C#学习——序列化和反序列化练习的重构

目的：

代码的重构！我上一次写的随笔“C#学习——序列化和反序列化”对接口的理解似乎有误，接口基本上没进行什么设计，之后虽然也重新设计了一下，

但是写了两个接口IDeserialize和ISerialize每个接口里面只有一方法，分别为反序列化和序列化，有点感觉过度设计，所以现在写了一篇

C#学习——序列化和反序列化练习的重构，来改正这一错误，这一例子觉得有一些地方写的不妥，希望大家觉得哪里不顺眼，踊跃发言哈！

示例：

1、新建解决方案Serializer

2、新建类库Jack.Gao.Domain，并在该类库下添加Person类，Person类的代码如下：

View Code

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 using System.Runtime.Serialization.Formatters;
 6 
 7 namespace Jack.Gao.Domain
 8 {
 9     [Serializable]
10     public class Person
11     {
12         //如果不想实例化某一个字段，可以使用特性NonSerialized标记
13         private int _id;
14         public int Id
15         {
16             get { return _id; }
17             set { _id = value; }
18         }
19 
20         private string _name;
21         public string Name
22         {
23             get { return _name; }
24             set { _name = value; }
25         }
26 
27         private string _sex;
28         public string Sex
29         {
30             get { return _sex; }
31             set { _sex = value; }
32         }
33     }
34 }

3、新建类库Jack.Gao.PersonFactory，在该库下新建Factory类，用于生成Person。代码如下：

View Code

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 
 6 using Jack.Gao.Domain;
 7 
 8 namespace Jack.Gao.PersonFactory
 9 {
10     public class Factory
11     {
12         #region Create Person
13         public static Person CreatePerson()
14         {
15             return new Person();
16         }
17         #endregion       
18     }
19 }

添加枚举类型SerializerType，代码如下：

View Code

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 
 6 namespace Jack.Gao.PersonFactory
 7 {
 8     public enum SerializerType
 9     {
10         Xml,
11         Binary,
12         Soap
13     }
14 }

再新建一个类SerializerTypeFactory，用于根据类型生成某一特点的序列化方式。不过这里写的代码感觉不想面向对象的，写的有点烂。添加如下代码：

View Code

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 using System.IO;
 6 using System.Runtime.Serialization.Formatters.Binary;
 7 using System.Xml.Serialization;
 8 using System.Diagnostics;
 9 using System.Runtime.Serialization.Formatters.Soap;
10 using Jack.Gao.Domain;
11 
12 namespace Jack.Gao.PersonFactory
13 {
14     public static class SerializerTypeFactory
15     {
16         public static object CreateSerializerType(SerializerType serializerType)
17         {
18             object serializer=null;
19 
20             switch (serializerType)
21             {
22                 case SerializerType.Xml:
23                      serializer = new XmlSerializer(typeof(Person));
24                      break;
25                 case SerializerType.Binary:
26                      serializer = new BinaryFormatter();
27                      break;
28                 case SerializerType.Soap:
29                      serializer = new SoapFormatter();
30                      break;
31                 default:
32                     throw new Exception("Type is not correctly!");
33             }
34 
35             return serializer;
36         }
37     }
38 }

4、新建类库Jack.Gao.Persistence，新建

ISerialize接口、SerializeBase抽象类、BinarySerializePerson、SoapSerializePerson、XmlSerializePerson这三个类分别实现了ISerialize接口。代码如下：

SerializeBase：

View Code

 1 using System.IO;
 2 using Jack.Gao.Domain;
 3 using Jack.Gao.PersonFactory;
 4 
 5 namespace Jack.Gao.Persistence.Base
 6 {
 7     public abstract class SerializeBase
 8     {
 9         protected Person PersonBase { get; set; }
10 
11         protected virtual FileStream FileStreamBase { get; set; }
12 
13         public SerializeBase()
14         {
15             PersonBase = Factory.CreatePerson();
16         }
17 
18         //public virtual void SerializePerson()
19         //{
20             
21         //}
22 
23         //public virtual Person DeSerializePerson()
24         //{
25         //    return new Person();
26         //}
27     }
28 }

11     {
12         public void SerializePerson()
13         {
14             PersonBase.Id = 2;
15             PersonBase.Name = "Jim";
16             PersonBase.Sex = "Man";

18             using (FileStreamBase = new FileStream("Person.txt", FileMode.Create))
19             {
20                 BinaryFormatter binaryFormatter = (BinaryFormatter)SerializerTypeFactory.CreateSerializerType
21                     (SerializerType.Binary);
22                 binaryFormatter.Serialize(FileStreamBase, PersonBase);
23             }
24         }
25 
26         public Person DeSerializePerson()
27         {

