如何获取作为所述函数内的引用类型参数的原始变量的名称?

在下面的例子中,我希望得到输出“rigsBeingPhasedIn”,而不是“rigdiction”(本地引用变量的名称)。

    private static Dictionary<Rig, Coroutine> rigsBeingPhasedIn = new Dictionary<Rig, Coroutine>();

    // the below static method is called by a public facing method
    private static void StopRigBeingPhased(Rig rig, ref Dictionary<Rig, Coroutine> rigDictionary)
    {
        Debug.Log($"{nameof(rigDictionary)}"); // outputs "rigDictionary"
    }

    public static void PhaseRigOut(Rig rig, float duration, float targetWeight) {
        // ...
        StopRigBehingPhased(rig, ref rigsBeingPhasedIn);
        // ...
    }

谢谢你的时间!
