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>
