总结：创建了XmlWriterSettings对象的一个实例，然后设置各种属性，如Indent,ConformanceLevel,IndentChars和OmitXmlDeclaration.
XmlWriterSettings settings = new XmlWriterSettings();
settings.Indent = true;
settings.ConformanceLevel = ConformanceLevel.Auto;
settings.IndentChars = "\t";
settings.OmitXmlDeclaration = false;
然 后将XmlWriterSettings对象作为一个参数传入XmlWriter对象的Create()方法中，并将XmlWriterSettings 对象的设置的应用于新创建的XmlWriter对象。以上就是利用XmlWriterSettings对象来控制由XmlWriter对象创建的Xml文 件输出的所有操作。
