编写CRLF [英] Writing CRLF

问题描述

我需要将回车符+换行符+制表符写入xml文件，这怎么可能?

I need to write a carriage return + line feed + tab to an xml file, how is this possible?

FileStream fs = new FileStream(_file, FileMode.Create);
            XmlTextWriter w = new XmlTextWriter(fs, null);
            w.WriteStartDocument();
            w.WriteStartElement("articles");
            w.WriteComment("This file was generated by the XmlTextWriter class");
            w.WriteChars... :confused:

推荐答案

您的意思是ControlChars.CrLf?

Environment.NewLine可以为您提供此功能.

Environment.NewLine gives you that.

我发现添加以下行会格式化我的 xml文件:

I found that adding the following lines formats my xml file:

 w.Formatting = Formatting.Indented;
w.Indentation = 5;

using System.IO;
namespace WriteToXML
{
    class Program
    {
        static void Main(string[] args)
        {
            string _path = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase);
            _path = _path.Substring(6, _path.Length - 6);
            string _file =  _path + "\\article.xml";
            FileStream fs = new FileStream(_file, FileMode.Create);
            XmlTextWriter w = new XmlTextWriter(fs, null);
            w.Formatting = Formatting.Indented;
            w.Indentation = 5;
            w.WriteStartDocument();
            w.WriteStartElement("articles");
            w.WriteComment("This file was generated by the XmlTextWriter class");
            //write content
            w.WriteStartElement("article");
            w.WriteStartElement("timestamp");
            w.WriteString(DateTime.Now.ToString());
            w.WriteEndElement();
            w.WriteStartElement("subject");
            w.WriteString("subject");
            w.WriteEndElement();
            w.WriteStartElement("body");
            w.WriteString("This is a test");
            w.WriteEndElement();
            w.WriteStartElement("entryID");
            w.WriteEndElement();
            w.WriteStartElement("deleted");
            w.WriteString("No");
            w.WriteEndElement();
            //close root element
            w.WriteEndElement();
            w.WriteEndDocument();
            w.Close();
        }
    }
}
