C# Serialization

C# Serialzation

使用 C# 序列化物件

最近常遇到將物件序列化的問題，
想說乾脆將物件序列化的方法寫成一個工具，稱為 SerialzationHelper，
套上泛型就可以適用在所有的物件了。(當然該物件必須是 serializable 的才可以啦)

Book 是用來測試的可序列化類別，
Main 是使用序列化的過程，
SerialzationHelper 是序列化工具。

完整範例：

	[Serializable]
	/// <summary> Book Class </summary>
	internal class Book
	{
	/// <summary> Book Name </summary>
	public string Name { get; set; }
	/// <summary> Book ID </summary>
	public int Id { get; set; }
	/// <summary> Book PublishDate </summary>
	public DateTime PublishDate { get; set; }
	/// <summary> Book RawData </summary>
	public byte[] RawData { get; set; }
	}

	public static void Main(string[] args)
	{
	Book book = new Book();
	book.Name = "Test Book";
	book.Id = 12345;
	book.PublishDate = DateTime.Now;
	book.RawData = new byte[] {1, 2, 3};
	byte[] data = SerialzationHelper.BinarySerialize(book);
	Book book2 = SerialzationHelper.BinaryDeserialize<Book>(data);
	}

	public static byte[] BinarySerialize(object obj)

	IFormatter formatter = new BinaryFormatter();
	using (var stream = new MemoryStream())
	{
	formatter.Serialize(stream, obj);
	data = stream.GetBuffer();
	}
	return data;
	}

	T obj;
	IFormatter formatter = new BinaryFormatter();
	using (var stream = new MemoryStream(data))
	{
	obj = (T)formatter.Deserialize(stream);
	}
	return obj;
	}
	}
