I have a .NET application which serializes an object in binary format. this object

  • 0

I have a .NET application which serializes an object in binary format.
this object is a struct consisting of a few fields.

I must deserialize and use this object in a C++ application.
I have no idea if there are any serialization libraries for C++, a google search hasn’t turned up much.

What is the quickest way to accomplish this?

Thanks in advance.
Roey.

Update :
I have serialized using Protobuf-net , in my .NET application, with relative ease.
I also get the .proto file that protobuf-net generated, using GetProto() command.
In the .proto file, my GUID fields get a type of “bcl.guid”, but C++ protoc.exe compiler does not know how to interpret them!
What do I do with this?

    If you are using BinaryFormatter, then it will be virtually impossible. Don’t go there…

    Protocol buffers is designed to be portable, cross platform and version-tolerant (so it won’t explode when you add new fields etc). Google provide the C++ version, and there are several C# versions freely available (including my own) – see here for the full list.

    Small, fast, easy.

    Note that the v1 of protobuf-net won’t handle structs directly (you’ll need a DTO class), but v2 (very soon) does have tested struct support.
