Namespace:  System.Xml
Assembly:  System.Xml (in System.Xml.dll)

public static XmlReader Create(
	Stream input,
	XmlReaderSettings settings,
	string baseUri
)

Parameters

input
Type: System.IO.Stream
The stream containing the XML data.
The XmlReader scans the first bytes of the stream looking for a byte order mark or other sign of encoding. When encoding is determined, the encoding is used to continue reading the stream, and processing continues parsing the input as a stream of (Unicode) characters.
settings
Type: System.Xml.XmlReaderSettings
The XmlReaderSettings object used to configure the new XmlReader instance. This value can be null.
baseUri
Type: System.String
The base URI for the entity or document being read. This value can be null.
Security Note   The base URI is used to resolve the relative URI of the XML document. Do not use a base URI from an untrusted source.

Return Value

Type: System.Xml.XmlReader
An XmlReader object to read XML data.

ExceptionCondition
ArgumentNullException

The input value is null.

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. If the external resource is located on a network resource that requires authentication, use the XmlReaderSettings.XmlResolver property to specify an XmlResolver with the necessary credentials.

Security noteSecurity Note

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

Restrict the resources that the XmlReader can access by setting the XmlResolver property to an XmlSecureResolver object.

-or-

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

The created XmlReader object expands entity references and performs XML normalization of new line characters.
