// the root directory.
using System;
using System.IO;

namespace IOSamples
{
  public class DirectoryRoot
  {
    public static void Main()
    {
	// Create string for a directory. This value should be an existing directory
	// or the sample will throw a DirectoryNotFoundException.
      string dir = @"C:\test";		
	  try
	  {
		  //Set the current directory.
		  Directory.SetCurrentDirectory(dir);
	  }
	  catch (DirectoryNotFoundException e)
	  {
		  Console.WriteLine("The specified directory does not exist. {0}", e);
	  }
	// Print to console the results.
	  Console.WriteLine("Root directory: {0}", Directory.GetDirectoryRoot(dir));
	  Console.WriteLine("Current directory: {0}", Directory.GetCurrentDirectory());
    }

// If the directory c:\test exists, the output for this sample is:
// Root directory: C:\
// Current directory: C:\test
