Parameters

localName

The local name of the element.

namespaceURI

The namespace URI of the element.

Return Value

The element content as a 64-bit signed integer.

Exception typeCondition

InvalidOperationException

The XmlReader is not positioned on an element.

XmlException

The current element contains child elements.

-or-

The element content cannot be converted to a 64-bit signed integer.

ArgumentNullException

The method is called with a null reference (Nothing in Visual Basic) arguments.

ArgumentException

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

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:long, the reader returns an unboxed 64-bit signed integer. If the content is not typed xsd:long, the reader attempts to convert it to a 64-bit signed integer according to the rules defined by the W3C XML Schema Part 2: Datatypes recommendation.
