C#序列化问题

一、本章主要介绍.NET xml序列化，构建XML序列化的框架类，主要放在你的框架项目里面，类名字命名为Serialiser，我的框架项目名称是MingXu.FrameWork，我将Serialiser放到它下面，MingXu.FrameWork类型为Class Library

 

二、序列化类用到了2个dll，分别为：

     System.Xml.Serialization：XML序列化类

     System.IO：IO类

注意添加对System.Xml.Serialization及System.IO的引用。

如果不知道怎么添加对dll的引用，请参见微软 MSMQ 使用 第二章 构造MSMQ的框架类

 

三、代码如下：代码都有注释，所以不做过多的解释了，如果有看不明白的，请在评论里面留言，我在加注释

using System.Text;

using System.Xml.Serialization;

using System.IO;

using System.Diagnostics;

 

 

namespace MingXu.FrameWork

{

    /// <summary>

        public static void Serialize(T obj, string filepath)

        {

            if (string.IsNullOrEmpty(filepath) || obj==null)

                return;

 

            StreamWriter myWriter = null;

            try

            {

                XmlSerializer mySerializer = new XmlSerializer(obj.GetType());

                myWriter = new StreamWriter(filepath);

                mySerializer.Serialize(myWriter, obj);

            }

            catch (Exception ex)

            {

                //Log.Debug(ex.Message);

            }

            finally

            {

                if (myWriter != null)

                {

                    myWriter.Close();

                    myWriter.Dispose();

                    myWriter = null;

                }

            }

 

        }

        public static T Deserialize(string filepath)

        {          

 

            T myObj = default(T);

 

            if (string.IsNullOrEmpty(filepath) || !File.Exists(filepath))

                return myObj;

 

            FileStream myFileStream = null;

            try

            {

                XmlSerializer mySerializer = new XmlSerializer(typeof(T));

                myFileStream = new FileStream(filepath, FileMode.Open);

                myObj = (T)mySerializer.Deserialize(myFileStream);

            }

            catch (Exception ex)

            {

                //Log.Debug(ex.Message);

            }

            finally

            {

                if (myFileStream != null)

                {

                    myFileStream.Close();

                    myFileStream.Dispose();

                    myFileStream = null;

                }

            }

            return myObj;

        }

    }

}

 

 

三、序列化类的使用

1、首先新建一个控制台项目MingXu.ConsoleApp，注意添加对框架类的引用，然后构造一个测试类，用来进行序列化操作，代码如下：

 

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Xml;

using System.Xml.Serialization;

 

namespace MingXu.ConsoleApp

{

    public class xmlSerializationTest

    {

        string _availableVersion;

 

        [XmlElement("availableVersion")]

        public string AvailableVersion

        {

            get { return _availableVersion; }

            set { _availableVersion = value; }

        }

    }

}

 

2、然后在Main函数里添加代码进行操作：

代码如下：

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using Mingxu.TestClass;

using MingXu.FrameWork;

 

namespace MingXu.ConsoleApp

{

    class PRogram

    {

        static void Main(string[] args)

        {

            ser();

            deser();

        }

 

        /// <summary>

        /// 序列化

        /// </summary>

        private static void ser()

        {

            xmlSerializationTest test = new xmlSerializationTest();

            test.AvailableVersion = "Hello world!";

            string path = "d:\\xmlSerializationTest.xml";

            Serialiser<xmlSerializationTest>.Serialize(test, path);

        }

 

        /// <summary>

        /// 反序列化

        /// </summary>

        private static void deser()

        {

            string path = "d:\\xmlSerializationTest.xml";

            xmlSerializationTest test = Serialiser<xmlSerializationTest>.Deserialize(path);

            Console.WriteLine(test.AvailableVersion);

            string bb = Console.ReadLine();

        }

      

    }
