What would you expect the following code to output?
File.WriteAllText("a","1"); DirectoryBackup.CreateHardLink("b", "a", IntPtr.Zero); File.WriteAllText("a","2"); if(File.Exists("c")) File.Delete("c"); File.Move("b","c"); File.WriteAllText("a", "3"); Console.WriteLine(File.ReadAllText("c"));
CreateHardLink is:
[DllImport("kernel32.dll", SetLastError = true, CharSet = CharSet.Auto)] static extern bool CreateHardLink(string lpFileName, string lpExistingFileName, IntPtr lpSecurityAttributes);
