本文實例講述了C#實現導出List數據到xml文件的方法。分享給大家供大家參考，具體如下：
C#導出List數據到xml文件，這里主要用到的是：
XmlSerializer 類 (System.Xml.Serialization)
將對象序列化到 XML 文檔中和從 XML 文檔中反序列化對象。XmlSerializer 使您得以控制如何將對象編碼到 XML 中。
實體類代碼：
/// <summary>/// 用戶實體類////// 注意：類的訪問修飾符必須是：public，否則會出現錯誤：/// 因其保護級別而不可訪問。只能處理公共類型。/// </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; } }}導出代碼：
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("寫入文件成功！"); } } catch (System.Exception ex) { System.Console.WriteLine("===================================="); System.Console.WriteLine(ex.Message); System.Console.WriteLine(ex.StackTrace); }}生成的XML文件內容：
<?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>
