◆ Create() [1/12]

static SharedPtr< XmlReader > System::Xml::XmlReader::Create ( const SharedPtr< IO::Stream > &  input)
static

Creates a new XmlReader instance using the specified stream with default settings.

Parameters
inputThe stream that contains the XML data. The XmlReader scans the first bytes of the stream looking for a byte order mark or other sign of encoding. When encoding is determined, the encoding is used to continue reading the stream, and processing continues parsing the input as a stream of (Unicode) characters.
Returns
An object that is used to read the XML data in the stream.
Exceptions
ArgumentNullExceptionThe input value is nullptr.
SecurityExceptionThe XmlReader does not have sufficient permissions to access the location of the XML data.

◆ Create() [2/12]

static SharedPtr< XmlReader > System::Xml::XmlReader::Create ( const SharedPtr< IO::Stream > &  input,
const SharedPtr< XmlReaderSettings > &  settings 
)
static

Creates a new XmlReader instance with the specified stream and settings.

Parameters
inputThe stream that contains the XML data. The XmlReader scans the first bytes of the stream looking for a byte order mark or other sign of encoding. When encoding is determined, the encoding is used to continue reading the stream, and processing continues parsing the input as a stream of (Unicode) characters.
settingsThe settings for the new XmlReader instance. This value can be nullptr.
Returns
An object that is used to read the XML data in the stream.
Exceptions
ArgumentNullExceptionThe input value is nullptr.

◆ Create() [3/12]

static SharedPtr< XmlReader > System::Xml::XmlReader::Create ( const SharedPtr< IO::Stream > &  input,
SharedPtr< XmlReaderSettings settings,
const SharedPtr< XmlParserContext > &  inputContext 
)
static

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

Parameters
inputThe stream that contains the XML data. The XmlReader scans the first bytes of the stream looking for a byte order mark or other sign of encoding. When encoding is determined, the encoding is used to continue reading the stream, and processing continues parsing the input as a stream of (Unicode) characters.
settingsThe settings for the new XmlReader instance. This value can be nullptr.
inputContextThe 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 nullptr.
Returns
An object that is used to read the XML data in the stream.
Exceptions
ArgumentNullExceptionThe input value is nullptr.

◆ Create() [4/12]

static SharedPtr< XmlReader > System::Xml::XmlReader::Create ( const SharedPtr< IO::Stream > &  input,
SharedPtr< XmlReaderSettings settings,
const String baseUri 
)
static

Creates a new XmlReader instance using the specified stream, base URI, and settings.

Parameters
inputThe stream that contains the XML data. The XmlReader scans the first bytes of the stream looking for a byte order mark or other sign of encoding. When encoding is determined, the encoding is used to continue reading the stream, and processing continues parsing the input as a stream of (Unicode) characters.
settingsThe settings for the new XmlReader instance. This value can be nullptr.
baseUriThe base URI for the entity or document being read. This value can be nullptr. Security Note The base URI is used to resolve the relative URI of the XML document. Do not use a base URI from an untrusted source.
Returns
An object that is used to read the XML data in the stream.
Exceptions
ArgumentNullExceptionThe input value is nullptr.

◆ Create() [5/12]

static SharedPtr< XmlReader > System::Xml::XmlReader::Create ( const SharedPtr< IO::TextReader > &  input)
static

Creates a new XmlReader instance by using the specified text reader.

Parameters
inputThe text reader from which to read the XML data. A text reader returns a stream of Unicode characters, so the encoding specified in the XML declaration is not used by the XML reader to decode the data stream.
Returns
An object that is used to read the XML data in the stream.
Exceptions
ArgumentNullExceptionThe input value is nullptr.

◆ Create() [6/12]

static SharedPtr< XmlReader > System::Xml::XmlReader::Create ( const SharedPtr< IO::TextReader > &  input,
const SharedPtr< XmlReaderSettings > &  settings 
)
static

Creates a new XmlReader instance by using the specified text reader and settings.

Parameters
inputThe text reader from which to read the XML data. A text reader returns a stream of Unicode characters, so the encoding specified in the XML declaration isn't used by the XML reader to decode the data stream.
settingsThe settings for the new XmlReader. This value can be nullptr.
Returns
An object that is used to read the XML data in the stream.
Exceptions
ArgumentNullExceptionThe input value is nullptr.

◆ Create() [7/12]

settingsThe settings for the new XmlReader instance. This value can be nullptr.
inputContextThe 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 nullptr.
Returns
