我把你的类送入CGbR generator的自由。 由于它处于早期阶段,它不支持DateTime
,所以我简单地用它替换了它。生成的序列化的代码如下所示:
public int Size
{
get
{
var size = 24;
// Add size for collections and strings
size += Cts == null ? 0 : Cts.Count * 4;
size += Tes == null ? 0 : Tes.Count * 4;
size += Code == null ? 0 : Code.Length;
size += Message == null ? 0 : Message.Length;
return size;
}
}
public byte[] ToBytes(byte[] bytes, ref int index)
{
if (index + Size > bytes.Length)
throw new ArgumentOutOfRangeException("index", "Object does not fit in array");
// Convert Cts
// Two bytes length information for each dimension
GeneratorByteConverter.Include((ushort)(Cts == null ? 0 : Cts.Count), bytes, ref index);
if (Cts != null)
{
for(var i = 0; i < Cts.Count; i++)
{
var value = Cts[i];
value.ToBytes(bytes, ref index);
}
}
// Convert Tes
// Two bytes length information for each dimension
GeneratorByteConverter.Include((ushort)(Tes == null ? 0 : Tes.Count), bytes, ref index);
if (Tes != null)
{
for(var i = 0; i < Tes.Count; i++)
{
var value = Tes[i];
value.ToBytes(bytes, ref index);
}
}
// Convert Code
GeneratorByteConverter.Include(Code, bytes, ref index);
// Convert Message
GeneratorByteConverter.Include(Message, bytes, ref index);
// Convert StartDate
GeneratorByteConverter.Include(StartDate.ToBinary(), bytes, ref index);
// Convert EndDate
GeneratorByteConverter.Include(EndDate.ToBinary(), bytes, ref index);
return bytes;
}
public Td FromBytes(byte[] bytes, ref int index)
{
// Read Cts
var ctsLength = GeneratorByteConverter.ToUInt16(bytes, ref index);
var tempCts = new List<Ct>(ctsLength);
for (var i = 0; i < ctsLength; i++)
{
var value = new Ct().FromBytes(bytes, ref index);
tempCts.Add(value);
}
Cts = tempCts;
// Read Tes
var tesLength = GeneratorByteConverter.ToUInt16(bytes, ref index);
var tempTes = new List<Te>(tesLength);
for (var i = 0; i < tesLength; i++)
{
var value = new Te().FromBytes(bytes, ref index);
tempTes.Add(value);
}
Tes = tempTes;
// Read Code
Code = GeneratorByteConverter.GetString(bytes, ref index);
// Read Message
Message = GeneratorByteConverter.GetString(bytes, ref index);
// Read StartDate
StartDate = DateTime.FromBinary(GeneratorByteConverter.ToInt64(bytes, ref index));
// Read EndDate
EndDate = DateTime.FromBinary(GeneratorByteConverter.ToInt64(bytes, ref index));
return this;
}
我创造了这样的采样对象的列表:
var objects = new List<Td>();
for (int i = 0; i < 1000; i++)
{
var obj = new Td
{
Message = "Hello my friend",
Code = "Some code that can be put here",
StartDate = DateTime.Now.AddDays(-7),
EndDate = DateTime.Now.AddDays(2),
Cts = new List<Ct>(),
Tes = new List<Te>()
};
for (int j = 0; j < 10; j++)
{
obj.Cts.Add(new Ct { Foo = i * j });
obj.Tes.Add(new Te { Bar = i + j });
}
objects.Add(obj);
}
我的机器上结果Release
编译:
var watch = new Stopwatch();
watch.Start();
var bytes = BinarySerializer.SerializeMany(objects);
watch.Stop();
尺寸: 149000字节
时间: 2.059ms 3.13ms
编辑:与CGbR开始0.4.3二进制序列化支持的DateTime。不幸的是,DateTime.ToBinary
方法非常慢。我会尽快更换它。
EDIT2:当使用UTC DateTime
通过在1.669ms调用ToUniversalTime()
性能被恢复和时钟英寸
性能或代码足迹? – ulrichb 2010-11-10 10:34:56
你问我是否需要性能数据或代码? – aron 2010-11-10 10:41:59
他问的是,“最快的方式”,你的意思是在性能或代码占用方面。 BinaryFormatter在代码和实现方面速度非常快,但像Marc这样的解决方案在基准测试中表现更快。 – 2010-11-10 11:54:44
