XmlReader.Create Method (String, XmlReaderSettings, XmlParserContext)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Creates a new XmlReader instance using the specified URI, XmlReaderSettings, and XmlParserContext objects.

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

Syntax

'Declaration
Public Shared Function Create ( _
    inputUri As String, _
    settings As XmlReaderSettings, _
    inputContext As XmlParserContext _
) As XmlReader

public static XmlReader Create(
    string inputUri,
    XmlReaderSettings settings,
    XmlParserContext inputContext
)

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 nulla null reference (Nothing in Visual Basic), a new XmlXapResolver object is used. For more information, see the Remarks section below.
  • inputContext
    Type: System.Xml.XmlParserContext
    The XmlParserContext object that provides 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 nulla null reference (Nothing in Visual Basic).

Return Value

Type: System.Xml.XmlReader
An XmlReader object to read XML data.

Exceptions

Exception Condition
NullReferenceException

The inputUri value is nulla 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.

Remarks

The inputUri parameter contains the URI to the XML file. This file must be located in the application's XAP resource, unless the XmlResolver has been changed to something other than XmlXapResolver. If you want to download the file from some other location, you must do the following:

  1. Download the data. To do this, initiate an asynchronous request by using HttpWebRequest.

  2. Create an XmlReader by calling one of the Create overloads that take Stream as a parameter and pass the returned Stream that contains the data..

For a code example, see How to: Load an XML File from an Arbitrary URI Location with LINQ to XML.
