XmlReader.ReadContentAsObject Method

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

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

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

Syntax

'Declaration
Public Overridable Function ReadContentAsObject As Object

public virtual Object ReadContentAsObject()

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.

NoteNote:

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.