35             return PersonBase;
36         }
37     }
38 }

 8 namespace Jack.Gao.Persistence.Implement
 9 {
10     public class SoapSerializePerson : SerializeBase,ISerialize
11     {
12         public void SerializePerson()
13         {
14             PersonBase.Id = 3;
15             PersonBase.Name = "Green";
16             PersonBase.Sex = "Woman";
17 
18             using (FileStreamBase = new FileStream("Person.xml", FileMode.Create))
19             {
20                 SoapFormatter soapFormatter = (SoapFormatter)SerializerTypeFactory.
21                     CreateSerializerType(SerializerType.Soap);
22                 soapFormatter.Serialize(FileStreamBase, PersonBase);
23             }
24         }
25 
26         public Person DeSerializePerson()
27         {
28             using (FileStreamBase = new FileStream("Person.xml", FileMode.Open))
29             {
30                 SoapFormatter soapFormatter = (SoapFormatter)SerializerTypeFactory.
31                     CreateSerializerType(SerializerType.Soap);
32                 PersonBase = (Person)soapFormatter.Deserialize(FileStreamBase);
33             }
34 
35             return PersonBase;
36         }
37     }
38 }

XmlSerializePerson：

View Code

 1 using System.IO;
 2 using System.Xml.Serialization;
 3 using Jack.Gao.Domain;
 4 using Jack.Gao.Persistence.Base;
 5 using Jack.Gao.Persistence.Interface;
 6 using Jack.Gao.PersonFactory;
 7 
 8 namespace Jack.Gao.Persistence.Implement
 9 {
10     public class XmlSerializePerson : SerializeBase,ISerialize
11     {
12         public void SerializePerson()
13         {
14             using (FileStreamBase= new FileStream("Person.xml", FileMode.Create))
15             {
16                 PersonBase.Id = 1;
17                 PersonBase.Name = "Jack Gao";
18                 PersonBase.Sex = "Man";

20                 XmlSerializer xmlSerializer = (XmlSerializer)SerializerTypeFactory.
21                     CreateSerializerType(SerializerType.Xml);
22                 xmlSerializer.Serialize(FileStreamBase, PersonBase);

34 
35             return PersonBase;
36         }
37     }

5、新建控制台输出程序Jack.Gao.AppSerializer，在Program.cs添加如下代码：

View Code

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 using System.IO;
 6 using System.Diagnostics;
 7 
 8 using Jack.Gao.Domain;
 9 using Jack.Gao.Persistence;
10 using Jack.Gao.Persistence.Implement;
11 
12 namespace Jack.Gao.AppSerializer
13 {
14     class Program
15     {
16         private static Person _person=null;
17 
18         static void Main(string[] args)
19         {
20             //XmlSerializePerson xmlSerializePerson = new XmlSerializePerson();
21             //xmlSerializePerson.SerializePerson();
22             //ShowIsSuccess();
23 
24             //_person = xmlSerializePerson.DeSerializePerson();
25             //Console.WriteLine(_person.Id);
26             //Console.WriteLine(_person.Name);
27             //Console.WriteLine(_person.Sex);
28 
29             BinarySerializePerson binarySerializePerson = new BinarySerializePerson();
30             binarySerializePerson.SerializePerson();
31             ShowIsSuccess();
32 
33             _person = binarySerializePerson.DeSerializePerson();
34             Console.WriteLine(_person.Id);
35             Console.WriteLine(_person.Name);
36             Console.WriteLine(_person.Sex);
37 
38             //SoapSerializePerson soapSerializePerson = new SoapSerializePerson();
39             //soapSerializePerson.SerializePerson();
40             //ShowIsSuccess();
41 
42             //_person = soapSerializePerson.DeSerializePerson();
43             //Console.WriteLine(_person.Id);
44             //Console.WriteLine(_person.Name);
45             //Console.WriteLine(_person.Sex);
46 
47             Console.ReadKey();
48         }
49 
50         private static void ShowIsSuccess()
51         {
52             if (IsExitFile())
53             {
54                 Console.WriteLine("Create File sucessfull.");
55             }
56             else
57             {
58                 Console.WriteLine("Create File error.");
59             }
60         }
61 
62         private static bool IsExitFile()
63         {
64             bool exitXmlFile = false;
65 
66             string currentApplicationPath = Process.GetCurrentProcess().MainModule.FileName;
67 
68             if (!string.IsNullOrEmpty(currentApplicationPath))
69             {
70                 exitXmlFile = true;
71             }
72 
73             return exitXmlFile;
74         }
75     }
76 }

运行该程序，可以看到在输出目录下多了一个Person.xml的文件，可以查看里面的内容，以下内容使用soap序列化后生成的，你也可以查看其它的两种方式生成的内容。
