本文给大家分享一下C#操作（读取、写入）XML文档的实用方法，这种方法主要是对比较规范的XML文档进行操作，因为它（XML文档）和类对象是严格对应的，否则在反序列或序列化的时候会出现错误。其他的不用多说，直接看示例代码吧：
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 = "张三", 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 = "赵六", 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) { //序列化对象生成文件 WriteSingleXml(); //反序列化文件生成对象 ReadListXml(); Console.ReadKey(); } /// <summary> /// 从XML文件中反序列化对象 /// </summary> private static void ReadListXml() { //反序列化文件 Console.WriteLine("反序列化XML文件为集合"); 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> /// 序列化对象到XML文件 /// </summary> private static void WriteSingleXml() { //序列化集合为xml文件 Console.WriteLine("序列化集合为XML文件"); var reader = new XmlSerializer(typeof(List<UserInfo>)); //写入文件 using (var fs = File.OpenWrite("UserInfo.xml")) { reader.Serialize(fs, list); } Console.WriteLine("写入成功"); } } }
运行结果如图：
生成的XML文档如下:
<"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>张三</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>赵六</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>
