XmlReader.ReadElementContentAsBoolean Method

Definition

Namespace:

System.Xml

Assembly:

System.Xml.ReaderWriter.dll

Reads the current element value as a Boolean object.

Overloads

ReadElementContentAsBoolean(String, String)	Checks that the specified local name and namespace URI matches that of the current element, then reads the current element and returns the contents as a Boolean object.
ReadElementContentAsBoolean()	Reads the current element and returns the contents as a Boolean object.

ReadElementContentAsBoolean(String, String)

Source:

XmlReader.cs

Checks that the specified local name and namespace URI matches that of the current element, then reads the current element and returns the contents as a Boolean object.

public:
 virtual bool ReadElementContentAsBoolean(System::String ^ localName, System::String ^ namespaceURI);

public virtual bool ReadElementContentAsBoolean (string localName, string namespaceURI);

abstract member ReadElementContentAsBoolean : string * string -> bool
override this.ReadElementContentAsBoolean : string * string -> bool

Public Overridable Function ReadElementContentAsBoolean (localName As String, namespaceURI As String) As Boolean

Parameters

localName

String

The local name of the element.

namespaceURI

String

The namespace URI of the element.

Returns

Boolean

The element content as a Boolean object.

Exceptions

InvalidOperationException

The XmlReader is not positioned on an element.

-or-

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."

XmlException

The current element contains child elements.

-or-

The element content cannot be converted to the requested type.

ArgumentNullException

The method is called with null arguments.

ArgumentException

The specified local name and namespace URI do not match that of the current element being read.

Remarks

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 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.
