c# - How to get the current file path and know if the file is saved

Question

I'm making a simple text editor in .net. I need to know how to get two things to work:

1. I need to know the full path of the current working file in the editor
2. I need to prompt the user to save the file on exit if it's not already saved (at all)

Please explain on how to get the above implemented. Thanks! :)

Answer 1

查看OpenFileDialog将解释如何从文件系统中选择文件的课程。这是您可以开始的地方。

保存文件很简单，你可以使用System.IO;检查文件是否存在 例如File和FileInfo类开始，然后回到这里进一步的问题，这将是不可避免的。

祝你好运。
