	Stream input,
	XmlReaderSettings settings,
	string baseUri


Type: System.IO.Stream

The stream that contains 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.

Type: System.Xml.XmlReaderSettings

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

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 object that is used to read the XML data in the stream.

Exception Condition

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.


Starting with the .NET Framework 4.5.2, no default XmlUrlResolver is provided. If your solution targets the .NET Framework 4.5.2 or later versions, specify an XmlResolver using the XmlReaderSettings.XmlResolver property.

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.

System_CAPS_security Security Note

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.

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