C#导出List数据到xml文件[附源码]
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"?>
