C#: Connecting signal does not work when passing a Dictionary through the binds Array, however it works when passing the Dictionary with something else inside the Array

Godot version:

3.3.2.stable Mono

OS/device including version:

OS: Windows 10 GPU: Nvidia GTX 1050 Ti Backend: OpenGL ES 3

Issue description:

Getting the error: emit_signal: Error calling method from signal 'ready': 'Node(Node.cs)::OnReady': Method not found.. mono_object_to_variant_impl: Attempted to convert an unmarshallable managed type to Variant. Name: 'KeyValuePair`2' Encoding: 21.

when trying to connect the "ready" signal and passing a Dictionary though the Array binds like this: Connect("ready", this, "OnReady", new Array(this.dict)); connecting to: void OnReady(Dictionary<string, int> newDict)

however it works when passing something else inside the array: Connect("ready", this, "OnReady", new Array(42, this.dict)); connecting to: void OnReady(int i, Dictionary<string, int> newDict) like this I still can use the dictionary, but I think it should be possible to use only the Dictionary inside the Array

Steps to reproduce:

Create a Dictionary, and an appropriate method to respond Connect the signal to the method and pass the dictonary though the binds Array

It has nothing to do with the signals. You're just invoking Array(IEnumerable) constructor instead of Array(params object[]). It happens because Dictionary<TKey, TValue> implements IEnumerable.

var emptyDict = new Dictionary<string, int>();
var nonEmptyDict = new Dictionary<string, int>() { { "one", 1 } };

// both invoke Array(IEnumerable) constructor:
new Array(emptyDict); // no error
new Array(nonEmptyDict); // error, can't convert KeyValuePair into Variant

// both invoke Array(params object[]) constructor:
new Array((object)emptyDict); // no error
new Array((object)nonEmptyDict); // no error

@Chaosus Not a bug.
