Application Path

Sometime I need to retrieve the application path, here I add the four methods I use frequently.

1. The simple way through windows forms:
   using System.Windows.Forms;
   String sAppPath1 = Application.StartupPath;
2. From the binary over reflection:
   String sAppPath2 = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase );
3. Using the file informations:
   FileInfo executableFileInfo = new FileInfo (Application.ExecutablePath);
   String sAppPath3 = executableFileInfo.DirectoryName;
4. When my program is started from another:
   System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);
   

Happy coding.
