Create Method (Stream)

XmlReader.Create Method (Stream)


Creates a new XmlReader instance using the specified stream with default settings.

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

public static XmlReader Create(
	Stream input


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.

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.


The XmlReader does not have sufficient permissions to access the location of the XML data.

An XmlReaderSettings object with default settings is used to create the reader. If you wish to specify the features to support on the created reader, use the overload that takes an XmlReaderSettings object as one of its arguments, and pass in an XmlReaderSettings object with the correct settings.

A default 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, specify an XmlResolver with the necessary credentials using the XmlReaderSettings.XmlResolver property.

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

The following example creates an XmlReader object that reads from a FileStream.

FileStream fs = new FileStream(@"C:\data\books.xml", FileMode.OpenOrCreate, 
                                                                    FileAccess.Read, FileShare.Read);

// Create the XmlReader object.
XmlReader reader = XmlReader.Create(fs);
