Answer 1

Finally I solved it NunRar Supports Rar4 format

String filename = @"" + textBox8.Text; string ppath = @"" + System.IO.Path.GetDirectoryName(textBox8.Text) + "\" + System.IO.Path.GetFileNameWithoutExtension(textBox8.Text); string ext = textBox7.Text.Substring(textBox7.Text.IndexOf("."));

            try
            {


                if (ext == ".rar")
                {
                    System.IO.Directory.CreateDirectory(@"" + ppath);
                    try
                    {
                        NUnrar.Archive.RarArchive.WriteToDirectory(filename, ppath, NUnrar.Common.ExtractOptions.ExtractFullPath | NUnrar.Common.ExtractOptions.Overwrite);

                    }
                    catch (Exception ex)
                    {
                        MessageBox.Show(ex.Message);

                    }

                }
                else if (ext == ".zip")
                {
                    System.IO.Directory.CreateDirectory(@"" + ppath);
                    try
                    {
                        ZipFile.ExtractToDirectory(filename, ppath);

                    }
                    catch (Exception ex)
                    {
                        MessageBox.Show(ex.Message);
                    }

                }

            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);

            }
