本文給大家分享一下C#操作（讀取、寫入）XML文檔的實用方法，這種方法主要是對比較規(guī)范的XML文檔進行操作，因為它（XML文檔）和類對象是嚴格對應的，否則在反序列或序列化的時候會出現錯誤。其他的不用多說，直接看示例代碼吧：
using System;using System.Collections.Generic;using System.IO;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Xml.Serialization;namespace _01XMLSerialize{ class Program { private static List<UserInfo> list = new List<UserInfo>() { new UserInfo() { Id = 1, UserName = "張三", UserPass = "FDASDFAS", Email = "zhangsan@163.com", RegTime = DateTime.Now }, new UserInfo() { Id = 2, UserName = "李四", UserPass = "FDASDFAS", Email = "lisi@163.com", RegTime = DateTime.Now }, new UserInfo() { Id = 3, UserName = "王五", UserPass = "FDASDFAS", Email = "wangwu@163.com", RegTime = DateTime.Now }, new UserInfo() { Id = 4, UserName = "趙六", UserPass = "FDASDFAS", Email = "zhaoliu@163.com", RegTime = DateTime.Now }, new UserInfo() { Id = 5, UserName = "田七", UserPass = "FDASDFAS", Email = "tianqi@163.com", RegTime = DateTime.Now }, new UserInfo() { Id = 6, UserName = "王八", UserPass = "FDASDFAS", Email = "wangba@163.com", RegTime = DateTime.Now } }; static void Main(string[] args) { //序列化對象生成文件 WriteSingleXml(); //反序列化文件生成對象 ReadListXml(); Console.ReadKey(); } /// <summary> /// 從XML文件中反序列化對象 /// </summary> private static void ReadListXml() { //反序列化文件 Console.WriteLine("反序列化XML文件為集合"); var reader = new XmlSerializer(typeof(List<UserInfo>)); using (var fs = File.OpenRead("UserInfo.xml")) { var result = reader.Deserialize(fs) as List<UserInfo>; result.ForEach(Console.WriteLine); } Console.WriteLine("反序列化成功"); } /// <summary> /// 序列化對象到XML文件 /// </summary> private static void WriteSingleXml() { //序列化集合為xml文件 Console.WriteLine("序列化集合為XML文件"); var reader = new XmlSerializer(typeof(List<UserInfo>)); //寫入文件 using (var fs = File.OpenWrite("UserInfo.xml")) { reader.Serialize(fs, list); } Console.WriteLine("寫入成功"); } }} 運行結果如圖：
生成的XML文檔如下:
<?xml version="1.0"?><ArrayOfUserInfo xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <UserInfo> <Id>1</Id> <UserName>張三</UserName> <UserPass>FDASDFAS</UserPass> <Email>zhangsan@163.com</Email> <RegTime>2016-04-21T09:15:58.5576551+08:00</RegTime> </UserInfo> <UserInfo> <Id>2</Id> <UserName>李四</UserName> <UserPass>FDASDFAS</UserPass> <Email>lisi@163.com</Email> <RegTime>2016-04-21T09:15:58.5576551+08:00</RegTime> </UserInfo> <UserInfo> <Id>3</Id> <UserName>王五</UserName> <UserPass>FDASDFAS</UserPass> <Email>wangwu@163.com</Email> <RegTime>2016-04-21T09:15:58.5576551+08:00</RegTime> </UserInfo> <UserInfo> <Id>4</Id> <UserName>趙六</UserName> <UserPass>FDASDFAS</UserPass> <Email>zhaoliu@163.com</Email> <RegTime>2016-04-21T09:15:58.5576551+08:00</RegTime> </UserInfo> <UserInfo> <Id>5</Id> <UserName>田七</UserName> <UserPass>FDASDFAS</UserPass> <Email>tianqi@163.com</Email> <RegTime>2016-04-21T09:15:58.5576551+08:00</RegTime> </UserInfo> <UserInfo> <Id>6</Id> <UserName>王八</UserName> <UserPass>FDASDFAS</UserPass> <Email>wangba@163.com</Email> <RegTime>2016-04-21T09:15:58.5576551+08:00</RegTime> </UserInfo></ArrayOfUserInfo>
以上就是本文的全部內容，希望對大家學習C#程序設計有所幫助。
