If you assume the Visual Studio directory layout, then your program will be in [drive]\work\Project1\bin\Release\ (or possibly \Debug). And you want your log file to be in the directory [drive]\work\Project1\Log.

That directory is the same as [drive]\work\Project1\bin\Release....\Log\

So, one way to do it would be to get the executing program's full path name, extract the directory, and append ....\Log. Like this:

using System.IO; // for Path class
using System.Windows.Forms;  // for Application.ExecutablePath

...

string GetLogFilePath()
{
    string ProgramPath = Path.GetDirectory(Application.ExecutablePath);
    string LogPath = Path.Combine(ProgramPath, @"\..\..\Log\");
    return LogPath;
}

If you don't want to include System.Windows.Forms, you can instead include System.Reflection and get the assembly's location with Assembly.GetExecutingAssembly().Location.
