XPathNavigator.ValueAsDouble Property


The .NET API Reference documentation has a new home. Visit the .NET API Browser on docs.microsoft.com to see the new experience.

Gets the current node's value as a Double.

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

public override double ValueAsDouble { get; }

Property Value

Type: System.Double

The current node's value as a Double.

Exception Condition

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


The attempted cast to Double 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:double type, the ValueAsDouble property returns the current node's value as an unboxed Double object.

However, if the XPathNavigator does not have any schema or type information, the ValueAsDouble property attempts to convert the string value of the current node to a Double value, according to the XPath 2.0 casting rules for xsd:double.

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