利用扩展方法重写JSON序列化和反序列化

利用.NET 3.5以后的扩展方法重写JSON序列化和反序列化，在代码可读性和可维护性上更加加强了。

首先是不使用扩展方法的写法

定义部分：

1. /// <summary> 
2. /// JSON序列化反序列化工具 
3. /// </summary> 
4. public class JSONControl 
5. { 
6. /// <summary> 
7. /// JSON序列化 
8. /// </summary> 
9. /// <typeparam name="T"></typeparam> 
10. /// <param name="_Object"></param> 
11. /// <returns></returns> 
12. public static String JsonSerializer<T>(T _Object) 
13. { 
14. using (MemoryStream TempMemoryStream = new MemoryStream()) 
15. { 
16. String MySerializationString = String.Empty; 
17. DataContractJsonSerializer MyDataContractJsonSerializer = new DataContractJsonSerializer(typeof(T)); 
18. MyDataContractJsonSerializer.WriteObject(TempMemoryStream, _Object); 
19. MySerializationString = Encoding.UTF8.GetString(TempMemoryStream.ToArray()); 
20. return MySerializationString; 
21. } 
23. } 
25. /// <summary> 
26. /// 反序列化 
27. /// </summary> 
28. /// <typeparam name="T"></typeparam> 
29. /// <param name="_JsonString"></param> 
30. /// <returns></returns> 
31. public static T JsonDeserializer<T>(String _JsonString) 
32. { 
33. using (MemoryStream TempMemoryStream = new MemoryStream(Encoding.UTF8.GetBytes(_JsonString))) 
34. { 
35. DataContractJsonSerializer MyDataContractJsonSerializer = new DataContractJsonSerializer(typeof(T)); 
36. return (T)MyDataContractJsonSerializer.ReadObject(TempMemoryStream); 
37. } 
38. } 
39. }

使用部分：

1. /// <summary> 
2. /// 场景控制对象 
3. /// </summary> 
4. public class SceneControl 
5. { 
6. /// <summary> 
7. /// 临时序列化对象 
8. /// </summary> 
9. [DataContract] 
10. public class TempClass 
11. { 
12. /// <summary> 
13. /// 属性1 
14. /// </summary> 
15. [DataMember(Name = "Property1")] 
16. public String Property1 { get; set; } 
18. /// <summary> 
19. /// 属性2 
20. /// </summary> 
21. [DataMember(Name = "Property2")] 
22. public String Property2 { get; set; } 
23. } 
25. /// <summary> 
26. /// 测试 
27. /// </summary> 
28. public void Test() 
29. { 
30. String JsonString = "{'Property1':'111','Property2':'2'}"; 
31. TempClass MyTempClass = JSONControl.JsonDeserializer<TempClass>(JsonString); 
32. } 
33. }

然后是使用扩展方法的写法

定义部分：

1. /// <summary> 
2. /// JSON序列化反序列化工具 
3. /// </summary> 
4. public static class JSONControl 
5. { 
6. /// <summary> 
7. /// JSON序列化 
8. /// </summary> 
9. /// <typeparam name="T"></typeparam> 
10. /// <param name="_Object"></param> 
11. /// <returns></returns> 
12. public static String ObjectToJson<T>(this T _Object) 
13. { 
14. using (MemoryStream TempMemoryStream = new MemoryStream()) 
15. { 
16. String MySerializationString = String.Empty; 
17. DataContractJsonSerializer MyDataContractJsonSerializer = new DataContractJsonSerializer(typeof(T)); 
18. MyDataContractJsonSerializer.WriteObject(TempMemoryStream, _Object); 
19. MySerializationString = Encoding.UTF8.GetString(TempMemoryStream.ToArray()); 
20. return MySerializationString; 
21. } 
23. } 
25. /// <summary> 
26. /// JSON反序列化 
27. /// </summary> 
28. /// <typeparam name="T"></typeparam> 
29. /// <param name="_JsonString"></param> 
30. /// <returns></returns> 
31. public static T JsonToObject<T>(this String _JsonString) 
32. { 
33. using (MemoryStream TempMemoryStream = new MemoryStream(Encoding.UTF8.GetBytes(_JsonString))) 
34. { 
35. DataContractJsonSerializer MyDataContractJsonSerializer = new DataContractJsonSerializer(typeof(T)); 
36. return (T)MyDataContractJsonSerializer.ReadObject(TempMemoryStream); 
37. } 
38. } 
39. }

使用部分：

1. /// <summary> 
2. /// 场景控制对象 
3. /// </summary> 
4. public class SceneControl 
5. { 
6. /// <summary> 
7. /// 临时序列化对象 
8. /// </summary> 
9. [DataContract] 
10. public class TempClass 
11. { 
12. /// <summary> 
13. /// 属性1 
14. /// </summary> 
15. [DataMember(Name = "Property1")] 
16. public String Property1 { get; set; } 
18. /// <summary> 
19. /// 属性2 
20. /// </summary> 
21. [DataMember(Name = "Property2")] 
22. public String Property2 { get; set; } 
23. } 
25. /// <summary> 
26. /// 测试 
27. /// </summary> 
28. public void Test() 
29. { 
30. String JsonString = "{'Property1':'111','Property2':'2'}"; 
31. TempClass MyTempClass = JsonString.JsonToObject<TempClass>(); 
32. } 
33. }
