I've done quite a bit of searching and couldn't find the answer to this question. I have a set of C++ structures that are serialized to a file using simple fwrite(). There is no formatting, just a dump of the memory into a file from an existing C++ application. I am now writing a C# application that must load the data from the files back into C++ structures and do some operations on the fields. I am successfully using SWIG to generate proxy classes, however I'm not sure how to go about the serialization. Ideally I'd just be able to copy data I read from the file into the C++ structures' memory. I am not sure how to do this from C# since the proxy classes don't expose the underlying memory model. I also don't like the idea of inlining my own code into the interface file as I have hundreds of structures and I specifically chose SWIG because it can generate proxy code without me having to specify the interface manually. Does SWIG offer any functionality that may help me solve this problem?
