C# Class Mvp.Xml.Common.XPath.XPathDocumentWriter

XmlWriter that can produce an XPathDocument without the need to parse XML.
Using this writer whenever you need to perform fast chained transformations. Using this class avoids reparsing of the intermediate output, yielding lower memory and CPU usage.

Future versions of XPathDocument may offer this functionality out of the box.

Important: this class requires unrestricted member access reflection permissions in order to run. If the Mvp.Xml assembly is installed in the GAC, it will run without problems. The Mvp.Xml allows partially trusted callers, so only this assembly needs to be GAC'ed.

Alternatively, you can configure .NET security policy to allow the appropriate permission (see ReflectionPermission, PermissionState.Unrestricted and ReflectionPermissionFlag.MemberAccess).

Méthodes protégées

Méthode Description
Dispose ( bool disposing ) : void

Never disposes the underlying writer as it's not keeping in-memory state.

This override also avoids an exception that is thrown otherwise by the base System.Xml.XmlRawWriter being used internally.
