所以msgpack-c为我提供了objects as arrays。说我像这样序列化了一条C ++消息:
template <class T>
struct Message {
std::vector<T> data;
std::vector<int> shape;
MSGPACK_DEFINE(data, shape);
};
并拥有T == double
。
如果在C ++中反序列化为json,它将具有[[1.23,3.01,44.02,33],[2,2]]
之类的内部内容。
现在,我想在C# with MessagePack-CSharp中反序列化它。如果我尝试将其转换为json字符串,当我尝试
时会得到一个空字符串var msg = MessagePackSerializer.Deserialize<List<List<double>>>(e.RawData);
我知道
System.InvalidOperationException:代码无效。代码:0 格式:正fixint位于 MessagePack.Decoders.InvalidArrayHeader.Read(System.Byte []个字节, Int32偏移量,System.Int32&readSize)[0x0001b]在 MessagePack / MessagePackBinary.cs:3543
当我尝试时会发生同样的事情:
[MessagePackObject]
public class Msg {
[Key(0)]
public List<double> data;
[Key(1)]
public List<int> shape;
}
那么如何在C#MessagePack-CSharp中反序列化[[doubles], [ints]]
数组?
答案 0 :(得分:0)
[MessagePackObject]
public class Msg
{
[Key(0)]
public List<double> data;
[Key(1)]
public List<int> shape;
}
static class Program
{
static void Main(string[] args)
{
var bytes = MessagePackSerializer.Serialize(new Msg()
{
data = new List<double> { 1.23, 3.01, 44.02, 33 },
shape = new List<int>() { 2, 2 }
});
var msg = MessagePackSerializer.Deserialize<Msg>(bytes);
Console.WriteLine(MessagePackSerializer.ToJson(msg));
}
}
应该完成工作并产生输出[[1.23,3.01,44.02,33],[2,2]]
