStyle, ISurrogateSelector).
