推荐答案

只有从用户那里获取有效路径才需要SaveFileDialog。

当您已经知道路径时，您不需要SaveFileDialog。只需在字符串变量中构造文件名，并使用此路径和Save（）方法。

A SaveFileDialog is only needed to get a valid path from the user.
When you already know the path, you don't need a SaveFileDialog. Just construct the filename in a string variable and use this path with the Save() method.
