OpenFileDialog and Environment.CurrentDirectory

Question

After using the OpenFileDialog for selecting a file the Environment.CurrentDirectory changes to the folder of the file. Is this normal?

From my understanding Environment.CurrentDirectory should always be the application folder.

Answer 1

Have a look at

Difference of AppDomain.CurrentDomain.BaseDirectory and Environment.CurrentDirectory

What is the difference of the follows ?

1. AppDomain.CurrentDomain.BaseDirectory
2. Environment.CurrentDirectory
3. AppDomainSetup.ApplicationBase

1 and 3 are basically thr same. The difference is that AppDomainSetup.ApplicationBase is writable, but AppDomain.BaseDirectory is read-only since you can't change it after the appdomain has been created.

2 is something entirely different. It's used to resolve relative paths, among other things. You can change the CurrentDirectory at any time in your code, and it may also be changed by things like the FileDialogs.
