See Also: XmlUrlResolver Members
XmlUrlResolver is used to resolve external XML resources such as entities, document type definitions (DTDs) or schemas. It is also used to process include and import elements found in Extensible StyleSheet Language (XSL) style sheets or XML Schema definition language (XSD) schemas.
XmlUrlResolver is the default resolver for all classes in the System.Xml namespace. It supports the file:// and http:// protocols and requests from the System.Net.WebRequest class.
System.Xml.XmlUrlResolver objects can contain sensitive information such as user credentials. You should be careful when you cache System.Xml.XmlUrlResolver objects and should not pass System.Xml.XmlUrlResolver objects to an untrusted component.
