Gets the current node's value as an Int64.

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

public:
property long long ValueAsLong {
	virtual long long get() override;
}

Property Value

Type: System::Int64

The current node's value as an Int64.

Exception Condition
FormatException

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

InvalidCastException

The attempted cast to Int64 is not valid.

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.

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