If you're wondering how Mono knows what the size of the data array that we pass is, it's simply because it expects the total size of that array to equal the size of *all* the parameters in the C# method, meaning if the array size doesn't match the parameter count you will end up with problems, and Mono *may* not tell you about it.

And that's the basics of how we can retrieve and invoke C# methods from C++! I will obviously go into more depth about parameter types and how we can convert between C++ types and C# types later on.
