序列化反序列化对象XML文件写入Sample[简单但是有代表性]

using System;

namespace XMLTextWriter
{
        /// <summary>
        /// The class for <see cref="EmployeeData"/> that 
        /// represents a record in the <c>Employee</c> table.
        /// </summary>
        public class EmployeeData
        {
            Private Fields

            Constructor

            Public Properties
        }


}

以上是一个Employee对象类:

然后是基于Console程序的文件系统创建和流文件写入的Assistant类:

using System;
using System.Xml;
using System.Text;
using System.IO;
using System.Xml.Serialization;


namespace XMLTextWriter
{
    /// <summary>
    /// XmlWriterAssitant 的摘要说明。
    /// </summary>
    public class XmlWriterAssitant
    {
        public XmlWriterAssitant()
        {
            //
            // TODO: 在此处添加构造函数逻辑
            //
        }
        /// <summary>
        /// 写入日志
        /// </summary>
        /// <param name="xmlFilePath">//@"C:\LogInfo\Log.xml"</param>
        public void WriterXML(string xmlFilePath)
        {
            //创建文件
            CreateFile(xmlFilePath);

            /**************/
            System.Xml.XmlTextWriter xmlWr=new XmlTextWriter(xmlFilePath,Encoding.ASCII);            

            xmlWr.Formatting =Formatting.Indented;

            xmlWr.WriteStartDocument();

            xmlWr.WriteStartElement("profile");
            xmlWr.WriteAttributeString("company","usst");
            xmlWr.WriteStartElement("employee");
            xmlWr.WriteAttributeString("name","worker1");
            xmlWr.WriteAttributeString("age","21");
            xmlWr.WriteStartElement("job");
            xmlWr.WriteAttributeString("title","Team Leader");

            xmlWr.WriteEndElement();

            xmlWr.WriteEndElement();

            xmlWr.WriteEndElement();


            xmlWr.WriteEndDocument();
            

            xmlWr.Flush();

            xmlWr.Close();

            Console.WriteLine("XML写入完成");


            /*******************/

            CreateFile(@"C:\LogInfo\EmployeeInfo.xml");

            EmployeeData emp=new EmployeeData();
            emp.Address="ShangHai";
            emp.Code="001";
            emp.DeptID=1;
            emp.EmployeeID=1;
            emp.Name="John Avent";
            emp.IsDelete=1;
            emp.PassWord="001";
            emp.Phone="021-12345678";
            emp.UserName="User";
            emp.IsLogin=true;

            System.IO.StreamWriter sWriter=new StreamWriter(@"C:\LogInfo\EmployeeInfo.xml");
            //串行化对象
            System.Xml.Serialization.XmlSerializer xmlSer=new XmlSerializer(emp.GetType());

            xmlSer.Serialize(sWriter,emp);

            sWriter.Close();

            /******Read****/

            DeserializeStream(@"C:\LogInfo\EmployeeInfo.xml");

            /**************/

        }
        /// <summary>
        /// 反序列化一个对象
        /// </summary>
        /// <param name="xmlFilePath"></param>
        private void DeserializeStream(string xmlFilePath)
        {
            EmployeeData emp=new EmployeeData();

            System.IO.FileStream fStream=new FileStream(xmlFilePath,FileMode.Open,FileAccess.Read);

            System.Xml.Serialization.XmlSerializer xmlSer=new XmlSerializer(emp.GetType());
            //对读出的XML文件反序列化对象 
            emp=(EmployeeData)xmlSer.Deserialize(fStream);

            Console.WriteLine("Employee's name is :"+emp.Name);
            Console.WriteLine("Employee's phone is:"+emp.Phone);
            Console.WriteLine("Employee's address is:"+emp.Address);

            Console.WriteLine("That's all.");

            fStream.Close();            

        }

        private void CreateFile(string xmlFilePath)
        {
            try
            {
                System.IO.DirectoryInfo dirOne=new DirectoryInfo(@"C:\LogInfo");
                //Directory doesn't exits ,then we create the instance of the directory
                if(!dirOne.Exists)
                {
                    dirOne.Create();
                    dirOne.Refresh();
                    Console.WriteLine("Directory 'C:LogInfo' Create Successd!");
                }
                else
                {
                    //throw new Exception("Cann't Create the Directory!The Directory already exists!");
                }
                System.IO.FileInfo fileOne=new FileInfo(xmlFilePath);

                //File Doesn't exists
                if(!fileOne.Exists)
                {
                    fileOne.Create();
                    fileOne.Refresh();
                    Console.WriteLine("File {0} Create Successd!",xmlFilePath);
                }
                else
                {
                    //throw new Exception("Cann't Create the file!The file already exists!");
                }
            }
            catch
            {

            }
        }
    }
}

然后我们在主输入类调用这部分程序:
using System;
using System.Xml;

using System.Text;
using System.IO;

namespace XMLTextWriter
{
    /// <summary>
    /// MainClass 的摘要说明。
    /// </summary>
    class MainClass
    {
        /// <summary>
        /// 应用程序的主入口点。
        /// </summary>
        [STAThread]
        static void Main(string[] args)
        {
            //
            // TODO: 在此处添加代码以启动应用程序
            //        
            XmlWriterAssitant xwA=new XmlWriterAssitant();
            xwA.WriterXML(@"C:\LogInfo\Log.xml");


            

            /*88*******************/  
            Console.ReadLine();
        }
        
    }
}
