序列化 (Serialization)將對象的狀態(tài)信息轉(zhuǎn)換為可以存儲或傳輸?shù)男问降倪^程。在序列化期間，對象將其當(dāng)前狀態(tài)寫入到臨時(shí)或持久性存儲區(qū)。以后，可以通過從存儲區(qū)中讀取或反序列化對象的狀態(tài)，重新創(chuàng)建該對象。（摘自百度百科） 在很多通訊或者數(shù)據(jù)存儲的過程中，都需要序列化和反序列化的過程。 在C#中，如果想要進(jìn)行自定義類的序列化，只需要簡單地在定義類的時(shí)候添加Serializable標(biāo)簽即可。如：
經(jīng)常用到的序列化方式有兩種：二進(jìn)制和XML，分為由System.Runtime.Serialization.Formatters.Binary.BinaryFormatter和System.Xml.Serialization.XmlSerializer實(shí)現(xiàn)。 BinaryFormatter進(jìn)行序列化和反序列化的時(shí)候，不會關(guān)心實(shí)際類型。但是XmlSerializer需要。 自己寫的一個簡單的序列化輔助類  public static class SerializeHelper
{ /// <summary>

stream.Close( ); return data;
} /// <summary>

public static byte[] SerializeToXml(object obj)

XmlSerializer xs = new XmlSerializer(obj.GetType( ));
xs.Serialize(stream , obj); byte[] data = stream.ToArray( );
stream.Close( ); return data;
} /// <summary>
/// 將二進(jìn)制數(shù)據(jù)反序列化 /// </summary>
/// <param name='data'></param>

public static object DeserializeWithBinary(byte[] data)
{
MemoryStream stream = new MemoryStream( );
stream.Write(data , 0 , data.Length);
stream.Position = 0;
BinaryFormatter bf = new BinaryFormatter( ); object obj = bf.Deserialize(stream);
stream.Close( ); return obj;
} /// <summary>

stream.Write(data , 0 , data.Length);
stream.Position = 0;
XmlSerializer xs = new XmlSerializer(typeof(T)); object obj = xs.Deserialize(stream);
stream.Close( ); return (T)obj;
}
} 注意，在反序列化的時(shí)候，將byte[]寫入流以后，需要將游標(biāo)移到首位，即將Position置零，否則反序列化將報(bào)錯。 摘自https://www.cnblogs.com/hualuo-code/p/5165367.html |
