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">
