c# - 如何从我的日历中删除所有面板？

Question

我现在正在使用 C# 编写日历。如果我调用我的日历，它会创建与当月有天数一样多的面板。但是，如果我想将当前月份增加一个，则当前月份的面板会停在那里。所以我必须在更改月份后立即删除所有面板。但是在这种情况下我该怎么做呢？

感谢您的帮助。

代码说明:首先，我调用 createPanel 方法，为当月创建面板。接下来，如果我单击 MonthAdd 方法，我想删除我创建的所有面板。

       ...
        for (int i = 0; i <= numDays; i++)
        {
                //Create Panel
                test[i] = new Panel(); 
        }

        ...

然后

            this.Control.Remove(test[i]);
