XmlTextWriter.Indentation プロパティ
Formatting を Formatting.Indented に設定するときに、階層構造のレベルごとに書き込む IndentChar の数を取得または設定します。
Public Property Indentation As Integer
[C#]
public int Indentation {get; set;}
[C++]
public: __property int get_Indentation();public: __property void set_Indentation(int);
[JScript]
public function get Indentation() : int;public function set Indentation(int);
プロパティ値
各レベルの IndentChar の数。既定値は 2 です。
例外

解説
インデントは、DocumentType、Element、Comment、ProcessingInstruction、CDATASection の各ノード型に対して実行されます。その他のノード型は影響を受けません。 XmlTextWriter は、内部 DTD サブセットにインデント幅を適用しません。ただし、次を実行すると、内部 DTD サブセットに書式設定を適用できます。
String name = "Employees";
String pubid = null;
String sysid = null;
String subset =
@"
<!ELEMENT Employees (Employee)+>
<!ELEMENT Employee EMPTY>
<!ATTLIST Employee firstname CDATA #REQUIRED>
<!ENTITY Company 'Microsoft'>]>
";
XmlTextWriter tw = new XmlTextWriter(Console.Out);
tw.WriteDocType(name, pubid, sysid, subset);
