XmlObjectSerializer.IsStartObject Method (XmlReader)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Gets a value that specifies whether the XmlReader is positioned over an XML element that can be read.

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

Syntax

'Declaration
Public Overridable Function IsStartObject ( _
    reader As XmlReader _
) As Boolean

public virtual bool IsStartObject(
    XmlReader reader
)

Parameters

Return Value

Type: System.Boolean
true if the reader is positioned over the starting element; 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. To return true, the found element must have an expected name. The actual expected element name depends on the implementation of the serializer.

With the DataContractSerializer, the starting element is specified in the constructor of the extension class. For an example, see the constructors for the DataContractSerializer class.
