C＃二进制序列化

Question

I am trying to serialize and deserialize objects to/from a Byte array for network communication, I currently have an interface 'ISerialize'. However I got thinking there should be a more robust way to do this via reflection.

I've looked around a little bit at doing this using BinaryFormater, but I can't see if it will give me the control I require.

EDIT:

I would like to beable to decorate a class as Follows (Where fields can be any type so long as they are a system type or are also [Serializable])

[Serializable]
public class MyClass {

    [NonSerialized]
    SomeOtherClass _classFeild;

    [Position (0)]
    UInt16 _field1;

    [Position (14)]
    UInt32 _feild2;

    //..........
}

And have the following functionality,

void Test () {
    MyObject = new MyClass ();
    Byte[] raw;
    raw  =  Serializer.Serialize (MyClass); // Results in _field1 at raw[0,1]
                                            //            _field2 at raw[14-18]

    MyClass Deserialized  = Serializer.Deserialize<MyClass> (raw); 
}

where all fields are swapped to / from network order (bigendian)

---

I would also rather white list fields to be serialized rather than blacklist those not to be. So the question is, is can I do this using the Framework, or do I need to write my own implementation?

Answer 1

听起来非常适合BinaryWriter和BitConverter 。

Answer 2

BinarySerializer将完成所有这些以及更多。

Answer 3

I think the project I recently put on github might be just the fight for you. I claim it will be the fastest binary serializer available and it has zero overhead. Every property is directly represented by its binary value.

Check out: https://github.com/Toxantron/CGbR#binary-datacontract-serializer

Input is right now the DataContract and DataMember attribute

[DataContract]
public partial class Root
{
    [DataMember]
    public int Number { get; set; }

    [DataMember]
    public Partial[] Partials { get; set; }

    [DataMember]
    public IList<ulong> Numbers { get; set; }
}

and the generator output

    public byte[] ToBytes(byte[] bytes, ref int index)
    {
        // Convert Number
        Buffer.BlockCopy(BitConverter.GetBytes(Number), 0, bytes, index, 4);;
        index += 4;
        // Convert Partials
        // Two bytes length information for each dimension
        Buffer.BlockCopy(BitConverter.GetBytes((ushort)(Partials == null ? 0 : Partials.Length)), 0, bytes, index, 2);
        index += 2;
        foreach(var value in Partials ?? Enumerable.Empty<Partial>())
        {
            value.ToBytes(bytes, ref index);
        }
        // Convert Numbers
        // Two bytes length information for each dimension
        Buffer.BlockCopy(BitConverter.GetBytes((ushort)(Numbers == null ? 0 : Numbers.Count)), 0, bytes, index, 2);
        index += 2;
        foreach(var value in Numbers ?? Enumerable.Empty<ulong>())
        {
            Buffer.BlockCopy(BitConverter.GetBytes(value), 0, bytes, index, 8);;
            index += 8;
        }
        return bytes;
    }

Take a look at protobuf-net . It's a great library for doing exactly what you want. It is a third party library, however it does store the data in a well defined format that can be read by other libraries both in C# and numerous other languages.

Here is a sample of how to use it: http://code.google.com/p/protobuf-net/wiki/GettingStarted

I've used it myself and was quite pleased.
