Parameters

inputUri
Type: System.String

The URI for the file that contains the XML data. The XmlUrlResolver class is used to convert the path to a canonical data representation.

Return Value

Type: System.Xml.XmlReader

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

The inputUri value is null.

UriFormatException
System_CAPS_noteNote

In the .NET for Windows Store apps or the Portable Class Library, catch the base class exception, FormatException, instead.

The URI format is not correct.

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.

System_CAPS_importantImportant

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 XML data file specified by the URI.

// Create the XmlReader object.
XmlReader reader = XmlReader.Create("books.xml");
