序列化(Serialize)、反序列化(Deserialize)

.NET框架常用的三种序列化的方式：1、是使用IFormatter进行序列化:使用BinaryFormatter(二进制格式)、SoapFormatter(XML格式)；2、使用XmlSerializer进行序列化(XML格式)，比SoapFormatter的XML格式要简化(去掉了SOAP特有的额外信息)。3、使用DataContractJsonSerializer实现Json格式的序列化和反序列化。

1、使用BinaryFormatter进行串行化

View Code

 1         public string Serialize<T>(T message, IFormatter formatter)
 2         {
 3             //IFormatter formatter = new BinaryFormatter();
 4             //IFormatter formatter = new SoapFormatter();
 5             using (MemoryStream stream = new MemoryStream())
 6             {
 7                 formatter.Serialize(stream, message);
 8                 stream.Position = 0;
 9                 using (StreamReader reader = new StreamReader(stream, Encoding.UTF8))
10                 {
11                     string EncryptMessage = reader.ReadToEnd();
12                     return EncryptMessage;
13                 }
14             }
15         }
16         public T Deserialize<T>(string encryptMessage, IFormatter formatter)
17         {
18             //IFormatter formatter = new BinaryFormatter();
19             //IFormatter formatter = new SoapFormatter();
20             byte[] buff = Encoding.UTF8.GetBytes(encryptMessage);
21             using (MemoryStream stream = new MemoryStream(buff, 0, buff.Length))
22             {
23                 T obj = (T)formatter.Deserialize(stream);
24                 return obj;
25             }
26         }

2、使用XmlSerializer进行串行化

    可以使用[Serializable]属性将类标志为可序列化的。如果某个类的元素不想被序列化，1、可以使用[NonSerialized]属性来标志，2、可以使用[XmlIgnore]来标志。

View Code

 1         public string XmlSerialize<T>(T message)
 2         {
 3             XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));
 4             using (MemoryStream stream = new MemoryStream())
 5             {
 6                 xmlSerializer.Serialize(stream, message);
 7                 stream.Position = 0;
 8                 using (StreamReader reader = new StreamReader(stream, Encoding.UTF8))
 9                 {
10                     string res = reader.ReadToEnd();
11                     return res;
12                 }
13             }
14         }
15         public T XmlDeserialize<T>(string encryptMessage)
16         {
17             XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));
18             byte[] buff = Encoding.UTF8.GetBytes(encryptMessage);
19             using (MemoryStream stream = new MemoryStream(buff, 0, buff.Length))
20             {
21                 T obj = xmlSerializer.Deserialize(stream);
22                 return obj;
23             }
24         }

3、使用DataContractJsonSerializer实现Json格式的序列化和反序列化

注意：必须使用DataContractAttribute对类进行标记，使用DataMemberAttribute类成员进行标记，否则该类无法被序列化。

View Code

 1         public string JsonSerialize<T>(T message)
 2         {
 3             DataContractJsonSerializer json = new DataContractJsonSerializer(typeof(T));
 4             using (MemoryStream stream = new MemoryStream())
 5             {
 6                 json.WriteObject(stream, message);
 7                 stream.Position = 0; 
 8                 using (StreamReader reader = new StreamReader(stream, Encoding.UTF8)) 
 9                 {
10                     string res = reader.ReadToEnd();
11                     return res;
12                 }
13             }
14         }
15         public T JsonDeserialize<T>(string message)
16         {
17             DataContractJsonSerializer json = new DataContractJsonSerializer(typeof(T));
18             using (MemoryStream stream = new MemoryStream())
19             {
20                 T obj = (T)json.ReadObject(stream);
21                 return obj;
22             }
23         }

注：.NET Framework 3.5下才可用DataContractJsonSerializer！
