How to use (C #) to implement global signals in GDScript

Question

I have encountered some problems: in GDScript, it is easy to link the signal of B in A(A.abc.connect(b)), but I am using C #. How can I implement this function. I reported an error in the code below
`public partial class GameEvents : Node
{

[Signal]
public delegate void GameEventsExpManagerEventHandler(float number); 

public override void _Ready()
{
	this.GameEventsExpManager += EmitExperivalCollected;
}


public void EmitExperivalCollected(float number){
	GD.Print("do something...");
}}`

`public partial class ExperienceVial : Node2D
{
private void OnAreaEntered(Area2D area2D){
EmitSignal(GameEvents.SignalName.GameEventsExpManager,1.0f);
this.QueueFree();
}

public override void _Ready()
{
	GetNode<Area2D>("Area2D").AreaEntered += OnAreaEntered;
}

}
`

Is using event delegation? How should I use C # event delegation to complete?

Answer 1

EmitSignal(GameEvents.SignalName.GameEventsExpManager,1.0f);

This should EmitSignal on the class or instance that defines the signal, e.g. GameEvents.EmitSignal(/* ... */);.

Answer 2

If you directly use (GameEvents. SignalName. GameEventsExpManager), it will show that the signal is undefined.What I want is A to define signal a, and B to connect signal a to trigger its own method b. However, thank you all the same. I have already completed this function
