C#实现导出List数据到xml文件的方法【附demo源码下载】

本文实例讲述了c#实现导出list数据到xml文件的方法。分享给大家供大家参考，具体如下：

c#导出list数据到xml文件，这里主要用到的是：

xmlserializer 类 (system.xml.serialization)

将对象序列化到 xml 文档中和从 xml 文档中反序列化对象。xmlserializer 使您得以控制如何将对象编码到 xml 中。

实体类代码：

/// <summary>
/// 用户实体类
///
/// 注意：类的访问修饰符必须是：public，否则会出现错误：
/// 因其保护级别而不可访问。只能处理公共类型。
/// </summary>
[serializable]
public class usermodel
{
    private long id = 1;
    private string name = "name";
    private int gender = 0;
    private int age = 20;
    private string username = "username";
    private string password = "password";
    public long id
    {
      get { return id; }
      set { id = value; }
    }
    public string name
    {
      get { return name; }
      set { name = value; }
    }
    public int gender
    {
      get { return gender; }
      set { gender = value; }
    }
    public int age
    {
      get { return age; }
      set { age = value; }
    }
    public string username
    {
      get { return username; }
      set { username = value; }
    }
    public string password
    {
      get { return password; }
      set { password = value; }
    }
}

导出代码：

private void button1_click(object sender, eventargs e)
{
  try
  {
    list<usermodel> list = new list<usermodel>();
    list.add(new usermodel());
    list.add(new usermodel());
    list.add(new usermodel());
    list.add(new usermodel());
    list.add(new usermodel());
    list.add(new usermodel());
    list.add(new usermodel());
    list.add(new usermodel());
    list.add(new usermodel());
    list.add(new usermodel());
    using (system.io.stringwriter stringwriter = new stringwriter(new stringbuilder()))
    {
      xmlserializer xmlserializer = new xmlserializer(typeof(list<usermodel>));
      xmlserializer.serialize(stringwriter, list);
      filestream fs = new filestream("list_usermodel.xml", filemode.openorcreate);
      streamwriter sw = new streamwriter(fs);
      sw.write(stringwriter.tostring());
      sw.close();
      fs.close();
      messagebox.show("写入文件成功！");
    }
  }
  catch (system.exception ex)
  {
    system.console.writeline("====================================");
    system.console.writeline(ex.message);
    system.console.writeline(ex.stacktrace);
  }
}

生成的xml文件内容：

<?xml version="1.0" encoding="utf-16"?>
<arrayofusermodel xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:xsd="http://www.w3.org/2001/xmlschema">
