Метод	Описание
AddVariable ( string name, object value ) : void	Adds the variable to the dynamic evaluation context. Value type conversion for XPath evaluation is as follows: CLR Type XPath type System.String XPathResultType.String System.Double (or types that can be converted to) XPathResultType.Number System.Boolean XPathResultType.Boolean System.Xml.XPath.XPathNavigator XPathResultType.Navigator System.Xml.XPath.XPathNodeIterator XPathResultType.NodeSet Others XPathResultType.Any See the topic "Compile, Select, Evaluate, and Matches with XPath and XPathExpressions" in MSDN documentation for additional information.
CompareDocument ( string baseUri, string nextbaseUri ) : int	Implementation equal to XsltContext.
Compile ( string xpath ) : XPathExpression	Shortcut method that compiles an expression using an empty navigator.
DynamicContext ( ) : System	Initializes a new instance of the DynamicContext class.
DynamicContext ( NameTable table ) : System	Initializes a new instance of the DynamicContext class with the specified NameTable.
DynamicContext ( XmlNamespaceManager context ) : System	Initializes a new instance of the DynamicContext class.
DynamicContext ( XmlNamespaceManager context, NameTable table ) : System	Initializes a new instance of the DynamicContext class.
LookupNamespace ( string prefix ) : string	Same as XmlNamespaceManager.
LookupPrefix ( string uri ) : string	Same as XmlNamespaceManager.
PreserveWhitespace ( XPathNavigator node ) : bool	Same as XsltContext.
ResolveFunction ( string prefix, string name, XPathResultType ArgTypes ) : IXsltContextFunction	See XsltContext. Not used in our implementation.
ResolveVariable ( string prefix, string name ) : IXsltContextVariable	Resolves the dynamic variables added to the context. See XsltContext.
