XmlReader.Create Method (String, XmlReaderSettings, XmlParserContext)

Creates a new XmlReader instance by using the specified URI, settings, and context information for parsing.

Namespace:  System.Xml
Assembly:  System.Xml (in System.Xml.dll)
static member Create : 
        inputUri:string * 
        settings:XmlReaderSettings * 
        inputContext:XmlParserContext -> XmlReader

Parameters

inputUri
Type: System.String

The URI for the file containing the XML data. The XmlResolver object on the XmlReaderSettings object is used to convert the path to a canonical data representation. If XmlResolver is a null reference (Nothing in Visual Basic), a new XmlUrlResolver object is used.

settings
Type: System.Xml.XmlReaderSettings

The settings for the new XmlReader instance. This value can be a null reference (Nothing in Visual Basic).

inputContext
Type: System.Xml.XmlParserContext

The context information required to parse the XML fragment. The context information can include the XmlNameTable to use, encoding, namespace scope, the current xml:lang and xml:space scope, base URI, and document type definition.

This value can be a null reference (Nothing in Visual Basic).

Return Value

Type: System.Xml.XmlReader
An object that is used to read the XML data in the stream.
ExceptionCondition
ArgumentNullException

The inputUri value is a null reference (Nothing in Visual Basic).

SecurityException

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

ArgumentException

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

FileNotFoundException

The file specified by the URI cannot be found.

UriFormatException

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. 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.

Security noteSecurity 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.
