.NET XML输出丢失换行符

using System;
using System.Xml;

class Program
{
    static void Main()
    {
        // 创建XmlWriterSettings对象并设置Indent属性
        XmlWriterSettings settings = new XmlWriterSettings();
        settings.Indent = true;

        // 创建XmlWriter对象并指定输出文件路径
        using (XmlWriter writer = XmlWriter.Create("output.xml", settings))
        {
            // 开始写入XML内容
            writer.WriteStartDocument();
            writer.WriteStartElement("root");
            writer.WriteElementString("element", "value");
            writer.WriteEndElement();
            writer.WriteEndDocument();
        }
    }
}

<?xml version="1.0" encoding="utf-8"?>
<root>
  <element>value</element>
</root>
