ReadElementContentAsBoolean Method

XmlReader.ReadElementContentAsBoolean Method ()


Reads the current element and returns the contents as a Boolean object.

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

public virtual bool ReadElementContentAsBoolean()

Return Value

Type: System.Boolean

The element content as a Boolean object.

Exception Condition

The XmlReader is not positioned on an element.


The current element contains child elements.


The element content cannot be converted to a Boolean object.


The method is called with null arguments.


An XmlReader method was called before a previous asynchronous operation finished. In this case, InvalidOperationException is thrown with the message “An asynchronous operation is already in progress.”

This method reads the start tag, the contents of the element, and moves the reader past the end element tag. It expands entities and ignores processing instructions and comments. The element can only contain simple content. That is, it cannot have child elements.

If the element content is typed xsd:boolean, the reader returns an unboxed Boolean object. If the content is not typed xsd:boolean, the reader attempts to convert it to a Boolean object according to the rules defined by the W3C XML Schema Part 2: Datatypes recommendation.
