I completed my winform application.
I want to add a csv file. So my application will reach with this path.
How can I get published locastion's path?
I think you mean following with published locations:
Environment.CurrentDirectory
Environment.GetFolderPath(...)
with one of following parameter
SpecialFolder.ApplicationData
SpecialFolder.Desktop
...
etc.
