Writing to File in C# with/without relative paths

I am currently trying to get user input from commandline OutputPath

 using (outfile = new StreamWriter(OutputPath))
 {
     outfile.Write(result);
 }

This writes to absolute path if given or writes the file under c:\windows\system32

How can I make it either absolute path or depending on the current directory. Is there a way to get the current working directory from command line or is there a better API that can figure it out.

Thanks

Use Path.IsPathRooted to figure out whether the input is absolute or not, and Environment.CurrentDirectory to get the current Directory. With this information you should be all set.

C# does know how to use relative paths based on the current directory.

If you're seeing files created in C:\Windows\System32, then probably that IS your current working directory.

A shortcut can set the working directory of the program it is launching. Open/Save common file dialogs also mess with the current working directory.

If you launch an application without using a shortcut, it will inherit the current directory from the parent process. explorer.exe usually has C:\Windows\System32 as the working directory, which make it pretty common for applications launched by double-clicking an icon in Explorer.

You can use Directory.GetCurrentDirectory to get the current working directory on OS.
