Hi guys,

Need some help to write a custom .NET component to move a large file from one file location to another. I have tried using  the following code. But I am not really sure how to call these C# class from BizTalk Orchestration. Hope I can get some help here. Any suggestions on how to improve the file movement code will be useful too.

Thanks.

        // Display Directory info
        DirectoryInfo dir1 = new DirectoryInfo(@"C:\TestMove\Outgoing");
       
        // Display Files in directory
        FileInfo[] files = dir1.GetFiles("*.*");
        Console.WriteLine("Total number of files: {0}", files.Length);
        foreach (FileInfo f in files)
        {
            String path = "c:\\TestMove\\Outgoing\\" + f.Name;
            String path2 = "D:\\TestMove\\Incoming\\" + f.Name;

            try
            {
                if (!File.Exists(path))
                {
                    // This statement ensures that the file is created,
                    // but the handle is not kept.
                    using (FileStream fs = File.Create(path)) { }
                }

                // Ensure that the target does not exist.
                if (File.Exists(path2))
                {
                    Console.WriteLine("{0}, File exists at target. Do you want to overwrite?", f.Name);
                    Console.WriteLine("Please enter y to overwrite or n to exit");
                    String answer = Console.ReadLine();
                    if (answer == "y")
                    {
                        File.Delete(path2);
                    }
                    else if (answer == "n")

                        Console.Write("File is not overwritten. Program will exit.");
                    }
                    else
                    {
                        Console.Write("Error, nothing is entered. File is not overwritten. Program will exit.");
                    }
                }

                // Move the file.
                File.Move(path, path2);
                Console.WriteLine("{0} was moved to {1}.", path, path2);

                // See if the original exists now.
                if (File.Exists(path))
                {
                    Console.WriteLine("The original file still exists, which is unexpected.");
                }
                else
                {
                    Console.WriteLine("The original file no longer exists, which is expected.");
                }

            }
            catch (Exception e)
            {
                Console.WriteLine("\n\nThe process failed: {0}", e.ToString());
            }
        }
