XmlReader.Create Method (String)
Creates a new XmlReader instance with specified URI.
Assembly: System.Xml (in System.Xml.dll)
The inputUri value is a null reference (Nothing in Visual Basic).
The XmlReader does not have sufficient permissions to access the location of the XML data.
The file identified by the URI does not exist.
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. 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.
