Is there any way to access data of list generics ?

[IceBear1226]

static Game.Tool.Http.HttpObject GetMailReward(System.String[] pMailIds, Game.Tool.Http.HttpResponseEvent<System.Collections.Generic.List<Game.Mail.Data.MailRewardObject>> onComplete); // 0x04664564

I tried to hook on the method above, and get access to every Game.Mail.Data.MailRewardObject in the List, which is the generic type of HttpResponseEvent .

If I use new IL2CPP.Object(arg[1]) , it is a HttpResponseEvent instance. Right?
But in the HttpResponseEvent, it seems there is no field that saves info of the list as generic.

Is it impossible to get access to every MailRewardObject in the generic list of the parameter??

below is the structure of the HttpResponseEvent.

 class Game.Tool.Http.HttpResponseEvent<TResponse> : System.MulticastDelegate
{
    
    System.Void .ctor(System.Object object, System.IntPtr method);
    System.Void Invoke(TResponse response, System.String errorMsg, System.Int32 errorCode); // 0x026b1614
    System.IAsyncResult BeginInvoke(TResponse response, System.String errorMsg, System.Int32 errorCode, System.AsyncCallback callback, System.Object object); // 0x026b1614
    System.Void EndInvoke(System.IAsyncResult result); // 0x0243d148
}

I tried to follow the Generics handling tab, but I have no clue how to move on from the below to get the list elements

	onEnter:function(args){
		
		const mailRuntimeLib = Il2Cpp.domain.assembly("GameMailRuntimeLib")

		const mailRuntimeLibImage = mailRuntimeLib .image;

		const genericList = Il2Cpp.corlib.class("System.Collections.Generic.List`1");

		const mailRewardObject = mailRuntimeLib Image.class("Game.Mail.Data.MailRewardObject");	

		const specificList = genericList.inflate(mailRewardObject);

I almost got to there, but one problem was, invoke() from il2cpp bridge method returns IL2CPP.Method.ReturnType.

How should I read the value from IL2CPP.Method.ReturnType?? I tried to search for it, but there was no progress.

would anyone know it?

The value returned by invoke is indeed the actual value (e.g. you can console.log it) - Il2Cpp.Method.ReturnType is just an union of all the possible types a method invocation can return (e.g. void, number, Il2Cpp.Object...).

Il2Cpp.Method takes a generic type argument, so that you can specify the return type of that method, e.g:

const method = object.method<Il2Cpp.Object>("foo");
const value = method.invoke(); // value is Il2Cpp.Object
