XmlReader.Create Method (String, XmlReaderSettings)

Creates a new instance with the specified URI and XmlReaderSettings.

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

public static XmlReader Create(
	string inputUri,
	XmlReaderSettings settings
)

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 null, a new XmlUrlResolver object is used.
settings
Type: System.Xml.XmlReaderSettings
The XmlReaderSettings object used to configure the new XmlReader instance. This value can be null.

Return Value

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

ExceptionCondition
ArgumentNullException

The inputUri value is null.

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.

The following example creates an XmlReader object that supports document type definition (DTD) validation.


// Set the validation settings.
XmlReaderSettings settings = new XmlReaderSettings();
settings.DtdProcessing = DtdProcessing.Parse;
settings.ValidationType = ValidationType.DTD;
settings.ValidationEventHandler += new ValidationEventHandler (ValidationCallBack);

 // Create the XmlReader object.
XmlReader reader = XmlReader.Create("itemDTD.xml", settings);

// Parse the file. 
while (reader.Read()) {}
