) As XmlReader


Type: System.String

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

Exception Condition

The inputUri value is null.


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


The XmlReaderSettings.NameTable and XmlParserContext.NameTable properties both contain values. (Only one of these NameTable properties can be set and used).


The file specified by the URI cannot be found.


The URI format is not correct.

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 you’re solution targets the.NET Framework 4.5.2, specify an XmlResolver using the XmlReaderSettings.XmlResolver property.

This means that the XmlReader can access any locations that does not require authentication. 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 restrict the resources that the XmlReader can access by setting the XmlResolver property to an XmlSecureResolver object.

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