 private void CopyFolder(string sourceFolder, string destFolder)
        {
            string text = txtNoUpData.Text;
            if (!Directory.Exists(destFolder))
            {
                Directory.CreateDirectory(destFolder);
            }
            string[] files = Directory.GetFiles(sourceFolder);
            foreach (string file in files)
            {
                string name = Path.GetFileName(file);
                string dest = Path.Combine(destFolder, name);
                string lastname = Path.GetExtension(file);
                if (Regex.IsMatch(text, lastname))
                {
                    lastname = lastname.Replace(".", "\\*.");
                    if (Regex.IsMatch(text, lastname)) { proB_UP.Value++;}
                    else
                    {
                        if (Regex.IsMatch(text, name)) { proB_UP.Value++; }
                        else
                        {
                            proB_UP.Value++;
                            File.Delete(dest);
                            File.Copy(file, dest);
                        }
                    }
                }
                else
                {                    proB_UP.Value++;
                    File.Delete(dest);
                    File.Copy(file, dest);
                }
            }
            string[] folders = Directory.GetDirectories(sourceFolder);
            foreach (string folder in folders)
            {
                string name = Path.GetFileName(folder);
                string dest = Path.Combine(destFolder, name);
                CopyFolder(folder, dest);
            }
        }原来这样就行了
