what is the value of handle in this context?

[catlowlevel]

inside the method class, there's this line inside invokeRaw method

if (this.isInflated) {
    allocatedParameters.push(this.handle);
}

what is handle in here? Is it the MethodInfo*

I am attempting to invoke a method in C++, and it's resulting in crashes. I suspect I need this handle as the method I'm trying to invoke is inflated. Here's how I currently invoke it:

template<typename T, typename... Args>
T MethodInfo::invoke(Il2CppObject *instance, Args &&... args) {
    using Invoker = T(*)(Il2CppObject *, Args...);
    auto invoker = reinterpret_cast<Invoker>(this->methodPointer);
    return invoker(instance, std::forward<Args>(args)...);
}

Yes.

The following C# code

class Class : Interface
{
    static Class()
    {

    }
}

is transpiled to the following C++ code

// System.Void Class::.cctor()
extern "C" IL2CPP_METHOD_ATTR void Class__cctor_m8C31123D4284696F79E3E30569AF75657805F8B7 (const RuntimeMethod* method)
{
    {
        return;
    }
}

More in general, it looks like the method instance is always passed as the last parameter.

However, the compiler eventually removes that parameter if it's unused - but inflated methods actually needs the method instance (for whatever reason I didn't investigate, but it's easy to guess)

I've actually tried passing the MethodInfo* as the last parameter and yet the game is still crashing 🤔

For more context, it is the method get_Item from Dictionary class

Does it occur with every method?

No, it doesn't Only this method so far

Well, I don't really know, then. The method you invoke might be throwing an exception for whatever business logic it implemented as well...

But this module invoked the method just fine, so it couldn't be it

I think you passing the parameters incorrectly, then... I don't know C++ so I can't help you

alright, that's okay. thanks for your time

[catlowlevel]

okay, i was testing stuff and i forgot to change the method name

    auto m = dict->klass->getMethod("get_Item");
    LOGD("is Inflated %d", m->isInflated());
//    int i = 0;
    auto item = dict->invoke_method<Il2CppObject *>("get_Keys", 0, m); //should've been get_Item

now i pass the m directly instead of string literal and now it works
