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"> <UserModel>  <Id>1</Id>  <Name>name</Name>  <Gender>0</Gender>  <Age>20</Age>  <UserName>userName</UserName>  <Password>password</Password> </UserModel> <UserModel>  <Id>1</Id>  <Name>name</Name>  <Gender>0</Gender>  <Age>20</Age>  <UserName>userName</UserName>  <Password>password</Password> </UserModel> <UserModel>  <Id>1</Id>  <Name>name</Name>  <Gender>0</Gender>  <Age>20</Age>  <UserName>userName</UserName>  <Password>password</Password> </UserModel> <UserModel>  <Id>1</Id>  <Name>name</Name>  <Gender>0</Gender>  <Age>20</Age>  <UserName>userName</UserName>  <Password>password</Password> </UserModel> <UserModel>  <Id>1</Id>  <Name>name</Name>  <Gender>0</Gender>  <Age>20</Age>  <UserName>userName</UserName>  <Password>password</Password> </UserModel> <UserModel>  <Id>1</Id>  <Name>name</Name>  <Gender>0</Gender>  <Age>20</Age>  <UserName>userName</UserName>  <Password>password</Password> </UserModel> <UserModel>  <Id>1</Id>  <Name>name</Name>  <Gender>0</Gender>  <Age>20</Age>  <UserName>userName</UserName>  <Password>password</Password> </UserModel> <UserModel>  <Id>1</Id>  <Name>name</Name>  <Gender>0</Gender>  <Age>20</Age>  <UserName>userName</UserName>  <Password>password</Password> </UserModel> <UserModel>  <Id>1</Id>  <Name>name</Name>  <Gender>0</Gender>  <Age>20</Age>  <UserName>userName</UserName>  <Password>password</Password> </UserModel> <UserModel>  <Id>1</Id>  <Name>name</Name>  <Gender>0</Gender>  <Age>20</Age>  <UserName>userName</UserName>  <Password>password</Password> </UserModel></ArrayOfUserModel>
