XPathNavigator.ValueAsLong Property

Definition

Namespace:

System.Xml.XPath

Assemblies:

netstandard.dll, System.Xml.ReaderWriter.dll

Source:

XPathNavigator.cs

Gets the current node's value as an Int64.

C#

public override long ValueAsLong { get; }

Property Value

Int64

The current node's value as an Int64.

Exceptions

FormatException

The current node's string value cannot be converted to a Int64.

InvalidCastException

The attempted cast to Int64 is not valid.

Examples

For an example of the ValueAsLong property, see the ValueAsBoolean property.

Remarks

If the XPathNavigator has schema or type information (for example, from an XmlDocument object initialized with an XML schema validating XmlReader), and if the current node is defined as an XML Schema xs:integer type, the ValueAsLong property returns the current node's value as an unboxed Int64 object.

However, if the XPathNavigator does not have any schema or type information, the ValueAsLong property attempts to convert the string value of the current node to a Int64 value, according to the XPath 2.0 casting rules for xs:integer.
