FIle path in app.config

Hi,

I always have doubt regarding how a path is formed whenever we run a windows app.

I have set a key like this in my app config

C#

<add key="LogFilePath" value="..\Log\" />

When i run this from my local machine, it provides the path from where the windows app is run.

But when i run the same project from TFS, and when i try to create a file inside the Log folder , instead of the project mapped path it gives an entirely different path.

Can anyone tell me why this happens?

Note that a log file must not be placed in the program folder: a non-administrative user does not have sufficient priviledges to write it. Use e.g. %appdata%. That can be expanded by the Environment class.

XML

<add key="LogFilePath" value="%appdata%\YourCompany\Logs\xy.log" />

C#

string val = ConfigurationManager.AppSettings["LogFilePath"];
string path = System.Environment.ExpandEnvironmentVariables(val);

I suggest you determine the relevant run-time directory-paths in code:

C#

string appStartUp = Application.StartupPath;

string currentDirectory = Environment.CurrentDirectory;

string desktop = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);

Other useful information for global system paths can be found in the Environment.SpecialFolder Enumeration: [^].

what about this
string filePath = Directory.GetParent(Path.GetDirectoryName(Application.StartupPath)) + ConfigurationManager.AppSettings["LogFilePath"];
