Public methodSupported by the XNA FrameworkSupported by Portable Class LibraryXmlWriterSettingsInitializes a new instance of the XmlWriterSettings class.
Top

  NameDescription
Public propertyAsyncGets or sets a value that indicates whether asynchronous XmlWriter methods can be used on a particular XmlWriter instance.
Public propertySupported by the XNA FrameworkSupported by Portable Class LibraryCheckCharactersGets or sets a value that indicates whether the XML writer should check to ensure that all characters in the document conform to the "2.2 Characters" section of the W3C XML 1.0 Recommendation.
Public propertySupported by the XNA FrameworkSupported by Portable Class LibraryCloseOutputGets or sets a value indicating whether the XmlWriter should also close the underlying stream or TextWriter when the Close method is called.
Public propertySupported by the XNA FrameworkSupported by Portable Class LibraryConformanceLevelGets or sets the level of conformance that the XML writer checks the XML output for.
Public propertyDoNotEscapeUriAttributesGets or sets a value that indicates whether the XmlWriter does not escape URI attributes.
Public propertySupported by the XNA FrameworkSupported by Portable Class LibraryEncodingGets or sets the type of text encoding to use.
Public propertySupported by the XNA FrameworkSupported by Portable Class LibraryIndentGets or sets a value indicating whether to indent elements.
Public propertySupported by the XNA FrameworkSupported by Portable Class LibraryIndentCharsGets or sets the character string to use when indenting. This setting is used when the Indent property is set to true.
Public propertySupported by Portable Class LibraryNamespaceHandlingGets or sets a value that indicates whether the XmlWriter should remove duplicate namespace declarations when writing XML content. The default behavior is for the writer to output all namespace declarations that are present in the writer's namespace resolver.
Public propertySupported by the XNA FrameworkSupported by Portable Class LibraryNewLineCharsGets or sets the character string to use for line breaks.
Public propertySupported by the XNA FrameworkSupported by Portable Class LibraryNewLineHandlingGets or sets a value indicating whether to normalize line breaks in the output.
Public propertySupported by the XNA FrameworkSupported by Portable Class LibraryNewLineOnAttributesGets or sets a value indicating whether to write attributes on a new line.
Public propertySupported by the XNA FrameworkSupported by Portable Class LibraryOmitXmlDeclarationGets or sets a value indicating whether to omit an XML declaration.
Public propertySupported by the XNA FrameworkOutputMethodGets the method used to serialize the XmlWriter output.
Public propertyWriteEndDocumentOnCloseGets or sets a value that indicates whether the XmlWriter will add closing tags to all unclosed element tags when the Close method is called.

The Create method is the preferred mechanism for obtaining XmlWriter instances. The Create method uses the XmlWriterSettings class to specify which features to implement in the XmlWriter object that is created.

NoteNote

If you're using the XmlWriter object with the Transform method, you should use the OutputSettings property to obtain an XmlWriterSettings object with the correct settings. This ensures that the created XmlWriter object has the correct output settings.

The XmlWriterSettings class provides properties that control data conformance and output format.

For data conformance checks and auto-corrections, use these properties:

Property

Specifies

Value

Default

CheckCharacters

Whether to check that characters are in the legal XML character set, as defined by W3C.

true or false

true

ConformanceLevel

Whether to check that output is a well-formed XML 1.0 document or fragment.

ConformanceLevel.Document (document-level), Fragment (fragment-level), or Auto (auto-detection)

ConformanceLevel.Document (document-level conformance)

WriteEndDocumentOnClose

Whether to add closing tags to all unclosed elements when the Close method is called.

true or false

true

To specify output format, use these properties:

Property

Specifies

Value

Default

Encoding

Text encoding to use.

System.Text.Encoding value

Encoding.UTF8

Indent

Whether to indent elements

true or false

false (no indentation)

IndentChars

Character string to use when indenting (used when Indent is set to true).

String

Two spaces

NewLineChars

Character string to use for line breaks.

String

\r\n (carriage return, line feed)

NewLineHandling

How to handle newline characters.

System.Xml.NewLineHandling value: Entitize (normalize), Replace (replace), or None (leave unchanged)

Replace (replace with characters specified by NewLineChars)

NewLineOnAttributes

Whether to write attributes on individual lines (has no effect when Indent is false).

true or false

false

OmitXmlDeclaration

Whether to write an XML declaration.

true or false

false

The following example creates an XmlWriter that writes to an XML file and writes each attribute on a new line.

XmlWriterSettings settings = new XmlWriterSettings();
settings.Indent = true;
settings.OmitXmlDeclaration = true;
settings.NewLineOnAttributes = true;

writer = XmlWriter.Create(Console.Out, settings);

writer.WriteStartElement("order");
writer.WriteAttributeString("orderID", "367A54");
writer.WriteAttributeString("date", "2001-05-03");
writer.WriteElementString("price", "19.95");
writer.WriteEndElement();
	
writer.Flush();

The sample produces the following output:

<order
  orderID="367A54"
  date="2001-05-03">
  <price>19.95</price>
</order>
