Question

I have the following code in an Winform Application

 String[] lines = { "LAST MESSAGE", "101" };
 File.WriteAllLines("MPP_Config.txt", lines);

On my Development system, the file gets created under Bin\Debug…

Where will the file be created in the client once it is installed in the client system ?

I deploy to a website using Click once Deployment…

I believe it will be created in current working directory of the application. The application might not have access to this directory, especially on systems with UAC, Vista and windows 7. You should probably think about using the application data directory instead.

String[] lines = { "LAST MESSAGE", "101" };
String fileName = Path.combine(System.Deployment.Application.ApplicationDeployment.CurrentDeployment.DataDirectory,"MPP_Config.txt");
File.WriteAllLines(fileName, lines);
