在XElement.ToString结果中的XAttributes之间输入换行符/回车符

Question

是否无法在XElement.ToString生成的xml字符串中的属性之间显示换行符？

以下不起作用 - 它保留了换行符,但是将它们放在所有属性之下,所以只有4/5个空行:

new XElement("options", new XText("\r\n"),
    new XAttribute("updated", Updated.XmlTime()), new XText("\r\n"),
    new XAttribute("color", Color), new XText("\r\n"),
    new XAttribute("puppies", Puppies), new XText("\r\n"),
    new XAttribute("isTrue", IsTrue), new XText("\r\n"),
    new XAttribute("kitties", Kitties ?? "")),

你可以用一个XmlWriter.试试这个:

public static string ToStringFormatted(this XElement xml)
{
  XmlWriterSettings settings = new XmlWriterSettings();
  settings.Indent = true;
  settings.NewLineOnAttributes = true;
  StringBuilder result = new StringBuilder();
  using (XmlWriter writer = XmlWriter.Create(result, settings)) {
    xml.WriteTo(writer);
  }
  return result.ToString();
} // ToStringFormatted

然后

var xml =new XElement("options",
    new XAttribute("updated", "U"),
    new XAttribute("color", "C"),
    new XAttribute("puppies", "P"),
    new XAttribute("isTrue", "I"),
    new XAttribute("kitties", "K")
 );
 Console.WriteLine(xml.ToStringFormatted());

产生这个:

<options
  updated="U"
  color="C"
  puppies="P"
  isTrue="I"
  kitties="K" />

您可以使用各种XmlWriterSettings属性进行不同的格式设置.
