XPathNavigator.ValueAs(Type, IXmlNamespaceResolver) Method

Definition

Gets the current node's value as the Type specified, using the IXmlNamespaceResolver object specified to resolve namespace prefixes.

public:
 override System::Object ^ ValueAs(Type ^ returnType, System::Xml::IXmlNamespaceResolver ^ nsResolver);
public override object ValueAs (Type returnType, System.Xml.IXmlNamespaceResolver? nsResolver);
public override object ValueAs (Type returnType, System.Xml.IXmlNamespaceResolver nsResolver);
override this.ValueAs : Type * System.Xml.IXmlNamespaceResolver -> obj
Public Overrides Function ValueAs (returnType As Type, nsResolver As IXmlNamespaceResolver) As Object

Parameters

returnType
Type

The Type to return the current node's value as.

nsResolver
IXmlNamespaceResolver

The IXmlNamespaceResolver object used to resolve namespace prefixes.

Returns

The value of the current node as the Type requested.

Exceptions

The current node's value is not in the correct format for the target type.

The attempted cast is not valid.

Remarks

The ValueAs method attempts to convert the value of the current node to the .NET type, specified according to the XPath 2.0 rules for casting the current node's type.

The IXmlNamespaceResolver object is used to resolve namespace prefixes related to type conversions. For example, when converting an xs:QName to an xs:string.
