XmlReader..::.ReadContentAsObject Method

Reads the text content at the current position as an Object.

Namespace: System.Xml
Assembly: System.Xml (in System.Xml.dll)

Syntax

Visual Basic (Declaration)

Public Overridable Function ReadContentAsObject As Object

Visual Basic (Usage)

Dim instance As XmlReader
Dim returnValue As Object

public virtual Object ReadContentAsObject()

Visual C++

virtual Object^ ReadContentAsObject()

JScript

Return Value

Type: System..::.Object
The text content as the most appropriate common language runtime (CLR) object.

Exceptions

Exception	Condition
InvalidCastException	The attempted cast is not valid.
FormatException	The string format is not valid.

Remarks

This method concatenates text, white space, significant white space, and CDATA sections, and skips any comments or processing instructions. Entity references are automatically resolved.

If the content is typed, the reader returns a boxed CLR of the most appropriate type, specified by the ValueType property. If the content is a list type, the reader returns an array of boxed objects of the appropriate type.

Note:
If a validation error occurs while parsing the content and the reader is an XmlReader object created by the Create method, the reader returns the content as a string. In other words when a validation error or warning occurs, the content is considered to be untyped.

If the content is not typed, the reader returns the content as a string.

The following table describes how this method treats each node type.

XmlNodeType	Return value	Reader behavior
Text CDATA Whitespace SignificantWhitespace EntityReference EndEntity	Concatenated content of text, CDATA, white space and significant white space nodes converted to the requested type.	Moves to the next start element or end element tag. Entity references are automatically expanded.
Attribute	Same as calling XmlConvert.ToXxx on the attribute value.	The reader remains in the current position
Comment ProcessingInstruction	Ignores the processing instruction (PI) or comment and reads the concatenated text content that follows the PI or comment.	Moves to the next start element or end element tag. Entity references are automatically expanded.
EndElement	The value of the element if the reader is a schema validating reader (ValidationType is set to Schema); otherwise an empty string.	The reader remains in the current position.
Element XmlDeclaration None Document DocumentType Notation Entity DocumentFragment	An InvalidOperationException is thrown.	Undefined, although typically the reader remains in the current position.
