WinForm Traps for relative paths

This article describes traps that you need to be aware of when using WinForm relative paths. This type of error is often encountered! The present analysis is as follows for everyone's reference.

When working with relative paths on the window system, there is a "

Current directory

"Concept,

If the program is using a relative path to operate, the system will be considered to be in the current directory operation, that is, the relative path is equal to the current directory + relative path composed of absolute path

。

The default current directory for the application is:

Path of the program entry

。

And in the WinForm,

Openfiledialog.restoredirectory or Savefiledialog.savefiledialog settings can affect the current directory, which can cause changes to the current directory

。

Once the current directory changes, it will affect the relative path, resulting in incorrect addressing of the file system

。

So in the actual programming, please use the relative path with caution! If a bug occurs because of a relative path, it will make you feel like crying without tears!

I hope this article will be helpful to you in C # program design.
