Usage instructions

1. The () method in Net Framework is used to obtain the current working directory of the application.

If you use this method to obtain the directory where the application is located, you should note that the directory path obtained by the () method changes with the directory determined by the OpenFileDialog, SaveFileDialog and other objects (switch the working directory).

The value obtained by this method will be changed every time a folder is opened or a file is viewed using Explorer.

2. You can get the directory where the application runs, which does not change with the folder you open.

It is only related to the application running directory, and its value is equal to the root directory where the application is started.

For example, if you install the program and are in the C:\Program Files\Program folder, then it is the value.
