Im calling a function which needs to check if its NOT inside Scene tree IsInsideTree then call self _Ready() method.

E.g. you would do this in Gdscript:

func some_function(text: String) -> void:
    bbcode_text = text
    if not is_inside_tree():
        yield(self, "ready")

What would be equivalent of the above code in C# (csharp)
