using System;
using System.IO;
using System.Security;
using System.Security.Permissions;

[assembly:FileIOPermissionAttribute(
     SecurityAction.RequestMinimum,
     All=@"C:\Temp\BCL")]

namespace Samples
{
  public class FileIOPermissionAttributeSample
  {
    public static void Main()
    {
      using(FileStream output =
                         File.Create(@"c:\Temp\BCL\file.txt"))
      {
        Console.WriteLine("Name: {0}", output.Name);
      }
    }
  }
}

The output is

Name: c:\Temp\BCL\file.txt
