Hi all..
  I have a problem.  I have the following peice of code:

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

namespace FileonLan
{

      class Class1
      {
            [STAThread]
            static void Main(string[] args)
            {
                  
                  string path = @"\\PC1\New Folder\temp.txt";
                  try
                  {
                        if (!File.Exists(path))
                        {
                              // Create a file to write to.
                              using (StreamWriter sw = File.CreateText(path))
                              {
                                    sw.WriteLine("Hello");
                                    sw.WriteLine("And");
                                    sw.WriteLine("Welcome");
                              }    
                        }
                        // Open the file to read from.
                        using (StreamReader sr = File.OpenText(path))
                        {
                              string s = "";
                              while ((s = sr.ReadLine()) != null)
                              {
                                    Console.WriteLine(s);
                              }
                        }
                  }

                  catch (Exception ex)
                  {
                        Console.WriteLine(ex.ToString());
                        Console.ReadLine();
                  }

            }
      }
}
