Help! I get a file not found error regardless of what file I look for or what method I use (copy, read, etc.)! I am running the following code and have tried to reduce to the simplest possible case
(root directory, short file name). I am working on my local pc and the file is on the same pc. I've included the escape character. But whatever I try, I get the error:

'Could not find file "c:\test.txt" '

using System;
using System.IO;

namespace ValidateGPCFile
     /// <summary>
     /// Summary description for clsFileManipulation.
     /// </summary>
     public class clsFileManipulation
     {     public string Message;

          // Default constructor:
          public clsFileManipulation()

          // copy method:
          public void CopyFile()
                    //next line always produces 'cannot find file "c:\test.txt" error
                    File.Copy("c:\\test.txt", "c:\\test1.txt", true);                                            Message = "Valid";
               catch (FileNotFoundException ex)
                                //the code always goes here
                    Message = "Invalid. " + ex.Message;
               }          }

Complete shot in the dark - have you tried using the string literal @ ?

File.Copy(@"c:\test.txt", @"c:\test1.txt", true);
