XmlWriter类可以把XML写入一个流，文件，StringBuilder，TextWriter或另一个XmlWriter对象中。代码：

 1XmlWriterSettings settings = new XmlWriterSettings();
 2//是否缩进
 3settings.Indent = true;
 4//属性是否在新行
 5settings.NewLineOnAttributes = true;
 6XmlWriter writer = XmlWriter.Create("booknew.xml", settings);
 7writer.WriteStartDocument();
 8writer.WriteStartElement("book");
 9writer.WriteAttributeString("genre", "Mystery");
10writer.WriteAttributeString("publicationdate", "2001");
11writer.WriteAttributeString("ISBN", "123456789");
12writer.WriteElementString("title", "Case of the Missing Cookie");
13writer.WriteStartElement("author");
14writer.WriteElementString("name", "Cookie Monster");
15writer.WriteEndElement();
16writer.WriteElementString("price", "9.99");
17writer.WriteEndElement();
18writer.WriteEndDocument();
19writer.Flush();
20writer.Close();

运行后生成文件booknew.xml:

 1<?xml version="1.0" encoding="utf-8"?>
 2<book
 3  genre="Mystery"
 4  publicationdate="2001"
 5  ISBN="123456789">
 6  <title>Case of the Missing Cookie</title>
 7  <author>
 8    <name>Cookie Monster</name>
 9  </author>
10  <price>9.99</price>
11</book>
