（C＃的新手）
我有一个已构建的应用程序，可以将文件和文件夹从一个位置复制到另一个位置。我最初遇到文件夹问题。由于某种原因，它将尝试在不创建目录的情况下复制文件。我通过添加第二部分来检查文件夹是否存在以及是否创建该文件夹，从而解决了该问题。我确信有更好的方法来解决此问题，但这是行得通的，所以我同意了。最终目标是这样。
下面是我到目前为止所拥有的，除了上面＃3中描述的内容，它可以执行所有操作。关于如何将功能3中的功能添加到功能中，或简化文件副本并创建文件夹（如果不存在）的任何想法，将不胜感激。

（（C＃的新手）我已经构建了一个应用程序，可以将文件和文件夹从一个位置复制到另一个位置。我最初遇到文件夹问题。由于某些原因，它将尝试复制文件...
您可以用相同的方法来做，也许是这样：
