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://HdhCmsTestw3.org/2001/XMLSchema-instance" xmlns:xsd = "http://HdhCmsTestw3.org/2001/XMLSchema" >
< UserModel >
< Id >1</ Id >
< Name >name</ Name >
< Gender >0</ Gender >
< Age >20</ Age >
< UserName >userName</ UserName >
< Password >password</ Password >
</ UserModel >
