Parameters

input
Type: System.IO.Stream

The stream that contains the XML data.

The settings for the new XmlReader instance. This value can be null.

inputContext
Type: System.Xml.XmlParserContext

The context information required to parse the XML fragment. The context information can include the XmlNameTable to use, encoding, namespace scope, the current xml:lang and xml:space scope, base URI, and document type definition.

This value can be null.

Return Value

Type: System.Xml.XmlReader
An object that is used to read the XML data in the stream.

By default an XmlUrlResolver with no credentials is used to access any external resources such as a document type definition (DTD), entities, schemas, and so on.

You can use one of the following methods to control which resources the XmlReader can access:

  • Do not allow the XmlReader to open any external resources by setting the XmlResolver property to null.
