Answer 1

递归就可以搞定
 
void CopyUpdateFile(string srcPath, string aimPath)
        {
            if (aimPath[aimPath.Length - 1] != Path.DirectorySeparatorChar)
                aimPath += Path.DirectorySeparatorChar;
            if (!Directory.Exists(aimPath))
                Directory.CreateDirectory(aimPath);
            if (!Directory.Exists(srcPath))
                return;
            string[] fileList = Directory.GetFileSystemEntries(srcPath);            foreach (string file in fileList)
            {
                int k = file.LastIndexOf("\\");
                string filename = file.Substring(k + 1);
                if (filename.ToLower() != Path.GetFileName(Application.ExecutablePath).ToLower())
                {
                    if (Directory.Exists(file))
                        CopyUpdateFile(file, aimPath + Path.GetFileName(file));
                    else
                    {
                        try
                        {
                            File.Copy(file, aimPath + Path.GetFileName(file), true);
                            //File.Delete(file);
                        }
                        catch (Exception e)
                        {
                           Console.WriteLine("复制文件失败：" + file + e.Message);
                            continue;
                        }
                    }
                }
            }
        }

Answer 2

上面是我以前写的一个函数，大概意思就是这样的 int k = file.LastIndexOf("\\");
                string filename = file.Substring(k + 1);
                if (filename.ToLower() != Path.GetFileName(Application.ExecutablePath).ToLower())把上面这几句去掉，对你没用，你不需要判断

Answer 3

System.IO.Directory.Copy("源目录","目标目录")
