可能有多個引數的動作引數-有解無憂

我有一個WaitAndRun功能。我希望這種方法非常通用。

public static IEnumerator WaitAndRun<T>(float time, Action<T> action, object arg)
{
    yield return new WaitForSeconds(time);
    action((T)arg);
}

它與以下示例完美配合：

void an_action(int x)
{
    Debug.Log(x);
}
//...
WaitAndRun<int>(1, an_action, 2);

問題是當我還需要多個 args 時，我想使用相同的定義。我怎樣才能讓這個函式支持同時呼叫單個和多個 args？例如：

void another_action(int x, int y);

如果我使用object[] args而不是object arg，我不確定如何修改其余部分。

編輯：將 func 更改為 action

uj5u.com熱心網友回復：

這是一個替代建議：使用 lambda 運算式及其捕獲區域變數的能力：

public static IEnumerator WaitAndRun(float time, Action action)
{
    yield return new WaitForSeconds(time);
    action();
}

用法：

WaitAndRun(1, () => an_action(2));
WaitAndRun(1, () => another_action(2, 3));

    action(arg);

請注意，Action<...>僅定義了 16 個引數。

我也改func到action作為一個函式嚴格回傳一個值，我想非常清楚。
