使用带有ISO-8859-1编码的XmlTextWriter编写XML文件

using System;
using System.IO;
using System.Text;
using System.Xml;

class Program
{
    static void Main(string[] args)
    {
        // 创建一个XmlTextWriter对象
        XmlTextWriter writer = new XmlTextWriter("example.xml", Encoding.GetEncoding("ISO-8859-1"));

        // 设置文档的属性
        writer.Formatting = Formatting.Indented;
        writer.Indentation = 2;

        // 开始编写XML文档
        writer.WriteStartDocument();

        // 编写根元素
        writer.WriteStartElement("root");

        // 编写子元素
        writer.WriteStartElement("child");
        writer.WriteAttributeString("id", "1");
        writer.WriteString("Hello, world!");
        writer.WriteEndElement();

        // 结束编写XML文档
        writer.WriteEndElement();
        writer.WriteEndDocument();

        // 关闭XmlTextWriter对象
        writer.Close();
    }
}
